For the more general category of electric drive for all type of vehicles, see electric vehicle. For the specific electric drive cars and SUVs, see electric car and plug-in hybrid.

As of June 2016, the Nissan Leaf (left) is the world's all-time top-selling highway-legal all-electric car (over 228,000), and the Chevrolet Volt (right) is the world's best-selling plug-in hybrid (about 117,300).

A plug-in electric vehicle (PEV) is any motor vehicle that can be recharged from an external source of electricity, such as wall sockets, and the electricity stored in the rechargeable battery packs drives or contributes to drive the wheels. PEV is a subset of electric vehicles that includes all-electric or battery electric vehicles (BEVs), plug-in hybrid vehicles (PHEVs), and electric vehicle conversions of hybrid electric vehicles and conventional internal combustion engine vehicles. In China, plug-in electric vehicles are called new energy vehicles (NEVs).

Plug-in cars have several benefits compared to conventional internal combustion engine vehicles. They have lower operating and maintenance costs, and produce little or no local air pollution. They reduce dependence on petroleum and may reduce greenhouse gas emissions from the onboard source of power, depending on the fuel and technology used for electricity generation to charge the batteries. Plug-in hybrids capture most of these benefits when they are operating in all-electric mode. Despite their potential benefits, market penetration of plug-in electric vehicles has been slower than expected as adoption faces several hurdles and limitations. The stock of plug-in electric cars represented just 0.1% of the one billion cars on the world's roads by the end of 2015.

As of September 2016, plug-in electric vehicles are more expensive than conventional vehicles and hybrid electric vehicles due to the additional cost of their lithium-ion battery packs. Other factors discouraging the adoption of electric cars are the lack of public and private recharging infrastructure and, in the case of all-electric vehicles, drivers' fear of the batteries running out of energy before reaching their destination due to the limited range of existing electric cars. Plug-in hybrids eliminate the problem of range anxiety associated to all-electric vehicles, because the combustion engine works as a backup when the batteries are depleted, giving PHEVs driving range comparable to other vehicles with gasoline tanks. Several national and local governments have established tax credits, subsidies, and other incentives to promote the introduction and adoption in the mass market of plug-in electric vehicles depending on their battery size and all-electric range.

As of September 2016, there are about 70 models of highway legal plug-in electric passenger cars and light-duty utility vans available for retail sales in the world. Cumulative global sales of highway legal plug-in electric passenger cars and light utility vehicles passed the 1.5 million unit milestone in May 2016. As of June 2016, the Nissan Leaf ranked as the world's all-time top selling highway-capable all-electric car, with global sales of more than 228,000 units, followed by the Tesla Model S with over 129,000 units sold worldwide, and the Chevrolet Volt plug-in hybrid, which together with its sibling the Opel/Vauxhall Ampera has combined global sales of about 117,300 units. Ranking next is the Mitsubishi Outlander P-HEV with about 107,400 units sold.

As of September 2016, cumulative sales of highway legal light-duty plug-in electric vehicles by country are led by the United States and China, both with about 522,000 plug-in passenger cars sold. Japan is the world's third largest plug-in car market with about 145,000 plug-ins sold through September 2016. About 570,000 light-duty plug-in electric passenger cars have been registered in Europe up until September 2016, representing almost a third of global sales, and making the continent the world's largest light-duty plug-in regional market. As of September 2016, sales in the European light-duty plug-in electric segment, which includes utility vans, are led by Norway with over 121,300 units, followed by France with over 100,000 units registered by October 2016, and the Netherlands with almost 98,300. China is the world's leader in the plug-in heavy-duty segment, including electric all-electric buses, and plug-in commercial and sanitation trucks. The stock of new energy vehicles sold in China totaled more than 733,000 units through September 2016. As of December 2015, China was the world's largest plug-in electric bus market with a stock of almost 173,000 vehicles.

Plug-in electric vehicle

A plug-in electric vehicle (PEV) is any motor vehicle with rechargeable battery packs that can be charged from the electric grid, and the electricity stored on board drives or contributes to drive the wheels for propulsion. Plug-in electric vehicles are also sometimes referred to as grid-enabled vehicles (GEV) and also as electrically chargeable vehicles.

PEV is a subcategory of electric vehicles that includes battery electric vehicles (BEVs), plug-in hybrid vehicles, (PHEVs), and electric vehicle conversions of hybrid electric vehicles and conventional internal combustion engine vehicles. Even though conventional hybrid electric vehicles (HEVs) have a battery that is continually recharged with power from the internal combustion engine and regenerative braking, they can not be recharged from an off-vehicle electric energy source, and therefore, they do not belong to the category of plug-in electric vehicles.

"Plug-in electric drive vehicle" is the legal term used in U.S. federal legislation to designate the category of motor vehicles eligible for federal tax credits depending on battery size and their all-electric range. In some European countries, particularly in France, "electrically chargeable vehicle" is the formal term used to designate the vehicles eligible for these incentives. While the term "plug-in electric vehicle" most often refers to automobiles or "plug-in cars", there are several other types of plug-in electric vehicle, including scooters, motorcycles, neighborhood electric vehicles or microcars, city cars, vans, light trucks or light commercial vehicles, buses, trucks or lorries, and military vehicles.

Battery electric vehicles

Main article: Battery electric vehicle

U.S. Army GEM e2 neighborhood electric vehicle.

A battery electric vehicle (BEV) uses chemical energy stored in rechargeable battery packs as its only source for propulsion. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion.

A plug-in hybrid operates as an all-electric vehicle or BEV when operating in charge-depleting mode, but it switches to charge-sustaining mode after the battery has reached its minimum state of charge (SOC) threshold, exhausting the vehicle's all-electric range (AER).

Plug-in hybrid electric vehicles

Main article: Plug-in hybrid

A plug-in hybrid electric vehicle (PHEV or PHV), also known as a plug-in hybrid, is a hybrid electric vehicle with rechargeable batteries that can be restored to full charge by connecting a plug to an external electric power source. A plug-in hybrid shares the characteristics of both a conventional hybrid electric vehicle and an all-electric vehicle: it uses a gasoline engine and an electric motor for propulsion, but a PHEV has a larger battery pack that can be recharged, allowing operation in all-electric mode until the battery is depleted.

Several Prius+ converted plug-in hybrids.

Aftermarket conversions

See also: Plug-in hybrid conversions and electric vehicle conversion

An aftermarket electric vehicle conversion is the modification of a conventional internal combustion engine vehicle (ICEV) or hybrid electric vehicle (HEV) to electric propulsion, creating an all-electric or plug-in hybrid electric vehicle.

There are several companies in the U.S. offering conversions. The most common conversions have been from hybrid electric cars to plug-in hybrid, but due to the different technology used in hybrids by each carmaker, the easiest conversions are for 2004–2009 Toyota Prius and for the Ford Escape/Mercury Mariner Hybrid.

New energy vehicles

In China the term new energy vehicles (NEVs) refers to vehicles that are partially or fully powered by electricity, such as battery electric vehicles (BEVs) and plug-in hybrids (PHEVs). The Chinese government began implementation of its NEV program in 2009 to foster the development and introduction of new energy vehicles.

Advantages

Lower operating and maintenance costs

Internal combustion engines are relatively inefficient at converting on-board fuel energy to propulsion as most of the energy is wasted as heat, and the rest while the engine is idling. Electric motors, on the other hand, are more efficient at converting stored energy into driving a vehicle. Electric drive vehicles do not consume energy while at rest or coasting, and modern plug-in cars can capture and reuse as much as one fifth of the energy normally lost during braking through regenerative braking. Typically, conventional gasoline engines effectively use only 15% of the fuel energy content to move the vehicle or to power accessories, and diesel engines can reach on-board efficiencies of 20%, while electric drive vehicles typically have on-board efficiencies of around 80%.

The operating cost of the Toyota Prius Plug-in Hybrid in the U.S. is estimated at US$0.03 per mile while operating in all-electric mode.

In the United States, as of early 2010 with a national average electricity rate of US$0.10 per kWh, the cost per mile for a plug-in electric vehicle operating in all-electric mode is estimated between $0.02 to $0.04, while the cost per mile of a standard automobile varies between $0.08 to $0.20, considering a gasoline price of $3.00 per gallon. As petroleum price is expected to increase in the future due to oil production decline and increases in global demand, the cost difference in favor of PEVs is expected to become even more advantageous.

According to Consumer Reports, as of December 2011 the Nissan Leaf has a cost of 3.5 cents per mile and the Chevrolet Volt has a cost in electric mode of 3.8 cents per mile. The Volt cost per mile is higher because it is heavier than the Leaf. These estimates are based on the fuel economy and energy consumption measured on their tests and using a U.S. national average rate of 11 cents per kWh of electricity. When the Volt runs in range-extended mode using its premium gasoline-powered engine, the plug-in hybrid has a cost of 12.5 cents per mile. The out-of-pocket cost per mile of the three most fuel efficient gasoline-powered cars as tested by the magazine are the Toyota Prius, with a cost of 8.6 cents per miles, the Honda Civic Hybrid with 9.5 cents per mile, the Toyota Corolla with 11.9 cents per mile, and the Hyundai Elantra 13.1 cents per mile. The analysis also found that on trips up to 100 mi (160 km), the Volt is cheaper to drive than the Prius and the other three cars due to the Volt's 35 mi (56 km) driving range on electricity. The previous operating costs do not include maintenance, depreciation or other costs.

All-electric and plug-in hybrid vehicles also have lower maintenance costs as compared to internal combustion vehicles, since electronic systems break down much less often than the mechanical systems in conventional vehicles, and the fewer mechanical systems on board last longer due to the better use of the electric engine. PEVs do not require oil changes and other routine maintenance checks.

Template:Comparison electric car efficiency The following table compares EPA's estimated out-of-pocket fuel costs and fuel economy ratings of serial production plug-in hybrid electric vehicles rated by EPA as of January 2017 expressed in miles per gallon gasoline equivalent (mpg-e), versus the most fuel efficient gasoline-electric hybrid car, the 2016 Toyota Prius Eco (fourth generation), rated 56 mpg_‑US (4.2 L/100 km; 67 mpg_‑imp), and EPA's average new 2016 vehicle, which has a fuel economy of 25 mpg_‑US (9.4 L/100 km; 30 mpg_‑imp). The table also shows the fuel efficiency for plug-in hybrids in all-electric mode expressed as KWh/100 mile, the metric used by EPA to rate electric cars before November 2010.

Notes: (1) Based on 45% highway and 55% city driving. Electricity cost of US$0.13/kWh, premium gasoline price of US$2.51 per gallon (used by the 2015 Volt, i3 REx, ELR, i8, Mercedes S500e, Karma and all Porsche models), and regular gasoline price of US$2.04 per gallon (as of 18 December 2015). Conversion 1 gallon of gasoline=33.7 kWh.

The Edison Electric Institute (EEI) conducted an analysis that demonstrated that between January 1976 and February 2012 the real price for gasoline has been much more volatile than the real price of electricity in the United States. The analysis is based on a plug-in electric vehicle with an efficiency of 3.4 miles per kW-hr (like the Mitsubishi i MiEV) and a gasoline-powered vehicle with a fuel economy rated at 30 mpg_‑US (7.8 L/100 km; 36 mpg_‑imp) (like the 2012 Fiat 500). The EEI estimated that operating a plug-in would have had an equivalent cost of around US$1.50 a gallon in the late 1970s and early 1980s, and around US$1.00 a gallon since the late 1990s. In contrast, the price to operate an internal combustion engine vehicle has had much ample variations, costing more than US$3.50 per gallon during the 1979 energy crisis, then had a couple of lows with prices at less than US$1.50 during 1999 and 2001, only to climb and reach a maximum of more than US$4.00 before the beginning of the 2007–2009 financial crisis, by early 2012 has fluctuated around US$3.50. The analysis found that the cost of an equivalent electric-gallon of gasoline would have been not only cheaper to operate during the entire analysis period but also that equivalent electricity prices are more stable and have been declining in terms of equivalent dollars per gallon.

Air pollution and greenhouse gas emissions

See also: Air pollution and carbon emissions in electric cars and Greenhouse gas emissions in plug-in hybrids

RechargeIT converted Toyota Prius plug-in hybrids at Google's Mountain View campus. The garage has recharging facilities powered by solar panels.

Electric cars, as well as plug-in hybrids operating in all-electric mode, emit no harmful tailpipe pollutants from the onboard source of power, such as particulates (soot), volatile organic compounds, hydrocarbons, carbon monoxide, ozone, lead, and various oxides of nitrogen. The clean air benefit is usually local because, depending on the source of the electricity used to recharge the batteries, air pollutant emissions are shifted to the location of the generation plants. In a similar manner, plug-in electric vehicles operating in all-electric mode do not emit greenhouse gases from the onboard source of power, but from the point of view of a well-to-wheel assessment, the extent of the benefit also depends on the fuel and technology used for electricity generation. This fact has been referred to as the long tailpipe of plug-in electric vehicles. From the perspective of a full life cycle analysis, the electricity used to recharge the batteries must be generated from renewable or clean sources such as wind, solar, hydroelectric, or nuclear power for PEVs to have almost none or zero well-to-wheel emissions. On the other hand, when PEVs are recharged from coal-fired plants, they usually produce slightly more greenhouse gas emissions than internal combustion engine vehicles and higher than hybrid electric vehicles. In the case of plug-in hybrid electric vehicles operating in hybrid mode with assistance of the internal combustion engine, tailpipe and greenhouse emissions are lower in comparison to conventional cars because of their higher fuel economy.

The magnitude of the potential advantage depends on the mix of generation sources and therefore varies by country and by region. For example, France can obtain significant emission benefits from electric and plug-in hybrids because most of its electricity is generated by nuclear power plants; California, where most energy comes from natural gas, hydroelectric and nuclear plants can also secure substantial emission benefits. The U.K. also has a significant potential to benefit from PEVs as natural gas plants dominate the generation mix. On the other hand, emission benefits in Germany, China, India, and the central regions of the United States are limited or non-existent because most electricity is generated from coal. However these countries and regions might still obtain some air quality benefits by reducing local air pollution in urban areas. Cities with chronic air pollution problems, such as Los Angeles, México City, Santiago, Chile, São Paulo, Beijing, Bangkok and Kathmandu may also gain local clean air benefits by shifting the harmful emission to electric generation plants located outside the cities. Nevertheless, the location of the plants is not relevant when considering greenhouse gas emission because their effect is global.

Carbon footprint during production

Ricardo

A report published in June 2011, prepared by Ricardo in collaboration with experts from the UK's Low Carbon Vehicle Partnership, found that hybrid electric cars, plug-in hybrids and all-electric cars generate more carbon emissions during their production than current conventional vehicles, but still have a lower overall carbon footprint over the full life cycle. The higher carbon footprint during production of electric drive vehicles is due mainly to the production of batteries. As an example, 43 percent of production emissions for a mid-size electric car are generated from the battery production, while for standard mid-sized gasolineinternal combustion engine vehicle, around 75% of the embedded carbon emissions during production comes from the steel used in the vehicle glider. The following table summarizes key results of this study for four powertrain technologies:

Comparison of full life cycle assessment(well-to-wheels) of carbon emissions and carbon footprint during production for four different powertrain technologies
Type of vehicle (powertrain)	Estimated emissions in production (tonnes CO2e)	Estimated lifecycle emissions (tonnes CO2e)	Percentage of emissions during production
Standard gasoline vehicle	5.6	24	23%
Hybrid electric vehicle	6.5	21	31%
Plug-in hybrid electric vehicle	6.7	19	35%
Battery electric vehicle	8.8	19	46%
Notes: Estimates based upon a 2015 model vehicle assuming 150,000 km (93,000 mi) full life travel using 10% ethanol blend and 500g/kWh grid electricity.

The Ricardo study also found that the lifecycle carbon emissions for mid-sized gasoline and diesel vehicles are almost identical, and that the greater fuel efficiency of the diesel engine is offset by higher production emissions.

Volkswagen

In 2014 Volkswagen published the results of life-cycle assessment of its electric vehicles certified by TÜV NORD, and independent inspection agency. The study found that CO
₂ emissions during the use phase of its all-electric VW e-Golf are 99% lower than those of the Golf 1.2 TSI when powers comes from exclusively hydroelectricity generated in Germany, Austria and Switzerland. Accounting for the full lifecycle, the e-Golf reduces emissions by 61%, offsetting higher production emissions. When the actual EU-27 electricity mix is considered, the e-Golf emissions are still 26% lower than those of the conventional Golf 1.2 TSI. Similar results were found when comparing the e-Golf with the Golf 1.6 TDI. The analysis considered recycling of the three vehicles at the end of their lifetime.

Environmental Protection Agency

The following table compares tailpipe and upstream CO₂ emissions estimated by the U.S. Environmental Protection Agency for all series production model year 2014 plug-in electric vehicles available in the U.S. market. Total emissions include the emissions associated with the production and distribution of electricity used to charge the vehicle, and for plug-in hybrid electric vehicles, it also includes emissions associated with tailpipe emissions produced from the internal combustion engine. These figures were published by the EPA in October 2014 in its annual report "Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 Through 2014." All emissions are estimated considering average real world city and highway operation based on the EPA 5-cycle label methodology, using a weighted 55% city and 45% highway driving. For the first time, the 2014 Trends report presents an analysis of the impact of alternative fuel vehicles, with emphasis in plug-in electric vehicles because as their market share is approaching 1%, the EPA concluded that PEVs began to have a measurable impact on the U.S. overall new vehicle fuel economy and CO₂ emissions.

For purposes of an accurate estimation of emissions, the analysis took into consideration the differences in operation between plug-in hybrids. Some, like the Chevrolet Volt, can operate in all-electric mode without using gasoline, and others operate in a blended mode like the Toyota Prius PHV, which uses both energy stored in the battery and energy from the gasoline tank to propel the vehicle, but that can deliver substantial all-electric driving in blended mode. In addition, since the all-electric range of plug-in hybrids depends on the size of the battery pack, the analysis introduced a utility factor as a projection of the share of miles that will be driven using electricity by an average driver, for both, electric only and blended EV modes. Since all-electric cars do not produce tailpipe emissions, the utility factor applies only to plug-in hybrids. The following table shows the overall fuel economy expressed in terms of miles per gallon gasoline equivalent (mpg-e) and the utility factor for the ten MY2014 plug-in hybrids available in the U.S. market, and EPA's best estimate of the CO₂ tailpipe emissions produced by these PHEVs.

In order to account for the upstream CO₂ emissions associated with the production and distribution of electricity, and since electricity production in the United States varies significantly from region to region, the EPA considered three scenarios/ranges with the low end scenario corresponding to the California powerplant emissions factor, the middle of the range represented by the national average powerplant emissions factor, and the upper end of the range corresponding to the powerplant emissions factor for the Rocky Mountains. The EPA estimates that the electricity GHG emission factors for various regions of the country vary from 346 g CO₂/kWh in California to 986 g CO₂/kWh in the Rockies, with a national average of 648 g CO₂/kWh.

Union of Concerned Scientists

The Union of Concerned Scientists (UCS) published a study in 2012 that assessed average greenhouse gas emissions in the U.S. resulting from charging plug-in car batteries from the perspective of the full life-cycle (well-to-wheel analysis) and according to fuel and technology used to generate electric power by region. The study used the model year 2011 Nissan Leaf all-electric car to establish the analysis baseline, and electric-utility emissions are based on EPA's 2009 estimates. The UCS study expressed the results in terms of miles per gallon instead of the conventional unit of grams of greenhouse gases or carbon dioxide equivalent emissions per year in order to make the results more friendly for consumers. The study found that in areas where electricity is generated from natural gas, nuclear, hydroelectric or renewable sources, the potential of plug-in electric cars to reduce greenhouse emissions is significant. On the other hand, in regions where a high proportion of power is generated from coal, hybrid electric cars produce less CO₂ equivalent emissions than plug-in electric cars, and the best fuel efficient gasoline-powered subcompact car produces slightly less emissions than a PEV. In the worst-case scenario, the study estimated that for a region where all energy is generated from coal, a plug-in electric car would emit greenhouse gas emissions equivalent to a gasoline car rated at a combined city/highway driving fuel economy of 30 mpg_‑US (7.8 L/100 km; 36 mpg_‑imp). In contrast, in a region that is completely reliant on natural gas, the PEV would be equivalent to a gasoline-powered car rated at 50 mpg_‑US (4.7 L/100 km; 60 mpg_‑imp).

The study concluded that for 45% of the U.S. population, a plug-in electric car will generate lower CO₂ equivalent emissions than a gasoline-powered car capable of combined 50 mpg_‑US (4.7 L/100 km; 60 mpg_‑imp), such as the Toyota Prius and the Prius c. The UCS also found that for 37% of the population, the electric car emissions will fall in the range of a gasoline-powered car rated at a combined fuel economy of 41 to 50 mpg_‑US (5.7 to 4.7 L/100 km; 49 to 60 mpg_‑imp), such as the Honda Civic Hybrid and the Lexus CT200h. Only 18% of the population lives in areas where the power-supply is more dependent on burning carbon, and the greenhouse gas emissions will be equivalent to a car rated at a combined fuel economy of 31 to 40 mpg_‑US (7.6 to 5.9 L/100 km; 37 to 48 mpg_‑imp), such as the Chevrolet Cruze and Ford Focus. The study found that there are no regions in the U.S. where plug-in electric cars will have higher greenhouse gas emissions than the average new compact gasoline engine automobile, and the area with the dirtiest power supply produces CO₂ emissions equivalent to a gasoline-powered car rated at 33 mpg_‑US (7.1 L/100 km).

In September 2014 the UCS published an updated analysis of its 2012 report. The 2014 analysis found that 60% of Americans, up from 45% in 2009, live in regions where an all-electric car produce fewer CO₂ equivalent emissions per mile than the most efficient hybrid. The UCS study found several reasons for the improvement. First, electric utilities have adopted cleaner sources of electricity to their mix between the two analysis. The 2014 study used electric-utility emissions based on EPA's 2010 estimates, but since coal use nationwide is down by about 5% from 2010 to 2014, actual efficiency in 2014 is better than estimated in the UCS study. Second, electric vehicles have become more efficient, as the average 2013 all-electric vehicle used 0.33 kWh per mile, representing a 5% improvement over 2011 models. Also, some new models are cleaner than the average, such as the BMW i3, which is rated at 0.27 kWh by the EPA. An i3 charged with power from the Midwest grid would be as clean as a gasoline-powered car with about 50 mpg_‑US (4.7 L/100 km), up from 39 mpg_‑US (6.0 L/100 km) for the average electric car in the 2012 study. In states with a cleaner mix generation, the gains were larger. The average all-electric car in California went up to 95 mpg_‑US (2.5 L/100 km) equivalent from 78 mpg_‑US (3.0 L/100 km) in the 2012 study. States with dirtier generation that rely heavily on coal still lag, such as Colorado, where the average BEV only achieves the same emissions as a 34 mpg_‑US (6.9 L/100 km; 41 mpg_‑imp) gasoline-powered car. The author of the 2014 analysis noted that the benefits are not distributed evenly across the U.S. because electric car adoptions is concentrated in the states with cleaner power.

Source: Union of Concerned Scientists.

In November 2015 the Union of Concerned Scientists published a new report comparing two battery electric vehicles (BEVs) with similar gasoline vehicles by examining their global warming emissions over their full life-cycle, cradle-to-grave analysis. The two BEVs modeled, midsize and full-size, are based on the two most popular BEV models sold in the United States in 2015, the Nissan Leaf and the Tesla Model S. The study found that all-electric cars representative of those sold today, on average produce less than half the global warming emissions of comparable gasoline-powered vehicles, despite taken into account the higher emissions associated with BEV manufacturing. Considering the regions where the two most popular electric cars are being sold, excess manufacturing emissions are offset within 6 to 16 months of average driving. The study also concluded that driving an average EV results in lower global warming emissions than driving a gasoline car that gets 50 mpg_‑US (4.7 L/100 km) in regions covering two-thirds of the U.S. population, up from 45% in 2009. Based on where EVs are being sold in the United States in 2015, the average EV produces global warming emissions equal to a gasoline vehicle with a 68 mpg_‑US (3.5 L/100 km) fuel economy rating. The authors identified two main reason for the fact that EV-related emissions have become even lower in many parts of the country since the first study was conducted in 2012. Electricity generation has been getting cleaner, as coal-fired generation has declined while lower-carbon alternatives have increased. In addition, electric cars are becoming more efficient. For example, the Nissan Leaf and the Chevrolet Volt, have undergone improvements to increase their efficiencies compared to the original models launched in 2010, and other even more efficient BEV models, such as the most lightweight and efficient BMW i3, have entered the market.

National Bureau of Economic Research

One criticism to the UCS study is that the analysis was made using average emissions rates across regions instead of marginal generation at different times of the day. The former approach does not take into account the generation mix within interconnected electricity markets and shifting load profiles throughout the day. An analysis by three economist affiliated with the National Bureau of Economic Research (NBER), published in November 2014, developed a methodology to estimate marginal emissions of electricity demand that vary by location and time of day across the United States. The marginal analysis, applied to plug-in electric vehicles, found that the emissions of charging PEVs vary by region and hours of the day. In some regions, such as the Western U.S. and Texas, CO₂ emissions per mile from driving PEVs are less than those from driving a hybrid car. However, in other regions, such as the Upper Midwest, charging during the recommended hours of midnight to 4 a.m. implies that PEVs generate more emissions per mile than the average car currently on the road. The results show a fundamental tension between electricity load management and environmental goals as the hours when electricity is the least expensive to produce tend to be the hours with the greatest emissions. This occurs because coal-fired units, which have higher emission rates, are most commonly used to meet base-level and off-peak electricity demand; while natural gas units, which have relatively low emissions rates, are often brought online to meet peak demand.

Well-to-wheel GHG emissions in several countries

A study published in the UK in April 2013 assessed the carbon footprint of plug-in electric vehicles in 20 countries. As a baseline the analysis established that manufacturing emissions account for 70 g CO₂/km for an electric car and 40 g CO₂/km for a petrol car. The study found that in countries with coal-intensive generation, PEVs are no different from conventional petrol-powered vehicles. Among these countries are China, Indonesia, Australia, South Africa and India. A pure electric car in India generates emissions comparable to a 20 mpg_‑US (12 L/100 km; 24 mpg_‑imp) petrol car.

The country ranking was led by Paraguay, where all electricity is produced from hydropower, and Iceland, where electricity production relies on renewable power, mainly hydro and geothermal power. Resulting carbon emissions from an electric car in both countries are 70 g CO₂/km, which is equivalent to a 220 mpg_‑US (1.1 L/100 km; 260 mpg_‑imp) petrol car, and correspond to manufacturing emissions. Next in the ranking are other countries with low carbon electricity generation, including Sweden (mostly hydro and nuclear power ), Brazil (mainly hydropower) and France (predominantly nuclear power). Countries ranking in the middle include Japan, Germany, the UK and the United States.

The following table shows the emissions intensity estimated in the study for those countries where electric vehicle are available, and the corresponding emissions equivalent in miles per US gallon of a petrol-powered car:

Less dependence on imported oil

See also: Energy resilience, Energy security, and Mitigation of peak oil

Evolution of oil prices since 1987 (average Brent spot prices – adjusted for U.S. inflation).

For many net oil importing countries the 2000s energy crisis brought back concerns first raised during the 1973 oil crisis. For the United States, the other developed countries and emerging countries their dependence on foreign oil has revived concerns about their vulnerability to price shocks and supply disruption. Also, there have been concerns about the uncertainty surrounding peak oil production and the higher cost of extracting unconventional oil. A third issue that has been raised is the threat to national security because most proven oil reserves are concentrated in relatively few geographic locations, including some countries with strong resource nationalism, unstable governments or hostile to U.S. interests. In addition, for many developing countries, and particularly for the poorest African countries, high oil prices have an adverse impact on the government budget and deteriorate their terms of trade thus jeopardizing their balance of payments, all leading to lower economic growth.

Through the gradual replacement of internal combustion engine vehicles for electric cars and plug-in hybrids, electric drive vehicles can contribute significantly to lessen the dependence of the transport sector on imported oil as well as contributing to the development of a more resilient energy supply.

Vehicle-to-grid

Main article: Vehicle-to-grid

Plug-in electric vehicles offer users the opportunity to sell electricity stored in their batteries back to the power grid, thereby helping utilities to operate more efficiently in the management of their demand peaks. A vehicle-to-grid (V2G) system would take advantage of the fact that most vehicles are parked an average of 95 percent of the time. During such idle times the electricity stored in the batteries could be transferred from the PEV to the power lines and back to the grid. In the U.S this transfer back to the grid have an estimated value to the utilities of up to $4,000 per year per car. In a V2G system it would also be expected that battery electric (BEVs) and plug-in hybrids (PHEVs) would have the capability to communicate automatically with the power grid to sell demand response services by either delivering electricity into the grid or by throttling their charging rate.

Cost of batteries and cost of ownership

Main article: Electric vehicle battery

Cost of batteries

As of 2015, plug-in electric vehicles are significantly more expensive as compared to conventional internal combustion engine vehicles and hybrid electric vehicles due to the additional cost of their lithium-ion battery pack. According to a 2010 study by the National Research Council, the cost of a lithium-ion battery pack was about US$1,700/kWh of usable energy, and considering that a PHEV-10 requires about 2.0 kWh and a PHEV-40 about 8 kWh, the manufacturer cost of the battery pack for a PHEV-10 is around US$3,000 and it goes up to US$14,000 for a PHEV-40. As of June 2012, and based on the three battery size options offered for the Tesla Model S, the New York Times estimated the cost of automotive battery packs between US$400 to US$500 per kilowatt-hour. A 2013 study by the American Council for an Energy-Efficient Economy reported that battery costs came down from US$1,300 per kWh in 2007 to US$500 per kWh in 2012. The U.S. Department of Energy has set cost targets for its sponsored battery research of US$300 per kWh in 2015 and US$125 per kWh by 2022. Cost reductions through advances in battery technology and higher production volumes will allow plug-in electric vehicles to be more competitive with conventional internal combustion engine vehicles.

According to a study published in February 2016 by Bloomberg New Energy Finance (BNEF), battery prices fell 65% since 2010, and 35% just in 2015, reaching US$350 per kWh. The study concludes that battery costs are on a trajectory to make electric vehicles without government subsidies as affordable as internal combustion engine cars in most countries by 2022. BNEF projects that by 2040, long-range electric cars will cost less than US$22,000 expressed in 2016 dollars. BNEF expects electric car battery costs to be well below US$120 per kWh by 2030, and to fall further thereafter as new chemistries become available.

Cost of ownership

A study published in 2011 by the Belfer Center, Harvard University, found that the gasoline costs savings of plug-in electric cars do not offset their higher purchase prices when comparing their lifetime net present value of purchase and operating costs for the U.S. market at 2010 prices, and assuming no government subidies. According to the study estimates, a PHEV-40 is US$5,377 more expensive than a conventional internal combustion engine, while a battery electric vehicles is US$4,819 more expensive. These findings assumed a battery cost of US$600 per kWh, which means that the Chevrolet Volt battery pack cost around US$10,000 and the Nissan Leaf pack costs US$14,400. The study also assumed a gasoline price of US$3.75 per gallon (as of mid June 2011), that vehicles are driven 12,000 miles (19,000 km) per year, an average price of electricity of US$0.12 per kWh, that the plug-in hybrid is driven in all-electric mode 85% of the time, and that the owner of PEVs pay US$1,500 to install a Level II 220/240 volt charger at home.

The study also include hybrid electric vehicles in the comparison, and analyzed several scenarios to determine how the comparative net savings will change over the next 10 to 20 years, assuming that battery costs will decrease while gasoline prices increase, and also assuming higher fuel efficiency of conventional cars, among other scenarios. Under the future scenarios considered, the study found that BEVs will be significantly less expensive than conventional cars (US$1,155 to US$7,181 cheaper), while PHEVs, will be more expensive than BEVs in almost all comparison scenarios, and only less expensive than conventional cars in a scenario with very low battery costs and high gasoline prices. The reason for the different savings among PEVs is because BEVs are simpler to build and do not use liquid fuel, while PHEVs have more complicated powertrains and still have gasoline-powered engines. The following table summarizes the results of four of the seven scenarios analyzed by the study.

Note: Assumes vehicles are driven 12,000 miles (19,000 km) per year and plug-in hybrid is driven in all-electric mode 85% of the time. Does not take into account other differences in cost of ownership.

According to a study by the Electric Power Research Institute published in June 2013, the total cost of ownership of the 2013 Nissan Leaf SV is substantially lower than that of comparable conventional and hybrid vehicles. For comparison, the study constructed average hybrid and conventional vehicles and assumed an average US distance per trip distribution. The study took into account the manufacturer's suggested retail price, taxes, credits, destination charge, electric charging station, fuel cost, maintenance cost, and additional cost due to the use of a gasoline vehicle for trips beyond the range of the Leaf.

Average Conventional	Gasoline	$44,949	$46,561
Average Hybrid	Gasoline-electric hybrid	$44,325	$45,416
Notes: Costs are based on a gasoline price of $3.64 per gallon, an electricity rate of $0.12/kWh, and a vehicle lifetime of 150,000 miles. The average conventional car was constructed by averaging of Honda Civic EX, Chevrolet Cruze LTZ, Ford Focus Titanium, and Volkswagen Passat. The average hybrid car was constructed from Ford Fusion Hybrid, Honda Civic Hybrid, Toyota Camry Hybrid XLE, and Toyota Prius trim IV.

Availability of recharging infrastructure

See also: Charging station and Range anxiety

Despite the widespread assumption that plug-in recharging will take place overnight at home, residents of cities, apartments, dormitories, and townhouses do not have garages or driveways with available power outlets, and they might be less likely to buy plug-in electric vehicles unless recharging infrastructure is developed. Electrical outlets or charging stations near their places of residence, in commercial or public parking lots, streets and workplaces are required for these potential users to gain the full advantage of PHEVs, and in the case of EVs, to avoid the fear of the batteries running out energy before reaching their destination, commonly called range anxiety. Even house dwellers might need to charge at the office or to take advantage of opportunity charging at shopping centers. However, this infrastructure is not in place and it will require investments by both the private and public sectors.

Several cities in California and Oregon, and particularly San Francisco and other cities in the San Francisco Bay Area and Silicon Valley, already have deployed public charging stations and have expansion plans to attend both plug-ins and all-electric cars. Some local private firms such as Google and Adobe Systems have also deployed charging infrastructure. In Google's case, its Mountain View campus has 100 available charging stations for its share-use fleet of converted plug-ins available to its employees. Solar panels are used to generate the electricity, and this pilot program is being monitored on a daily basis and performance results are published on the RechargeIT website. As of December 2013, Estonia is the first and only country that had deployed an EV charging network with nationwide coverage, with 165 fast chargers available along highways at a minimum distance of between 40 to 60 km (25 to 37 mi), and a higher density in urban areas.

The importance to build the infrastructure necessary to support electric vehicles is illustrated by the decision of Car2Go in San Diego, California, that due to insufficient charging infrastructure decided to replace all of its all-electric car fleet with gasoline-powered cars starting on 1 May 2016. When the carsharing service started in 2011, Car2Go expected 1,000 charging stations to be deployed around the city, but only 400 were in place by early 2016. As a result, an average of 20% of the carsharing fleet is unavailable at any given time because the cars are either being charged or because they don’t have enough electricity in them to be driven. Also, many of the company’s 40,000 San Diego members say they often worry their Car2Go will run out of charge before they finish their trip.

Battery swapping

Better Place's battery switching station in Israel

A different approach to resolve the problems of range anxiety and lack of recharging infrastructure for electric vehicles was developed by Better Place. Its business model considers that electric cars are built and sold separately from the battery pack. As customers are not allowed to purchase battery packs, they must lease them from Better Place which will deploy a network of battery swapping stations thus expanding EVs range and allowing long distance trips. Subscribed users pay a per-distance fee to cover battery pack leasing, charging and swap infrastructure, the cost of sustainable electricity, and other costs. Better Place signed agreement for deployment in Australia, Denmark, Israel, Canada, California, and Hawaii. The Renault Fluence Z.E. was the electric car built with switchable battery technology sold for the Better Place network. The robotic battery-switching operation was completed in about five minutes.

After implementing the first modern commercial deployment of the battery swapping model in Israel and Denmark, Better Place filed for bankruptcy in Israel in May 2013. The company's financial difficulties were caused by the high investment required to develop the charging and swapping infrastructure, about US$850 million in private capital, and a market penetration significantly lower than originally predicted by Shai Agassi. Less than 1,000 Fluence Z.E. cars were deployed in Israel and around 400 units in Denmark.

Tesla Motors designed its Model S to allow fast battery swapping. In June 2013, Tesla announced their goal to deploy a battery swapping station in each of its supercharging stations. At a demonstration event Tesla showed that a battery swap operation with the Model S takes just over 90 seconds, about half the time it takes to refill a gasoline-powered car used for comparison purposes during the event. The first stations are planned to be deployed along Interstate 5 in California where, according to Tesla, a large number of Model S sedans make the San Francisco-Los Angeles trip regularly. These will be followed by the Washington, DC to Boston corridor.

The REVA NXR exhibited in the 2009 Frankfurt Motor Show and the Nissan Leaf SV trim both have roof-mounted solar panels. These solar panels are designed to trickle charge the batteries when the car is moving or parked. Another proposed technology is REVive, by REVA. When the REVA NXR's batteries are running low or are fully depleted, the driver is able to send an SMS to REVive and unlock a hidden reserve in the battery pack. REVA has not provided details on how the system will work. The Fisker Karma uses solar panel in the roof to recharge the 12-volt lead-acid accessory battery. The Nissan Leaf SL trim also has a small solar panel at the rear of the roof/spoiler that can trickle charge the auxiliary 12-volt lead-acid battery.

Potential overload of the electrical grid

The existing electrical grid, and local transformers in particular, may not have enough capacity to handle the additional power load that might be required in certain areas with high plug-in electric car concentrations. As recharging a single electric-drive car could consume three times as much electricity as a typical home, overloading problems may arise when several vehicles in the same neighborhood recharge at the same time, or during the normal summer peak loads. To avoid such problems, utility executives recommend owners to charge their vehicles overnight when the grid load is lower or to use smarter electric meters that help control demand. When market penetration of plug-in electric vehicles begins to reach significant levels, utilities will have to invest in improvements for local electrical grids in order to handle the additional loads related to recharging to avoid blackouts due to grid overload. Also, some experts have suggested that by implementing variable time-of-day rates, utilities can provide an incentive for plug-in owners to recharge mostly overnight, when rates are lower.

General Motors is sponsoring the Pecan Street demonstration project in Austin, Texas. The project objective is to learn the charging patterns of plug-in electric car owners, and to study how a residential fleet of electric vehicles might strain the electric grid if all owners try to charge them at the same, which is what the preliminary monitoring found when the plug-in cars return home in the evening. The Mueller neighborhood is the test ground, and as of June 2013, the community has nearly 60 Chevrolet Volt owners alone. This cluster of Volts was achieved thanks to GM's commitment to match the federal government's $7,500 rebate incentive, which effectively halves the purchase price of the plug-hybrid electric cars.

Risks associated with noise reduction

Main article: Electric vehicle warning sounds

Electric cars and plug-in hybrids when operating in all-electric mode at low speeds produce less roadway noise as compared to vehicles propelled by an internal combustion engine, thereby reducing harmful noise health effects. However, blind people or the visually impaired consider the noise of combustion engines a helpful aid while crossing streets, hence plug-in electric cars and conventional hybrids could pose an unexpected hazard when operating at low speeds.

The 2011 Nissan Leaf had a switch to manually turn off its electric warning sound system.

Several tests conducted in the U.S. have shown that this is a valid concern, as vehicles operating in electric mode can be particularly hard to hear below 20 mph (30 km/h) for all types of road users and not only the visually impaired. At higher speeds the sound created by tire friction and the air displaced by the vehicle start to make sufficient audible noise. However, a 2011 study, commissioned by the UK Department for Transport (DfT) and conducted by the Transport Research Laboratory, found little correlation between pedestrian vehicle involvement density and noise level for the majority of vehicles. In addition, the analysis found no evidence of a pattern in pedestrian vehicle involvement densities when only considering those accidents occurring on 30 mph (48 km/h) or slower roads, or where the pedestrian was disabled. A previous study did not found an increased pedestrian vehicle involvement density for electric and hybrid vehicles with respect to their conventional counterparts which raised the question as to whether added sound is necessarily required.

Some carmakers announced they have decided to address this safety issue, and as a result, the new Nissan Leaf electric car and Chevrolet Volt plug-in hybrid, both launched in December 2010, as well as the Fisker Karma plug-in hybrid launched in 2011 launched in 2012, include electric warning sounds to alert pedestrians, the blind and others to their presence. As of January 2014, most of the hybrids and plug-in electric and hybrids available in the United States, Japan and Europe make warning noises using a speaker system. The Tesla Model S is one of the few electric cars without warning sounds, because Tesla Motors will await until regulations are enacted. Volkswagen and BMW also decided to add artificial sounds to their electric drive cars only when required by regulation.

The Japanese Ministry of Land, Infrastructure, Transport and Tourism issued guidelines for hybrid and other near-silent vehicles in January 2010. In the United States the Pedestrian Safety Enhancement Act of 2010 was approved by the U.S. Senate and the House of Representatives in December 2010. The act does not stipulate a specific speed for the simulated noise but requires the U.S. Department of Transportation to study and establish a motor vehicle safety standard that would set requirements for an alert sound. A proposed rule was published for comment by the National Highway Traffic Safety Administration (NHTSA) in January, 2013. It would require hybrids and electric vehicles traveling at less than 18.6 miles per hour (30 km/h) to emit warning sounds that pedestrians must be able to hear over background noises. According to the NHTSA proposal carmakers would be able to pick the sounds the vehicles make from a range of choices, and similar vehicles would have to make the same sounds. The rules were scheduled to go into effect in September 2014. However, in January 2015 the NHTSA rescheduled the date for a final ruling to the end of 2015. Since the regulation comes into force three years after being rendered as a final rule, compliance was delayed to 2018.

On 6 February 2013, the European Parliament approved a draft law to tighten noise limits for cars to protect public health, and also to add alerting sounds to ensure the audibility of hybrid and electric vehicles to improve the safety of vulnerable road users in urban areas, such as blind, visually and auditorily challenged pedestrians, cyclists and children. The draft legislation states a number of tests, standards and measures that must first be developed for an Acoustic Vehicle Alerting Systems (AVAS) to be compulsory in the future. The approved amendment establishes that the sound to be generated by the AVAS should be a continuous sound and should be easily indicative of vehicle behavior and should sound similar to the sound of a vehicle of the same category equipped with an internal combustion engine." In April 2014 the European Parliament approved legislation that requires the mandatory use of the AVAS for all new electric and hybrid electric vehicles and car manufacturers have to comply within 5 years.

Risks of battery fire

Main article: Plug-in electric vehicle fire incidents

Frontal crash test of a Volvo C30 DRIVe Electric to assess the safety of the battery pack.

Lithium-ion batteries may suffer thermal runaway and cell rupture if overheated or overcharged, and in extreme cases this can lead to combustion. To reduce these risks, lithium-ion battery packs contain fail-safe circuitry that shuts down the battery when its voltage is outside the safe range. When handled improperly, or if manufactured defectively, some rechargeable batteries can experience thermal runaway resulting in overheating. Especially prone to thermal runaway are lithium-ion batteries. Reports of exploding cellphones have been reported in newspapers. In 2006, batteries from Apple, HP, Toshiba, Lenovo, Dell and other notebook manufacturers were recalled because of fire and explosions. Also, during the Boeing 787 Dreamliner's first year of service, at least four aircraft suffered from electrical system problems stemming from its lithium-ion batteries, resulting in the whole Dreamliner fleet being voluntarily grounded in January 2013.

Several plug-in electric vehicle fire incidents have taken place since the introduction of mass-production plug-in electric vehicles in 2008. Most of them have been thermal runaway incidents related to the lithium-ion batteries and have involved the Zotye M300 EV, Chevrolet Volt, Fisker Karma, BYD e6, Dodge Ram 1500 Plug-in Hybrid, Toyota Prius Plug-in Hybrid, Mitsubishi i-MiEV and Outlander P-HEV. As of November 2013, four fires after a crash have been reported associated with the batteries of all-electric cars involving a BYD e6 and three Tesla Model S cars.

The first modern crash-related fire was reported in China in May 2012, after a high-speed car crashed into a BYD e6 taxi in Shenzhen. The second reported incident occurred in the United States on October 1, 2013, when a Tesla Model S caught fire after the electric car hit metal debris on a highway in Kent, Washington state, and the debris punctured one of 16 modules within the battery pack. A second reported fire occurred on October 18, 2013 in Merida, Mexico. In this case the vehicle was being driven at high speed through a roundabout and crashed through a wall and into a tree. On November 6, 2013, a Tesla Model S being driven on Interstate 24 near Murfreesboro, Tennessee caught fire after it struck a tow hitch on the roadway, causing damage beneath the vehicle.

The U.S. National Highway Traffic Safety Administration (NHTSA) is conducting a study due in 2014 to establish whether lithium-ion batteries in plug-electric vehicles pose a potential fire hazard. The research is looking at whether the high-voltage batteries can cause fires when they are being charged and when the vehicles are involved in an accident. Both General Motors and Nissan have published a guide for firefighters and first responders to properly handle a crashed plug-in electric-drive vehicle and safely disable its battery and other high voltage systems.

Rare earth metals availability and supply security

Common technology for plug-ins and electric cars is based on the lithium-ion battery and an electric motor which uses rare earth elements. The demand for lithium, heavy metals, and other specific elements (such as neodymium, boron and cobalt) required for the batteries and powertrain is expected to grow significantly due to the future sales increase of plug-in electric vehicles in the mid and long term. As of 2011, the Toyota Prius battery contains more than 20 lb (9.1 kg) of the rare earth element lanthanum, and its motor magnets use neodymium and dysprosium. While only 0.25 oz (7 g) of lithium carbonate equivalent (LCE) are required in a smartphone and 1.1 oz (30 g) in a tablet computer, electric vehicles and stationary energy storage systems for homes, businesses or industry use much more lithium in their batteries. As of 2016 a hybrid electric passenger car might use 11 lb (5 kg) of LCE, while one of Tesla's high performance electric cars could use as much as 180 lb (80 kg).

Some of the largest world reserves of lithium and other rare metals are located in countries with strong resource nationalism, unstable governments or hostility to U.S. interests, raising concerns about the risk of replacing dependence on foreign oil with a new dependence on hostile countries to supply strategic materials.

Lithium

The Salar de Uyuni in Bolivia is one of the largest known lithium reserves in the world.

The main deposits of lithium are found in China and throughout the Andes mountain chain in South America. In 2008 Chile was the leading lithium metal producer with almost 30%, followed by China, Argentina, and Australia. In the United States lithium is recovered from brine pools in Nevada.

Nearly half the world's known reserves are located in Bolivia, and according to the US Geological Survey, Bolivia's Salar de Uyuni desert has 5.4 million tons of lithium. Other important reserves are located in Chile, China, and Brazil. Since 2006 the Bolivian government have nationalized oil and gas projects and is keeping a tight control over mining its lithium reserves. Already the Japanese and South Korean governments, as well as companies from these two countries and France, have offered technical assistance to develop Bolivia's lithium reserves and are seeking to gain access to the lithium resources through a mining and industrialization model suitable to Bolivian interests.

According to a 2011 study conducted at Lawrence Berkeley National Laboratory and the University of California Berkeley, the currently estimated reserve base of lithium should not be a limiting factor for large-scale battery production for electric vehicles, as the study estimated that on the order of 1 billion 40 kWh Li-based batteries (about 10 kg of lithium per car) could be built with current reserves, as estimated by the U.S. Geological Survey. Another 2011 study by researchers from the University of Michigan and Ford Motor Company found that there are sufficient lithium resources to support global demand until 2100, including the lithium required for the potential widespread use of hybrid electric, plug-in hybrid electric and battery electric vehicles. The study estimated global lithium reserves at 39 million tons, and total demand for lithium during the 90-year period analyzed at 12–20 million tons, depending on the scenarios regarding economic growth and recycling rates.

A 2016 study by Bloomberg New Energy Finance (BNEF) found that availability of lithium and other finite materials used in the battery packs will not be a limiting factor for the adoption of electric vehicles. BNEF estimated that battery packs will require less than 1% of the known reserves of lithium, nickel, manganese, and copper through 2030, and 4% of the world’s cobalt. After 2030, the study states that new battery chemistries will probably shift to other source materials, making packs lighter, smaller, and cheaper.

Rare earth elements

China has 48% of the world's reserves of rare earth elements, the United States has 13%, and Russia, Australia, and Canada have significant deposits. Until the 1980s, the U.S. led the world in rare earth production, but since the mid-1990s China has controlled the world market for these elements. The mines in Bayan Obo near Baotou, Inner Mongolia, are currently the largest source of rare earth metals and are 80% of China's production. In 2010 China accounted for 97% of the global production of 17 rare earth elements. Since 2006 the Chinese government has been imposing export quotas reducing supply at a rate of 5% to 10% a year.

Prices of several rare earth elements increased sharply by mid-2010 as China imposed a 40% export reduction, citing environmental concerns as the reason for the export restrictions. These quotas have been interpreted as an attempt to control the supply of rare earths. However, the high prices have provided an incentive to begin or reactivate several rare earth mining projects around the world, including the United States, Australia, Vietnam, and Kazakhstan.

Evolution of global rare earth oxides production by country (1950–2000)

In September 2010, China temporarily blocked all exports of rare earths to Japan in the midst of a diplomatic dispute between the two countries. These minerals are used in hybrid cars and other products such wind turbines and guided missiles, thereby augmenting the worries about the dependence on Chinese rare earth elements and the need for geographic diversity of supply. A December 2010 report published by the US DoE found that the American economy vulnerable to rare earth shortages and estimates that it could take 15 years to overcome dependence on Chinese supplies. China raised export taxes for some rare earths from 15 to 25%, and also extended taxes to exports of some rare earth alloys that were not taxed before. The Chinese government also announced further reductions on its export quotas for the first months of 2011, which represent a 35% reduction in tonnage as compared to exports during the first half of 2010.

On September 29, 2010, the U.S. House of Representatives approved the Rare Earths and Critical Materials Revitalization Act of 2010 (H.R.6160). The approved legislation is aimed at restoring the U.S. as a leading producer of rare earth elements, and would support activities in the U.S. Department of Energy (US DoE) to discover and develop rare earth sites inside of the U.S. in an effort to reduce the auto industry's near-complete dependence on China for the minerals. A similar bill, the Rare Earths Supply Technology and Resources Transformation Act of 2010 (S. 3521), is being discussed in the U.S. Senate.

In order to avoid its dependence on rare earth minerals, Toyota Motor Corporation announced in January 2011 that it is developing an alternative motor for future hybrid and electric cars that does not need rare earth materials. Toyota engineers in Japan and the U.S. are developing an induction motor that is lighter and more efficient than the magnet-type motor used in the Prius, which uses two rare earths in its motor magnets. Other popular hybrids and plug-in electric cars in the market that use these rare earth elements are the Nissan Leaf, the Chevrolet Volt and Honda Insight. For its second generation RAV4 EV due in 2012, Toyota is using an induction motor supplied by Tesla Motors that does not require rare earth materials. The Tesla Roadster and the Tesla Model S use a similar motor.

Car dealers reluctance to sell

With the exception of Tesla Motors, almost all new cars in the United States are sold through dealerships, so they play a crucial role in the sales of electric vehicles, and negative attitudes can hinder early adoption of plug-in electric vehicles. Dealers decide which cars they want to stock, and a salesperson can have a big impact on how someone feels about a prospective purchase. Sales people have ample knowledge of internal combustion cars while they do not have time to learn about a technology that represents a fraction of overall sales. As with any new technology, and in the particular case of advanced technology vehicles, retailers are central to ensuring that buyers, especially those switching to a new technology, have the information and support they need to gain the full benefits of adopting this new technology.

Car dealerships play a crucial role in the sales of plug-in electric vehicles. Shown a dealership exhibiting first generation Chevrolet Volts.

There are several reasons for the reluctance of some dealers to sell plug-in electric vehicles. PEVs do not offer car dealers the same profits as gasoline-powered car. Plug-in electric vehicles take more time to sell because of the explaining required, which hurts overall sales and sales people commissions. Electric vehicles also may require less maintenance, resulting in loss of service revenue, and thus undermining the biggest source of dealer profits, their service departments. According to the National Automobile Dealers Association (NADS), dealers on average make three times as much profit from service as they do from new car sales. However, a NADS spokesman said there was not sufficient data to prove that electric cars would require less maintenance. According to the New York Times, BMW and Nissan are among the companies whose dealers tend to be more enthusiastic and informed, but only about 10% of dealers are knowledgeable on the new technology.

A study conducted at the Institute of Transportation Studies (ITS), at the University of California, Davis (UC Davis) published in 2014 found that many car dealers are less than enthusiastic about plug-in vehicles. ITS conducted 43 interviews with six automakers and 20 new car dealers selling plug-in vehicles in California’s major metro markets. The study also analyzed national and state-level J.D. Power 2013 Sales Satisfaction Index (SSI) study data on customer satisfaction with new car dealerships and Tesla retail stores. The researchers found that buyers of plug-in electric vehicles were significantly less satisfied and rated the dealer purchase experience much lower than buyers of non-premium conventional cars, while Tesla Motors earned industry-high scores. According to the findings, plug-in buyers expect more from dealers than conventional buyers, including product knowledge and support that extends beyond traditional offerings.

In 2014 Consumer Reports published results from a survey conducted with 19 secret shoppers that went to 85 dealerships in four states, making anonymous visits between December 2013 and March 2014. The secret shoppers asked a number of specific questions about cars to test the salespeople’s knowledge about electric cars. The consumer magazine decided to conduct the survey after several consumers who wanted to buy a plug-in car reported to the organization that some dealerships were steering them toward gasoline-powered models. The survey found that not all sales people seemed enthusiastic about making PEV sales; a few outright discouraged it, and even one dealer was reluctant to even show a plug-in model despite having one in stock. And many sales people seemed not to have a good understanding of electric-car tax breaks and other incentives or of charging needs and costs. Consumer Reports also found that when it came to answering basic questions, sales people at Chevrolet, Ford, and Nissan dealerships tended to be better informed than those at Honda and Toyota. The survey found that most of the Toyota dealerships visited recommended against buying a Prius Plug-in and suggested buying a standard Prius hybrid instead. Overall, the secret shoppers reported that only 13 dealers “discouraged sale of EV,” with seven of them being in New York. However, at 35 of the 85 dealerships visited, the secret shoppers said sales people recommended buying a gasoline-powered car instead.

The ITS-Davis study also found that a small but influential minority of dealers have introduced new approaches to better meet the needs of plug-in customers. Examples include marketing carpool lane stickers, enrolling buyers in charging networks, and preparing incentive paperwork for customers. Some dealers assign seasoned sales people as plug-in experts, many of whom drive plug-ins themselves to learn and be familiar with the technology and relate the car’s benefits to potential buyers. The study concluded also that carmakers could do much more to support dealers selling PEVs.

Government incentives

Main article: Government incentives for plug-in electric vehicles

Several national and local governments around the world have established tax credits, grants and other financial and non-financial incentives for consumers to purchase a plug-in electric vehicle as a policy to promote the introduction and mass market adoption of this type of vehicles.

Asia

The Nissan Leaf electric car is eligible for government incentives for plug-in electric vehicles in Japan, the United States and several European countries.

Japan

In May 2009 the Japanese Diet passed the "Green Vehicle Purchasing Promotion Measure" that went into effect on June 19, 2009, but retroactive to April 10, 2009. The program established tax deductions and exemptions for environmentally friendly and fuel efficient vehicles, according to a set of stipulated environmental performance criteria, and the requirements are applied equally to both foreign and domestically produced vehicles. The program provides purchasing subsidies for two type of cases, consumers purchasing a new passenger car without trade-in (non-replacement program), and for those consumers buying a new car trading an used car registered 13 years ago or earlier (scrappage program).

China

On June 1, 2010, The Chinese government announced a trial program to provide incentives up to 60,000 yuan (~US$8,785) for private purchase of new battery electric vehicles and 50,000 yuan (~US$7,320) for plug-in hybrids in five cities.

Europe

As of 2010, 17 of the 27 European Union member states provide tax incentives for electrically chargeable vehicles. The incentives consist of tax reductions and exemptions, as well as of bonus payments for buyers of PEVs and hybrid vehicles.

In the UK the Plug-in Car Grant scheme provided a 25% incentive towards the cost of new plug-in electric cars that qualify as ultra-low carbon vehicles, capped at £5,000 (US$7,800) until February 2016. Both private and business fleet buyers are eligible for the government grant. In December 2015, the Department for Transport (DfT) announced that Plug-in car grant was extended to encourage more than 100,000 UK motorists to buy cleaner vehicles. The criteria for the Plug-in Car Grant was updated and the maximum grant dropped from £5,000 (~US$7,450) to £4,500 (~US$6,700). The eligible ultra-low emission vehicles (ULEVs) must meet criteria in one of three categories depending on emission levels (CO₂ emissions bands between 50 and 75g/km) and zero-emission-capable mileage (minimum of 10 mi (16 km)).

Both in the UK and Germany, the Tesla Model S, and other premium plug-in cars are not eligible to the purchase incentives because both countries set a cap on the purchase price.

A price cap is in place, with all Category 1 plug-in vehicles eligible for the full grant no matter what their purchase price, while Category 2 and 3 models with a list price of more than £60,000 (~US$90,000) will not be eligible for the grant. Vehicles with a zero-emission range of at least 70 miles (110 km) (category 1), including hydrogen fuel cell vehicles, will get a full £4,500 (~US$6,700), but plug-in hybrids (categories 2 and 3) costing under £60,000 (~US$90,000) will receive £2,500 (~US$3,725). Under the extended scheme, some plug-in hybrid sports car will no longer be eligible for the grant, such as the BMW i8 because of its £100,000 (~US$150,000) purchase price tag. The updated scheme came into force on 1 March 2016.

Germany approved an incentive scheme in April 2016 with a budget of €1 billion (US$1.13 billion). The cost of the purchase incentive is shared equally between the government and automakers. Electric car buyers get a €4000 (US$4,520) discount while buyers of plug-in hybrid vehicles get a discount of €3000 (US$3,390). Premium cars, such as the Tesla Model S and BMW i8, are not eligible to the incentive because there is a cap of €60,000 (US$67,800) for the purchase price. Only electric vehicles purchased after 18 May 2016 are eligible for the bonus and the owner must keep the new electric car at least nine months. The same rule applies for leasing. The online application system to claim the bonus went into effect on 2 July 2016. As of September 2016, BMW, Citroën, Daimler, Ford, Hyundai, Kia, Mitsubishi, Nissan, Peugeot, Renault, Toyota, Volkswagen, and Volvo had signed up to participate in the scheme.

In the United States the Energy Improvement and Extension Act of 2008, and later the American Clean Energy and Security Act of 2009 (ACES) granted tax credits for new qualified plug-in electric vehicles. The American Recovery and Reinvestment Act of 2009 (ARRA) also authorized federal tax credits for converted plug-ins, though the credit is lower than for new PEVs.

The federal tax credit for new plug-in electric vehicles is worth $2,500 plus $417 for each kilowatt-hour of battery capacity over 5 kWh, and the portion of the credit determined by battery capacity cannot exceed $5,000. Therefore, the total amount of the credit allowed for a new PEV is $7,500. Several states have established incentives and tax exemptions for BEVs and PHEV, and other non-monetary incentives.

President Barack Obama set the goal of bringing 1 million plug-in electric vehicles on the road by 2015. However, considering the actual slow rate of PEV sales, as of mid-2012 several industry observers have concluded that this goal is unattainable. In September 2014 Governor of California Jerry Brown signed a bill, the Charge Ahead California Initiative, that sets a goal of placing at least 1 million zero-emission vehicles and near-zero-emission vehicles on the road in California by January 1, 2023.

Canada

Ontario established a rebate between CA$5,000 to CA$8,500 (~US$4,900 to US$8,320), depending on battery size, for purchasing or leasing a new plug-in electric vehicle after July 1, 2010. The rebates are available to the first 10,000 applicants who qualify.

Quebec offers rebates of up to CA$8,500 (US$8,485) from January 1, 2012, for the purchase of new plug-in electric vehicles equipped with a minimum of 4 kWh battery, and new hybrid electric vehicles are eligible for a CA$1,000 rebate. All-electric vehicles with high-capacity battery packs are eligible for the full C$8,000 rebate, and incentives are reduced for low-range electric cars and plug-in hybrids.

Production plug-in electric vehicles available

See also: List of modern production plug-in electric vehicles and electric car use by country

The General Motors EV1 was the first mass-produced and purpose-designed all-electric car of the modern era from a major automaker.

During the 1990s several highway-capable plug-in electric cars were produced in limited quantities, all were battery electric vehicles, and they were available through leasing mainly in California. Popular models included the General Motors EV1 and the Toyota RAV4 EV. Some of the latter were sold to the public and are in use still today. In the late 2000s began a new wave of mass production plug-in electric cars, motorcycles and light trucks. However, as of 2011, most electric vehicles in the world roads were low-speed, low-range neighborhood electric vehicles (NEVs) or electric quadricycles. Pike Research estimated there were almost 479,000 NEVs on the world roads in 2011. Just in China, a total of 200,000 low-speed small electric cars were sold in 2013, most of which are powered by lead-acid batteries. An additional 600,000 low-speed small electric passenger vehicles were sold in China in 2015. As of October 2015, the GEM neighborhood electric vehicle is the market leader in North America, with global sales of more than 50,000 units since 1998.

As of August 2015, there were almost 70 models of highway-capable plug-in electric passenger cars and light-utility vans available in the world, with 45 different plug-in electric passenger car models offered in Europe, 20 available in North America, 19 in China, 14 in Japan, and 7 in Australia. There are also available several commercial models of plug-in motorcycles, all-electric buses, and heavy-duty trucks.

The Renault-Nissan Alliance is the world's leading all-electric vehicle manufacturer. The Alliance achieved the sales milestone of 350,000 all-electric vehicles delivered globally in August 2016. Nissan global electric vehicle sales passed the 250,000 unit milestone also in August 2016. Renault global electric vehicle sales passed the 100,000 unit milestone in September 2016.

Tesla Motors is the world's second largest plug-in electric vehicle manufacturer with almost 164,000 electric cars sold between 2008 and September 2016. Mitsubishi Motors ranks third, with global sales of over 152,000 plug-in electric vehicles since 2009 through August 2016, consisting of all-electric cars of the Mitsubishi i-MiEV family, all-electric Mitsubishi Minicab MiEV utility vans and trucks, and the plug-in hybrid Mitsubishi Outlander P-HEV. Next is General Motors with combined global sales since December 2010 of almost 113,000 vehicles through December 2015, consisting of over 106,000 plug-in hybrids of the Volt/Ampera family, over 4,300 Chevrolet Spark EVs, and over 2,400 Cadillac ELRs.

BYD Auto ended 2015 as the world's best selling manufacturer of highway legal light-duty plug-in electric vehicles, with 61,722 units sold, mostly plug-in hybrids, followed by Tesla Motors, with 50,580 units sold in 2015. During the first half of 2016, BYD continued as the world's top selling plug-in car manufacturer with over 43,000 units sold, and again, followed by Tesla with over 29,000 units delivered.

Sales and main markets

Detroit Electric car charging in 1919. During the Golden Age of the electric car at the beginning of the 20th century, the EV stock peaked at about 30,000 vehicles.

By mid-September 2015, the global stock of highway legal plug-in electric passenger cars and utility vans passed the one million sales milestone. Sales of plug-in electric vehicles achieved the one million milestone almost twice as fast as hybrid electric vehicles (HEV). While it took four years and 10 months to reach one-million PEV sales, it took more than around nine years and a few months for HEVs to reach its first million sales. When global sales are broken down by type of powertrain, all-electric cars have oversold plug-in hybrids, with pure electrics capturing 58.9% of the global stock of 1.257 million plug-ins on the world's roads by the end of 2015. The global ratio between all-electrics (BEVs) and plug-in hybrids (PHEVs) has consistently been 60:40 between 2014 and the first half of 2016, mainly due to the large all-electric market in China. In the U.S. and Europe, the ratio is approaching a 50:50 split.

The global stock of plug-in electric vehicles between 2005 and 2009 consisted exclusively of all-electric cars, totaling about 1,700 units in 2005, and almost 6,000 in 2009. The plug-in stock rose to about 12,500 units in 2010, of which, only 350 vehicles were plug-in hybrids. By comparison, during the Golden Age of the electric car at the beginning of the 20th century, the EV stock peaked at approximately 30,000 vehicles. After the introduction of the Nissan Leaf and the Chevrolet Volt in late December 2010, the first mass-production plug-in cars by major carmakers, plug-in car sales grew to about 50,000 units in 2011, jumped to 125,000 in 2012, and rose to almost 213,000 plug-in electric cars and utility vans in 2013. Sales totaled over 315,000 units in 2014, up 48% from 2013.

In five years, global sales of highway legal light-duty plug-in electric vehicles have increased more than ten-fold, totaling more than 565,000 units in 2015. Plug-in sales in 2015 increased about 80% from 2014, driven mainly by China and Europe. Both markets passed in 2105 the U.S. as the largest plug-in electric car markets in terms of total annual sales, with China ranking as the world's best-selling plug-in electric passenger car country market in 2015. About 307,000 plug-in cars and vans were sold during the first half of 2016. Since 2004, cumulative global sales totaled over 1.5 million plug-in cars and utility vans by the end of May 2016. Despite the rapid growth experienced, the plug-in electric car segment represented just 0.1% of the one billion cars on the world's roads by the end of 2015.

Main article: Plug-in electric vehicles in Norway

Registration of plug-in electric vehicles in Norway by year between 2004 and 2015. Includes plug-in hybrids and all-electric cars and vans. Used imports are included.

As of September 2016, a total of 121,330 light-duty plug-in electric vehicles have been registered in Norway, making the country the largest European plug-in market and the fourth largest in the world. Accounting for registrations of both new car sales and used imports, as of September 2016, the Norwegian light-duty plug-in electric fleet consist of 92,813 all-electric passenger cars, 26,225 plug-in hybrids, and 2,292 all-electric vans.

The government's target of 50,000 all-electric cars on Norwegian roads was reached in April 2015, more than two years earlier than expected, thanks to the successful policies implemented to promote electric vehicle adoption that include fiscal and non-monetary incentives. The milestone of 100,000 light-duty plug-in electric vehicles registered was achieved in April 2016.

The Norwegian fleet of electric cars is one of the cleanest in the world because 98% of the electricity generated in the country comes from hydropower. Norway, with about 5.2 million people, is the country with the largest EV ownweship per capita in the world. In March 2014, Norway became the first country where over one in every 100 registered passenger cars is plug-in electric. The segment's market penetration reached 2% in March 2015, and passed 3% in December 2015. With about 90,000 pure electric vehicles registered by mid-September 2016, the all-electric segment achieved a market penetration of 3.5% of all passenger cars on Norwegians roads.

Netherlands

Main article: Plug-in electric vehicles in the Netherlands

Registration of highway-capable plug-in electric vehicles in the Netherlands by year between 2010 and 2015.

A total of 98,295 highway legal light-duty plug-in electric vehicles were registered in the Netherlands at the end of September 2016, consisting of 84,730 range-extended and plug-in hybrids, 11,986 pure electric cars, and 1,579 all-electric light utility vans. When buses, trucks, motorcycles, quadricycles and tricycles are accounted for, the Dutch plug-in electric-drive fleet climbs to 99,763 units. The Netherlands listed as the world's third best-selling country market for light-duty plug-in vehicles in 2015, with 43,971 units registered that year. Until December 2015, the Netherlands had Europe's largest fleet light-duty plug-in vehicles. Plug-in sales fell sharply during 2016, and as a result, by early October 2016, the Netherlands listed as the third largest European plug-in market, after being surpassed during the year by both Norway and France. As of July 2016, the Netherlands had the second largest plug-in market concentration per capita in the world after Norway.

Registrations of plug-in electric car represented a 0.57% share of total new car registrations in the country during 2011 and 2012. During 2013 plug-in electric passenger car registrations totaled 22,415 units, climbing 338% from 2012, the highest rate of growth of any country in the world in 2013. The segment's market share surged almost ten times from 2012 to 5.37% new car sales in the country during that year, the world's second highest in 2013 after Norway (5.6%). The rapid growth of segment during 2013, allowed the Netherlands to reach a plug-in vehicle concentration of around 1.71 vehicles registered per 1,000 people, second only to Norway (4.04). As of July 2016, the plug-in concentration had risen to 5.6 per 1,000 people. The market share of the plug-in electric passenger car segment in 2014 fell to 3.86% of total new passenger car registrations, after the end of some of the tax incentives. With 43,769 plug-in passenger cars registered in 2015, the segment market share rose to a record 9.7% of new car sales in the Dutch market in 2015, the second highest after Norway (22.4%).

As of September 2016, the Mitsubishi Outlander P-HEV is the all-time top selling plug-in electric vehicle in the Netherlands, with 24,765 units registered.

In November 2013, a total of 2,736 Mitsubishi Outlander P-HEVs were sold, making the plug-in hybrid the top selling new car in the country that month, representing a market share of 6.8% of all the new cars sold. Again in December 2013, the Outlander P-HEV ranked as the top selling new car in the country with 4,976 units, representing a 12.6% market share of new car sales, contributing to a world record plug-in vehicle market share of 23.8% of new car sales. The Netherlands is the second country, after Norway, where plug-in electric cars have topped the monthly ranking of new car sales. The strong increase of plug-in car sles during the last months of 2013 was due to the end of the total exemption of the registration fee for corporate cars, which is valid for 5 years. From January 1, 2014, all-electric vehicles pay a 4% registration fee and plug-in hybrids a 7% fee.

The top 5 best-selling plug-in electric cars in 2015 were all plug-in hybrids, led by the Mitsubishi Outlander P-HEV (8,757). The top selling all-electric car was the Tesla Model S (1,842). Plug-in car sales achieved its best monthly volume on record ever in December 2015, with about 15,900 units sold, and allowing the segment to reach a record market share of about 23%. The surge in plug-in car sales was due to reduction of the registration fees for plug-in hybrids. From January 1, 2016, all-electric vehicles continue to pay a 4% registration fee, but for a plug-in hybrid the fee rises from 7% to 15% if its CO₂ emissions do not exceed 50 g/km. The rate for a conventional internal combustion car is 25% of its book value.

As a result of the changes in the tax rules that went into force at the beginning of 2016, plug-in electric car sales declined significantly. Sales during the first half of 2016 were down 64% from the same period in 2015. A total of 9,185 plug-in passenger cars were registered in the first three quarters of 2016, consisting of 6,567 plug-in hybrids and 2,618 all-electric cars. The market share of the plug-in car segment captured 3.2% of new car sales during the period. As of September 2016, the Outlander P-HEV remained as the all-time top-selling plug-in car in the country with 24,765 units registered. Ranking second is the Volvo V60 Plug-in Hybrid (14,917), followed by the Volkswagen Golf GTE (9,530), Tesla Model S (5,622), and Audi A3 e-tron (5,098).

Quebec is the regional market leader in Canada, with about 11,000 plug-in electric cars registered as of September 2016, of which, 55% are plug-in hybrids. Registrations in the province totaled 3,100 units in 2015, representing a market share of 0.7% of new car sales, and 45% of total Canadian plug-in electric car sales that year. In October 2016, the National Assembly of Quebec passed a new zero emission vehicle legislation that obliges major automakers selling cars in the Canadian province to offer their customers a minimum number of plug-in hybrid and all-electric models. Under the new law, 3.5% of the total number of autos sold by carmakers in Quebec have to be zero emissions vehicles starting in 2018, rising to 15.5% in 2020. A tradable credit system was created for those carmakers not fulfilling their quotas to avoid financial penalties. Quebec aims to have 100,000 zero emission vehicles on the road by 2020.

As of December 2015, there were 18,451 highway legal plug-in electric cars registered in Canada, consisting of 10,034 (54%) all-electric cars and 8,417 (46%) plug-in hybrids. Until 2014 Canadian sales were evenly split between all-electric cars (50.8)% and plug-in hybrids (49.2%). The Model S was the top selling plug-in electric car in Canada in 2015 with 2,010 units sold. The Chevrolet Volt, with 2,544 units sold, ranked as the top selling plug-in car during the first three quarters of 2016.
