Nissan Leaf, the world's top selling highway-capable all-electric car ever, with global sales of over 150,000 units by November 2014.[1]

A battery electric vehicle (BEV) is a type of electric vehicle (EV) that uses chemical energy stored in rechargeable battery packs. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion.

A battery-only electric vehicle or all-electric vehicle derives all its power from its battery packs and thus has no internal combustion engine, fuel cell, or fuel tank. BEVs include bicycles, scooters, rail cars, forklifts, buses, trucks and cars. Since the introduction of the all-electric Nissan Leaf in December 2010, over 600,000 highway legal plug-in electric vehicles have been sold worldwide by September 2014, of which more than 356,000 are all-electric passenger cars and light-duty trucks.[2] The best-selling all-electric car ever, the Nissan Leaf, has sold over 150,000 units worldwide by November 2014.[1]

Terminology[edit]

Vehicles using both electric motors and internal combustion engines are examples of hybrid electric vehicles, and are not considered pure or all-electric vehicles because they cannot be externally charged (operate in charge-sustaining mode) and instead they are continually recharged with power from the internal combustion engine and regenerative braking.[3]

Hybrid vehicles with batteries that can be charged externally to displace some or all of their internal combustion engine power and gasoline fuel are called plug-in hybrid electric vehicles (PHEV), and run as BEVs during their charge-depleting mode. PHEVs with a series powertrain are also called range-extended electric vehicles (REEVs), such as the Chevrolet Volt and Fisker Karma.

Plug-in electric vehicles (PEVs) are 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.[3][4]

In China, plug-in electric vehicles, together with hybrid electric vehicles are called new energy vehicles (NEVs).[5] However, in the United States, neighborhood electric vehicles (NEVs) are battery electric vehicles that are legally limited to roads with posted speed limits no higher than 45 miles per hour (72 km/h), are usually built to have a top speed of 30 miles per hour (48 km/h), and have a maximum loaded weight of 3,000 lbs.[6]

Vehicles by type[edit]

The concept of battery electric vehicles is to use charged batteries on board vehicles for propulsion. Battery electric cars are becoming more and more attractive with the advancement of new battery technology (Lithium Ion) that have higher power and energy density (i.e. greater possible acceleration and more range with fewer batteries) and higher oil prices.[7]

BEVs include automobiles, light trucks, and neighborhood electric vehicles.

Rail[edit]

Electric bus[edit]

A battery-electric minibus in St Helens, England

Chattanooga, Tennessee operates nine zero-fare electric buses, which have been in operation since 1992 and have carried 11.3 million passengers and covered a distance of 3,100,000 kilometres (1,900,000 mi), They were made locally by Advanced Vehicle Systems. Two of these buses were used for the 1996 Atlanta Olympics.[8][9]

Beginning in the summer of 2000, Hong Kong Airport began operating a 16-passenger Mitsubishi Rosa electric shuttle bus, and in the fall of 2000, New York City began testing a 66-passenger battery-powered school bus, an all electric version of the Blue Bird TC/2000.[10] A similar bus was operated in Napa Valley, California for 14 months ending in April, 2004.[11]

The 2008 Beijing Olympics used a fleet of 50 electric buses, which have a range of 130 km (81 mi) with the air conditioning on. They use Lithium-ion batteries, and consume about 1 kW·h/mi (0.62 kW·h/km; 2.2 MJ/km). The buses were designed by the Beijing Institute of Technology and built by the Jinghua Coach Co. Ltd.[12] The batteries are replaced with fully charged ones at the recharging station to allow 24-hour operation of the buses.[13]

In France, the bus electric phenomenon is in development, but we already can find some of them in operation in numerous cities of France.[14] PVI, a medium company located in the Paris region, is one of the leader of the market with its brand Gepebus (offering Oreos 2X and Oreos 4X).[15]

In the United States, the first battery-electric, fast-charge bus has been in operation in Pomona, California since September 2010 at Foothill Transit. The Proterra EcoRide BE35 uses lithium-titanate batteries and is able to fast-charge in less than 10 minutes.[16]

Thunder Sky[edit]

Thunder Sky (based in Hong Kong) builds lithium-ion batteries used in submarines and has three models of electric buses, the 10/21 passenger EV-6700 with a range of 280 km (170 mi) under 20 mins quick-charge, the EV-2009 city buses, and the 43 passenger EV-2008 highway bus, which has a range of 300 km (190 mi) under quick-charge (20 mins to 80%), and 350 km (220 mi) under full charge (25 mins). The buses will also be built in the United States and Finland.[17]

Free Tindo[edit]

Tindo is an all-electric bus from Adelaide, Australia. The Tindo (aboriginal word for sun) is made by Designline International[18] in New Zealand and gets its electricity from a solar PV system on Adelaide's central bus station. Rides are zero-fare as part of Adelaide's public transport system.[19]

First electric commercial bus[edit]

Seoul Metropolitan Government runs the world's first commercial all-electric bus service. The bus was developed by Hyundai Heavy Industries and Hankuk Fiber which make a lightweight body from carbon composite material. Provided with Li-on battery and regenerative braking, the bus may run to 52 miles (84 km) in a single 30 minutes charge. The maximum speed is 62 miles per hour (100 km/h).[20]

First Fast-Charge, Battery-Electric Transit Bus[edit]

Proterra's EcoRide BE35 transit bus, called the Ecoliner by Foothill Transit in West Covina, California, is the world’s first heavy duty, fast charge, battery-electric bus. Proterra's ProDrive drive-system uses a UQM motor and regenerative braking that captures 90% of the available energy and returns it to the TerraVolt energy storage system, which in turn increases the total distance the bus can drive by 31-35%. It can travel 30–40 miles on a single charge, is up to 600% more fuel-efficient than a typical diesel or CNG bus, and produces 44% less carbon than CNG.[21]

Electric vans[edit]

In March 2012 Smith Electric Vehicles announced the release of the Newton Step-Van, an all-electric, zero-emission vehicle built on the versatile Newton platform that features a walk-in body produced by Indiana-based Utilimaster.[22]

Electric cars[edit]

Main article: Electric car

An electric car is a plug-in battery powered automobile which is propelled by electric motor(s). Although electric cars often give good acceleration and have generally acceptable top speed, the lower specific energy of production batteries available in 2010 compared with carbon-based fuels means that electric cars need batteries that are fairly large fraction of the vehicle mass but still often give relatively low range between charges. Recharging can also take significant lengths of time. For shorter range commuter type journeys, rather than long journeys, electric cars are practical forms of transportation and can be recharged overnight.

The Tesla Model S has sold over 50,000 units worldwide by October 2014.[23]

Electric cars have the potential of significantly reducing city pollution by having zero tail pipe emissions.[24][25][26] Vehicle greenhouse gas savings depend on how the electricity is generated. With the current U.S. energy mix, using an electric car would result in a 30% reduction in carbon dioxide emissions.[27][28][29][30] Given the current energy mixes in other countries, it has been predicted that such emissions would decrease by 40% in the UK,[31] 19% in China,[32] and as little as 1% in Germany.[33][34][not in citation given]

Electric cars are expected to have a major impact in the auto industry[35][36] given advantages in city pollution, less dependence on oil, and expected rise in gasoline prices.[37][38][39] World governments are pledging billions to fund development of electric vehicles and their components. The U.S. has pledged US$2.4 billion in federal grants for electric cars and batteries.[40] China has announced it will provide US$15 billion to initiate an electric car industry.[41]

As of September 2014, more than 356,000 highway-capable all-electric passenger cars and light utility vehicles have been sold worldwide since 2008, out of total global sales of over 600,000 plug-in electric vehicles.[2] During 2012 pure electric car sales were led by Japan with a 28% market share of global sales, followed by the United States with a 26% share, China with 16%, France with 11% and Norway with 7%.[42] As of September 2014, the U.S. has the world's largest stock of all-electric cars, with 116,031 units sold since December 2010, out of about 256,000 plug-in electric cars sold in the country.[43]

The Nissan Leaf is the world's top selling highway-capable electric car ever,[44] with global sales of over 150,000 units by November 2014.[1][45] The Renault-Nissan Alliance is the leading electric vehicle manufacturer with global sales of over 200,000 all-electric vehicles delivered by November 2014.[46] Ranking second is Tesla Motors with over 52,500 electric cars sold since February 2008, including almost 2,500 Tesla Roadsters and over 50,000 Tesla Model S delivered by October 2014.[23][47] Mitsubishi Motors is the third best selling all-electric vehicle manufacturer, with global sales of over 37,000 all-electric vehicles between July 2009 and June 2014, including 32,000 cars of the Mitsubishi i-MiEV family,[48] which includes the rebadged Peugeot iOn and Citroën C-Zero sold in Europe; and over 5.600 Mitsubishi Minicab MiEV utility vans and trucks sold in Japan.[49]

Electric taxi[edit]

The first all-electric taxi, a Nissan Leaf, is circulating in Madrid, Spain.[50][dubious ]

Motors[edit]

Main article: Traction motor

Electric cars have traditionally used series wound DC motors, a form of brushed DC electric motor. Separately excited and permanent magnet are just two of the types of DC motors available. More recent electric vehicles have made use of a variety of AC motor types, as these are simpler to build and have no brushes that can wear out. These are usually induction motors or brushless AC electric motors which use permanent magnets. There are several variations of the permanent magnet motor which offer simpler drive schemes and/or lower cost including the brushless DC electric motor.

Motor controllers[edit]

Main article: Motor controller

The motor controller regulates the power to the motor, supplying either variable pulse width DC or variable frequency variable amplitude AC, depending on the motor type, DC or AC.
