Jump to: navigation, search
The BYD F3DM is the world's first mass produced plug-in hybrid passenger car, launched in China for fleet sales in December 2008.
As of October 2012, the Chevrolet Volt family is the world's top selling plug-in hybrid electric car, with global sales of more than 33,000 units.

The history of plug-in hybrid electric vehicles (PHEVs) spans a little more than a century, but most of the significant commercial developments have taken place after 2002. The revival of interest in this automotive technology together with all-electric cars is due to advances in battery and power management technologies, and concerns about increasingly volatile oil prices and supply disruption, and also the need to reduce greenhouse gas emissions.[1][2][3]

Between 2003 and 2010 most PHEVs on the roads were conversions of production hybrid electric vehicles, and the most prominent PHEVs were aftermarket conversions of 2004 or later Toyota Prius, which have had plug-in charging and more lead-acid batteries added and their electric-only range extended. As of May 2013, there are seven mass-production highway-capable plug-in hybrids available in several international markets, the Chevrolet Volt and its siblings Opel/Vauxhall Ampera and Holden Volt, Prius Plug-in Hybrid, Fisker Karma, Ford C-Max Energi, Volvo V60 Plug-in Hybrid, Honda Accord Plug-in Hybrid, Mitsubishi Outlander P-HEV, and Ford Fusion Energi.

Since the inception of the BYD F3DM in December 2008, more than 92,000 highway-capable plug-in hybrid electric cars have been sold worldwide through April 2013. The Volt/Ampera family is the world's best selling plug-in hybrid with more than 45,000 units sold through April 2013 in the United States, Canada, the Netherlands, Germany, and other European countries. The Toyota Prius PHV is the second top selling plug-in hybrid more than 33,300 units sold in Japan, the U.S. and Europe through April 2013. Ranking third is the Mitsubishi Outlander P-HEV, with more than 4,300 units sold in Japan through March 2013, closely followed by the C-Max Energi with 3,951 units sold in the U.S. through April 2013.

The leading regional market is the United States, with 32,598 Volts and 13,624 Prius PHVs sold through January 2013, followed by Japan with 9,500 Prius PHVs sold through October 2012. The third best selling market is the Netherlands with more than 3,700 PHEVs sold through December 2012, including 2,704 Opel Amperas, 610 Prius PHVs, 313 Volts and 140 Karmas. The Chevrolet Volt is the best selling plug-in electric vehicle in the U.S., outselling the all-electric Nissan Leaf by more than 12,000 units by January 2013.


Hybrid vehicles were produced beginning as early as 1899 by Lohner-Porsche. Early hybrids could be charged from an external source before operation. However, the term "plug-in hybrid" has come to mean a hybrid vehicle that can be charged from a standard electrical wall socket.

The Lohner-Porsche Mixte Hybrid was the first gasoline-electric hybridautomobile.

The July 1969 issue of Popular Science magazine featured an article on the General Motors XP-883 plug-in hybrid. The concept commuter vehicle housed six 12-volt lead acid batteries in the trunk area and a transverse-mounted DC electric motor turning a front-wheel drive trans-axle. The gasoline powered engine was connected to the trans-axle via a worm gear.[4] The car could be plugged into a standard 110 Volt AC outlet for recharging.

In 1971, Dr. Andy Frank, the inventor of the modern PHEV, begins working on hybrids and PHEVs. He is professor of Mechanical and Aeronautical Engineering at the University of California at Davis.[5]

The September 1975 issue of Popular Mechanics magazine featured a cover story on an experimental "turbo-electric" hybrid that "plugs in overnight for thrifty driving around town."[6] Built by electronics engineer Harry Grepke, the vehicle used eight 12-volt truck batteries and a turbine genset. Grepke claimed an all-electric range of 50 miles (80 km).[7]

In 1989, Audi produced its first iteration of the Audi Duo, a plug-in parallel hybrid based on the Audi 100 Avant Quattro. This car had a 12.6 bhp (9.4 kW) Siemens electric motor which drove the rear wheels. A trunk-mounted nickel-cadmium battery supplied energy to the motor that drove the rear wheels. The vehicle's front wheels were powered by a 2.3-litre five-cylinder engine with an output of 136 bhp (101 kW). The intent was to produce a vehicle which could operate on the engine in the country and electric mode in the city. Mode of operation could be selected by the driver. Just ten vehicles are believed to have been made; one drawback was that due to the extra weight of the electric drive, the vehicles were less efficient when running on their engines alone than standard Audi 100s with the same engine.

Beginning around 1990, Professor Andy Frank of the University of California, Davis began using student teams to build operational prototype Plug-in hybrid electric vehicles. His work attracted industry support and funding from Nissan, Koyo Seiko, General Motors, Saturn, Ford, Visteon, JATCO, Ovonics, the Defense Advanced Research Project Agency (DARPA), Sacramento Municipal Utility District, Southern California Edison, the United States Department of Energy, and others. The UC Davis PHEVs won several DOE/USCAR "Future Car" and "Future Truck" national competitions.

Inspired by his work as an EV1 propulsion system engineer, Jeff Ronning began developing concepts for plug-in hybrids in the mid-1990s at then Delco Remy, Division of GM. EV1 prototypes were sometimes attached with "range-extender" trailers, developed by Alan Cocconi of AC Propulsion. These trailers were simply rolling gen sets that could supply power for long trips. It was only natural to conceive of an EV1 with a small turbo-alternator on board (1995 internal publication). External publications (SAE 971629[8] and 1999-01-2946) followed expounding the merits of using electrical energy for most local travel and proving it with the data from the US DOT. "Unlimited EV" and "Battery Dominant Hybrid" as well as "Energy Hybrid" were the given names for the architecture because the term "plug-in" hybrid coined by Dr. Andy Frank was considered at odds with Toyota's position that Prius did not need to be "plugged in" and their opinion that plugging was inconvenient. In 1997 (ten years before Volt) an internal project at the new spin-off, Delphi Corporation, began to convert an EV1 to a PHEV. However, the project was canceled by the corporate directors of technology.

In 1994, the Esoro H301 two-door, four passenger plug-in hybrid sedan was built in Switzerland by the vehicle prototyping company Esoro AG.[9] Four such prototypes are still on the road. The lightweight (710 kg/1565 lb) vehicle featured a 360 cc engine in parallel with a 34 kW air-cooled AC induction motor. The 9 kWh nickel-cadmium battery could be recharged in four hours from a 220v electrical wall outlet, or from 30% to 80% state of charge in about two hours at a steady speed of 120 km/h.[10]

In 1998, Audi premiered a second iteration of the Duo plug-in hybrid, based on the Audi A4, at the Frankfurt Motor Show. The 1998 Audi Duo featured a parallel configuration similar to its predecessor. At the time, hybrid propulsion was considered as a promising solution to Europe's inner city emissions problems. Audi AG leased ten Duo PHEVs to Solarmobilverein Erlangen in the city of Erlangen, Bavaria as part of ELCIDIS (Electric Vehicle City Distribution), an advanced mobility project funded by the European Commission.[11] Solar recharging stations were envisioned, but were not built. The fleet trial ended in August 2001.

About sixty 1998-1999 Audi Duo PHEVs were built. However, few customers were prepared to pay twice the price as the base model A4 equipped with an identical diesel engine, and series production was stopped.



The Electric Power Research Institute (EPRI) sponsored the Hybrid Electric Vehicle Alliance to promote and develop original equipment manufacturer commercialization of plug-in hybrid electric vehicles. Alliance members include major automakers, national labs, utilities, and the University of California at Davis. EPRI's Hybrid Electric Vehicle Working Group published reports on PHEV attractiveness. Dr. Frank received new support from the European Commission, Southern California Air Quality Management District, Yolo-Solano Air Quality Management District, California Air Resources Board, and other governmental agencies.


The U.S. Department of Energy created the National Center of Hybrid Excellence at UC Davis, with Dr. Frank as Director. Dr. Frank also obtained substantial GM funds to hybridize and plug-in GM's EV1. EPRI's Hybrid Electric Vehicle Working Group (HEVWG) published a report on costs and efficiencies of hybrid and plug-in hybrid vehicles.[12] The report evaluated a small car, a midsize car, and an SUV, and simulated four powertrains for each vehicle: a conventional powertrain, a parallel HEV, a PHEV-20, and a PHEV-60.

Terminology note: A plug-in hybrid's all-electric range is designated by PHEV-(miles) or PHEV(kilometers)km representing the distance the vehicle can travel on battery power alone. For example, a PHEV-20 can travel 20 miles without using its internal combustion engine, or about 32 kilometers, so it may also be designated as PHEV32km.[13]

Entrepreneurs, environmentalists and engineers created the California Cars Initiative CalCars is a non-profit PHEV advocacy and technology development group.

The redesigned Renault Kangoo Elect'road operates in blended mode.

Renault began selling the Elect'Road, a plug-in series hybrid version of their popular Kangoo, in Europe. It was sold alongside Renault's "Electri'cite" electric-drive Kangoo battery electric van. The Elect'Road had a 150 km range using a nickel-cadmium battery pack and a 500 cc, 16 kW liquid-cooled gasoline "range-extender" engine. It powered two high voltage/high output/low volume alternators, each of which supplied up to 5.5 kW at 132V at 5000 rpm. The operating speed of the internal combustion engine (and therefore the output delivered by the generators) varied according to demand. The fuel tank had a capacity of 10 litres and was housed within the right rear wheel arch. The range extender function was activated by a switch on the dashboard. The on board 3.5 kW charger could charge a depleted battery pack to 95% SOC in about four hours from 220 volts. Passenger compartment heat was powered by the battery pack as well as an auxiliary coolant circuit that was heated by the range extender engine. Renault sold about 500, primarily in France, Norway and the UK, for about 25,000 euros each[14] and redesigned the Elect'road in 2007.

With support from the Southern California Air Quality Management District, the California Air Resources Board, the National Renewable Energy Laboratory, the Electric Power Research Institute, and Volkswagen, Alan Cocconi of AC Propulsion converted a Volkswagen Jetta into a plug-in series hybrid. The engine was replaced with a 120 kW electric motor and 8.7 kWh’s worth of lead-acid batteries, which were charged by a trunk-mounted 1.4-liter internal combustion engine from a Volkswagen Lupo.[15]

Professor Frank's vehicles were shown at the Paris International Auto Show and demonstrated to about 200 Renault engineers at its Paris headquarters. In the same year, Toyota shipped Coulomb, a University of California Davis Plug-in Hybrid Electric Vehicle, to Toyota City to demonstrate it to about 250 engineers and executives at two of Toyota's primary Tier 1 suppliers, Koyo Seiko, and Aisin AW (Aisin built the 1998-2003 Toyota Prius hybrid transaxle, as well as those used in the Ford Escape Hybrid, Toyota Camry Hybrid, and Nissan Altima Hybrid).

Lithium-ion battery pack, with cover removed, in the CalCars plug-in hybrid converted Toyota Prius

In September, the California Cars Initiative converted a 2004 Toyota Prius into a prototype of what it calls the PRIUS+. With the addition of 130 kg (300 lb) of lead-acid batteries, the PRIUS+ achieved roughly double the gasoline mileage of a standard Prius and can make trips of up to 15 km (9.3 mi) using only electric power.[16] The vehicle, which is owned by CalCars technical lead Ron Gremban, is used in daily driving, as well as a test bed for various improvements to the system.

Also in September, DaimlerChrysler displayed a plug-in hybrid version of its popular Mercedes-Benz Sprinter 311 CDI commercial van at the 2004 Internationale Automobil-Ausstellung Commercial Vehicle Show in Frankfurt, Germany.[17] The diesel-engine PHEV Sprinters had a maximum all electric range of 30 kilometers. Hand-built in Sindelfingen, Germany by Mercedes-Benz, the vehicles were tested around the clock, and some were placed in commercial fleet environments. The PHEV Sprinter's engine could be turned off by the driver for operation in historic European city centers that had outlawed internal-combustion engines.

By the end of the year, Dr. Frank's student teams had built and operated seven proof-of-concept and proof-of-demonstration prototype Plug-in Hybrid Electric Vehicles, including 6-passenger sedans (Taurus and Sable), Sport Utility Vehicles (Suburban, Explorer), two-seater sports car (GM EV1), and two ground-up 80 mpg sports cars, and the CalCars PRIUS+ prototype and EDrive Systems conversions were demonstrated.


Additional DaimlerChrysler Mercedes-Benz Sprinter 15-passenger van PHEV prototypes were completed.[18] EPRI, along with a number of utilities and government agencies, worked with DaimlerChrysler to deliver 4 Sprinter PHEV vans to test fleets.[19]

In August, four companies - Raser Technologies,[20] Maxwell Technologies, Electrovaya, and Pacific Gas and Electric - formed the Plug-In Hybrid Consortium[21][22] to help reduce the research and design gap between component suppliers and OEMs and to accelerate the development of critical PHEV components. Since then, nine other component companies and three more utility companies, as well as CalCars and Plug In America, have joined the consortium.


At the UC Davis Hybrid Center, teams led by Professor Andrew A. Frank[23] have been designing and building working prototypes, installed into a GM Equinox for the Challenge X competition.[24]

PHEV conversions of IVECO medium-duty diesel-powered commercial vehicles, sold as Hybrid Daily Bimodales, are offered by Micro-Vett SPA of Imola, Italy in truck, nine-passenger van, and 20-passenger school bus configurations.[25] Micro-Vett offers their conversions with either lead-acid or lithium-ion battery packs, which have an advertised all-electric range of 25 kilometers, or 45 to 100 kilometers, respectively.[26]

January 7: General Motors' Chevrolet Volt was unveiled[35] at Detroit's North American International Auto Show.[36] The Volt is part of GM's E-Flex architecture, which is expected to initially feature a plug-in capable, battery-dominant series hybrid architecture. Future E-Flex plug-in hybrid vehicles may use gasoline, diesel, or hydrogen fuel cell power to supplement the vehicle's battery. General Motors envisions an eventual progression of E-Flex vehicles from plug-in hybrids to pure electric vehicles, as battery technology improves.[37] General Motors presented the Volt as a PHEV-40 that starts its engine when 40% of the battery charge remains, and which can achieve a fuel economy of 50 mpg (4.7 l/100 km), even if the vehicle is not plugged in.[38]

Demonstration Toyota Prius Plug-in Hybrid produced for real-world testing.

On June 1, 2009, Volvo announced the launching of series production diesel-electric plug-in hybrids by 2012.[93][94][95] The company plans to sell a series hybrid with the goal of achieving emissions of less than 50 grams of CO2 per kilometer.[94][95] Two Volvo V70 demonstrators were converted to PHEVs and are undergoing a test trial in real world conditions since December 2009. This demonstration project is a joint venture with Vattenfall, a Swedish energy company. As reported by the test drivers, the V70 Plug-in Hybrid demonstrators have an all-electric range between 20 kilometres (12 mi) to 30 kilometres (19 mi) . The test plug-in hybrids were built with a button to allow test drivers to manually choose between electricity or diesel engine power at any time.[96][97]

On October 2010 Lotus Engineering unveiled the Lotus CityCar at the 2010 Paris Motor Show, a plug-in series hybrid concept car designed for flex-fuel operation on ethanol, or methanol as well as regular gasoline.[116][117] The lithium battery pack provides an all-electric range of 60 kilometres (37 mi), and the 1.2-liter flex-fuel engine kicks in to allow to extend the range to more than 500 kilometres (310 mi).[116][117]

Henrik Fisker showed the first production model of the Fisker Karma at the 2010 Paris Motor Show.[118]

General Motors began deliveries of the Chevrolet Volt in the United States in December 2010. The Volt has an all-electric range of 35 miles (56 km) according to the United States Environmental Protection Agency.[119] A total of 326 Volts were delivered to retails customers during 2012.[120]


Retail deliveries of the Fisker Karma began in November 2011.

Fisker Automotive initially scheduled sales of its Karma PHEV by the fourth quarter of 2009 in the U.S., and starting in 2010 in Europe.[121] After re-scheduling the Fisker Karma market launch to September 2010, and missing its target to build 70 to 100 test cars in 2010,[122] production began in July 2011.[123] The Valmet plant in Finland began production with five cars a week. By December 2011 the production rate was 25 units a day.[124] The first deliveries of the Fisker Karma, with an all-electric range of 32 miles (51 km), took place in the U.S. in July 2011.[125] Karma deliveries to retail customers began in November 2011.[126]

Chrysler began in 2011 field testing of the Dodge Ram 1500 Plug-in Hybrid in the United States with 140 units. The plug-in pickups were allocated to local and state governments, utility companies, and an U.S. Army base. This is demonstration program only, and Chrysler stated it has no plans for a production version. The Ram PHEV has an EV range of 20 mi (32 km).[127][128]

BYD Auto reported sales over 1,000 BYD F3DMs by October 2011.[129] Cumulative sales of the Chevrolet Volt in the U.S. and Canada reached 8,272 units through December 2011.[130][131]


Deliveries of the Opel Ampera in Europe began in February 2012.

The European version of the Volt, the Opel Ampera, was released to customers in Europe in February 2012. Opel reported that most of the Ampera clients are fleet or business customers.[132] Deliveries of the right-hand drive Vauxhall Ampera in the UK began in May 2012.[133] As of October 2012, more than 33,000 units of the Volt/Ampera family have been sold worldwide. The United States is the world's top selling market with 19,309 Volts sold during the first ten months of 2012, and cumulative sales of 27,306 units since December 2010.[120][130][134][135] The second best selling market is the Netherlands with 2,175 Amperas and 241 Volts sold through October 2012.[136][137] Canada ranks third with 1,075 Volts sold during 2012 and cumulative sales of 1,350 units between September 2011 and October 2012,[138] followed by Germany with 1,012 Amperas and 48 Volts registered through October 2012.[139][140]

Production version of the 2012 Toyota Prius Plug-in Hybrid.

The Toyota Prius Plug-in Hybrid was released in Japan in January 2012, followed by the United States in February 2012, and Europe in June 2012.[141][142][143] As of 31 October 2012, a total of 21,600 Prius PHVs have been sold worldwide, with 9,623 units sold in the United States through October 2012, followed by Japan with 9,500 units sold through October 2012, and 1,867 units sold in Europe through September 2012.[134][135][144][145]

In April 2012 BYD Auto announced that due to its low sales, the F3DM will be replaced by the BYD Qin (pronounced “Chin”) plug-in hybrid, which was unveiled at the 2012 Beijing International Automotive Exhibition.[146][147][148]

A two-year demonstration program with 25 Chrysler Town & Country E85 flexible-fuel plug-in minivans began in April 2012. The first units were delivered in Auburn Hills, Michigan and Charlotte, North Carolina.[149][150] The demonstration program was halted in September 2012, and Chrysler recalled the 23 units deployed at the time due to damage sustained by three separate Dodge Ram 1500 Plug-in Hybrids participating in a parallel program when their battery packs overheated. The carmaker plans to upgrade the battery packs shared by both vehicles with cells that use a different lithium-ion chemistry before the vehicles go back on service. No minivans were involved in any incidents.[151]

A Fisker Karma and an Opel Ampera charging in Utrecht, the Netherlands.

Fisker Automotive reported that around 1,500 units have been delivered in the U.S. and Europe by September 2012.[152] The Netherlands, with 138 units sold through October 2012,[136][137] is the top selling European market for the Karma.[153]

The Ford C-Max Energi was released in the U.S. in October 2012.

Sales of plug-in hybrid cars in the Netherlands during 2012 have been notable, as PHEV sales took the lead over all-electric cars during the first nine months of 2012. In addition to the Opel Ampera ranking as the best selling electric-drive car with 1,927 units sold during 2012, the Prius Plug-in Hybrid ranks second, with 610 units sold between June and September 2012, and the Chevrolet Volt ranks third with 205 units sold during the first months of the year. Adding 134 Fisker Karmas sold during 2012, the group of plug-in hybrid cars leads the Dutch market with 2,876 units sold during the first nine months of 2012, representing more than 80% of passenger EV sales in the country during this period.[154] As of September 2012, the Nissan Leaf was the top selling all-electric car in the country, with 163 units sold during the year, and a total of 457 units sold in the Netherlands since their introduction in mid-2011.[136][137]

Deliveries of the Ford C-Max Energi began in the U.S. by mid October 2012.[155] The C-Max Energi has an all-electric range of 21 mi (34 km) and an EPA rating for combined city/highway fuel economy in all-electric mode of 100 MPG-e (2.4 L/100 km). The Energi combined rating is 5 MPG-e better than the 2012 Toyota Prius Plug-in, and 2 MPG-e better than the 2013 Chevrolet Volt, allowing the C-Max Energi to become America’s most fuel-efficient plug-in hybrid in all-electric mode.[156][157] The Volvo V60 Plug-in Hybrid, the world's first diesel plug-in hybrid, was released in Sweden by late 2012.[158] Deliveries are scheduled to begin in the rest of Europe in early 2013.[159]


Deliveries of the Ford Fusion Energi began in the U.S. in March 2013.

Sales of the Honda Accord Plug-in Hybrid began in the U.S. in January 2013, and availability is limited to California and New York.[160] The Mitsubishi Outlander P-HEV was released in the Japanese market also in January 2013, becoming the first SUV plug-in hybrid in the market.[161] The Ford Fusion Energi was released in the U.S. market by late February 2013, and retail deliveries began in March 2013.[162][163] Production of the BYD F3DM was ended, as its successor, the BYD Qin, is scheduled to start deliveries in June 2013.[164][165]

Future vehicles

Other plug-in hybrid vehicles slated to the market between 2013 and 2014 are the BYD Qin, Porsche 918 Spyder, McLaren P1 (limited edition), Cadillac ELR, Porsche Panamera S E-Hybrid, and the BMW i8.
