Battery electric vehicle and Electric car
Battery electric vehicles (BEVs), also known as all-electric vehicles (AEVs), are electric vehicles whose main energy storage is in the chemical energy of batteries. BEVs are the most common form of what is defined by the California Air Resources Board (CARB) as zero emission vehicle (ZEV) because they produce no tailpipe emissions at the point of operation. The electrical energy carried on board a BEV to power the motors is obtained from a variety of battery chemistries arranged into battery packs. For additional range genset trailers or pusher trailers are sometimes used, forming a type of hybrid vehicle. Batteries used in electric vehicles include "flooded" lead-acid, absorbed glass mat, NiCd, nickel metal hydride, Li-ion, Li-poly and zinc-air batteries.
Attempts at building viable, modern battery-powered electric vehicles began in the 1950s with the introduction of the first modern (transistor controlled) electric car - the Henney Kilowatt, even though the concept was out in the market since 1890. Despite the poor sales of the early battery-powered vehicles, development of various battery-powered vehicles continued through the mids 1990s, with such models as the General Motors EV1 and the Toyota RAV4 EV.
Battery powered cars had primarily used lead-acid batteries and NiMH batteries. Lead-acid batteries' recharge capacity is considerably reduced if they're discharged beyond 75% on a regular basis, making them a less-than-ideal solution. NiMH batteries are a better choice, but are considerably more expensive than lead-acid. Lithium-ion battery powered vehicles such as the Venturi Fetish and the Tesla Roadster have recently demonstrated excellent performance and range, but they remain expensive, nevertheless is used in most mass production models launched since December 2010.
As of December 2013, several neighborhood electric vehicles, city electric cars and series production highway-capable electric cars and utility vans are available in several countries, including Tesla Roadster, GEM cars, Buddy, Mitsubishi i MiEV and its rebadged versions Peugeot iOn and Citroën C-Zero, Chery QQ3 EV, JAC J3 EV, Nissan Leaf, Smart ED, Mia electric, BYD e6, Renault Kangoo Z.E., Bolloré Bluecar, Renault Fluence Z.E., Ford Focus Electric, BMW ActiveE, Renault Twizy, Tesla Model S, Honda Fit EV, RAV4 EV second generation, Renault Zoe, Mitsubishi Minicab MiEV, Roewe E50, Chevrolet Spark EV, Fiat 500e, BMW i3 and Volkswagen e-Up!. Other models scheduled for market launch between 2013 and 2014 include the Volkswagen e-Golf, Mercedes-Benz B-Class Electric Drive,Volkswagen XL1, and Tesla Model X.[39] As of January 2014, the world's best selling highway-capable plug-in electric car is the Nissan Leaf all-electric car, with over 100,000 units sold since December 201
