BEVs


A battery electric vehicle, or BEV, is a type of electric vehicle (EV) that uses chemical energy stored in rechargeable battery packs. As with other electric vehicles, BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion. Sometimes, all-electric vehicles are refered as BEVs (although a plug-in hybrid is also a battery electric vehicle).Vehicles using both electric motors and internal combustion engines are examples of hybrid electric vehicles, and are not considered pure (or all) EVs because they operate in a charge-sustaining mode. * Regular hybrid electric vehicles cannot be externally charged. * 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 are BEVs during their charge-depleting mode. All-electric and plug-in hybrids are off-vehicle charge capable (“OVCC” or pluginable), which means their batteries can be charged from an off-vehicle electric energy source that cannot be connected or coupled to the vehicle while the vehicle is being driven. (so, it is autonomous).
