Electric cars run at least partially on electricity.
Unlike conventional vehicles that use a gasoline or diesel-powered engine, electric cars and trucks use an electric motor powered by electricity from batteries or a fuel cell.
Not all electric vehicles (or “EVs”) work the same way. "Plug-in hybrids" offer both a gasoline or diesel engine and an electric motor: the motor is powered by a battery that can be recharged by plugging in.
Other EVs forgo liquid fuels entirely, operating exclusively on electricity ("battery electric" vehicles).
Still others power an electric motor by converting hydrogen gas into electricity ("hydrogen fuel cell" vehicles).
Conventional hybrid vehicles also have an electric motor, but aren’t considered EVs as they can’t be plugged-in.
