An electric car or electric vehicle is a passenger automobile that is propelled by an electric traction motor, using electrical energy as the primary source of propulsion. The term normally refers to a plug-in electric vehicle, typically a battery electric vehicle, which only uses energy stored in on-board battery packs, but broadly may also include plug-in hybrid electric vehicle, range-extended electric vehicle and fuel cell electric vehicle, which can convert electric power from other fuels via a generator or a fuel cell.
