Electric Vehicles (EVs) A vehicle with one or more electric motors powered by an independent source of electricity (batteries, fuel cells, capacitors, etc.) and not by an internal combustion engine. Electric vehicles run entirely on battery power and produce zero exhaust emissions. They are charged from the mains.
