Electric car

An electric car is a vehicle that makes use of by chemical energy stored in rechargeable battery packs, and electric motors and motor controllers instead of an internal combustion engine (ICE).

Vehicles using both electric motors and Ices (hybrid electric vehicles) are examples of hybrid vehicles, and are not deliberate pure electric vehicles (EVs) because they operate in a charge-sustaining mode. Hybrid vehicles with batteries that can be charged externally to displace some or all of their ICE power and gasoline fuel are called plug-in hybrid electric vehicles (PHEV), and are pure battery electric vehicles (BEVs) during their charge-depleting mode. Electric vehicles include automobiles, light trucks, and neighborhood electric vehicles.

Electric cars were among the earliest automobiles. They produce no exhaust fumes, and minimal pollution if charged from most forms of renewable energy. Many are capable of stepping up exceeding that of conventional vehicles, are quiet, and do not produce noxious fumes. Electric cars reduce dependence on petroleum and decrease or eliminate greenhouse gas emissions, depending on how their electricity is produced.
