Battery electric vehicle

The electric car, EV, or simply electric vehicle is battery electric vehicles (BEV) that utilize chemical energy stored in rechargeable battery packs. Electric vehicles use electric motors and motor controllers in its place of internal combustion engines (Ices). Vehicles using both electric motors and Ices are examples of hybrid vehicles, and are not measured pure BEVs because they operate in a charge-sustaining mode. Hybrid vehicles with batteries that can be exciting externally to displace some or all of their ICE power and gasoline fuel are called plug-in hybrid electric vehicles (PHEV), and are pure BEVs during their charge-depleting mode. BEVs are frequently automobiles, light trucks, neighborhood electric vehicles, motorcycles, motorized bicycles, electric scooters, golf carts, milk floats, forklifts and similar vehicles.

BEVs were among the earliest automobiles, and are more energy-efficient than interior combustion, fuel cell, and most other types of vehicles. BEVs create no tire fumes, and minimal pollution if charged from most forms of renewable energy. Many are capable of acceleration more than that of conventional vehicles, are quiet, and do not produce noxious fumes. It has been optional that, because BEVs reduce dependence on petroleum, they enhance national safety, and mitigate global warming by alleviating the greenhouse effect.
