An electric vehicle battery (EVB) or traction battery is a battery used to power the propulsion of a battery electric vehicles (BEVs).Vehicle batteries are usually a secondary (rechargeable) battery.Traction batteries are used in forklifts, electric Golf carts, riding floor scrubbers, electric motorcycles, full-size electric cars, trucks, and vans, and other electric vehicles.atteries for electric vehicles are characterized by their relatively high power-to-weight ratio, energy to weight ratio and energy density; smaller, lighter batteries reduce the weight of the vehicle and improve its performance.
