Battery electric vehicles (BEVs) use electrical energy stored in a battery to power their propulsion system. These vehicles are designed to operate without the need for fossil fuels such as gasoline or diesel, which is why they are also called zero-emission vehicles, as they emit no harmful exhaust gases during use. The vehicle’s onboard battery is recharged by connecting it to an external power source, such as a domestic power outlet or a public or mobile charging station. Some BEVs can also regenerate energy during braking through a process called kinetic energy recovery.
The batteries used in battery electric vehicles may vary in terms of technology and capacity. Still, they are subject to continuous improvement aimed at increasing capacity, reducing time and improving charging modes to make BEVs increasingly convenient and practical for everyday use.
