An electric vehicle (EV) is a vehicle that is propelled by one or more electric motors. It can be powered by a collection system, extravehicular sources of electricity, or by a battery on its own (sometimes charged by solar panels, or by converting fuel to electricity using fuel cells or a generator). After a decade of strong development, the global electric car stock reached 10 million in 2020, a 43% increase over 2019 and a 1% stock share. In 2020, battery electric vehicles (BEVs) represented two-thirds of new electric car registrations and two-thirds of the stock. China had the largest fleet, with 4.5 million electric vehicles, while Europe had the highest yearly rise, reaching 3.2 million in 2020. In 2020, around 3 million new electric vehicles were registered. Europe led the way for the first time, with 1.4 million new registrations. China came in second with 1.2 million registrations, while the United States recorded 295 000 new electric vehicles.
