[0002] Battery cars are also called "electric cars". They are pure electric vehicles powered by batteries (batteries) and driven by electric motors (DC, AC, series-excited, externally-excited). In recent years, they have been widely used in my country. Domestic battery cars are mainly used for sightseeing, security patrols, and cargo transportation. The main purpose of electric sightseeing cars is to carry passengers in parks, scenic spots, leisure resorts, universities, hospitals, golf courses, real estate companies, etc. The main purpose of electric patrol cars is to patrol security in stations and crowded places.
