New energy vehicle refers to the use of unconventional vehicle fuel as the power source (or the use of conventional vehicle fuel, the use of new vehicle power plant), the integration of vehicle power control and driving advanced technology, the formation of advanced technical principles, with new technology, new structure of the vehicle. New energy vehicles include pure electric vehicles, programmed electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles and so on.

The scope of new energy resources vehicle is changing constantly. At present, new energy vehicles are mainly powered by electric energy. According to the network information and related courses, the new energy resources vehicles can be divided into three categories: pure electric vehicle (BEV, EV), plug-in hybrid electric vehicles (HEV, FCEV). The battery electric vehicle is a kind of vehicle which uses the battery as the energy storage unit and the electric motor as the drive system. Plug-in Hybrid Electric Vehicle (PHEV) is a hybrid electric vehicle based on hybrid electric vehicle (HEV), which uses high-power electric motor and large-capacity battery and auxiliary external charging interface. Fuel Cell Electric Vehicle (FCEV) is a vehicle that uses hydrogen and oxygen to generate electricity as a power source under the action of a catalyst.
