Classification of new energy vehicles?

Hello, new energy vehicles mainly include fuel cell electric vehicles (FCEV), hybrid vehicles, hydrogen-powered vehicles, pure electric vehicles (BEV, including solar vehicles) and other new energy vehicles (such as high-efficiency energy storage devices, dimethyl ether, etc.). The new energy vehicle refers to an automobile that uses unconventional vehicle fuel as the power source (or conventional vehicle fuel and new vehicle power device), integrates the advanced technology of vehicle power control and driving, and has advanced technical principles, new technologies and new structures. Advocating new energy vehicles is to meet the needs of environmental protection and oil crisis, and to reduce or give up the current mainstream models that burn traditional gasoline or diesel-driven internal combustion engines.
