New energy vehicles in a broad sense, also known as alternative fuel vehicles, include pure electric vehicles, fuel cell electric vehicles and other vehicles that all use non-petroleum fuels, as well as hybrid vehicles, ethanol gasoline vehicles and other vehicles that use some non-petroleum fuels.
All existing new energy vehicles are included in this concept and can be divided into six categories: hybrid vehicles, pure electric vehicles, fuel cell vehicles, alcohol ether fuel vehicles, natural gas vehicles and so on.
