The course mainly introduces the classification of new energy vehicles, the structure and working principle of pure electric vehicles, and the structural understanding of hydrogen fuel cell vehicles. New energy vehicles are divided into pure electric vehicle structure and working principle, hybrid electric vehicles, hydrogen fuel cell vehicles. New energy vehicle-related terms mainly explain the professional terms of common vehicles and parts of new energy vehicles, such as EV is a pure electric vehicle. Typical new energy vehicle structure mainly explains the structure and working principle of pure electric vehicles and hydrogen fuel cell vehicles. Pure electric vehicles mainly explain the structure of Changan Deep Blue model, hydrogen fuel cell vehicles mainly explain the fuel cell structure and working principle, as well as several common fuel cell vehicle structure working principle.
