Under the joint efforts of governments and enterprises, the new energy automobile industry in China shows a good development trend in recent years.

The new energy automobile refers to all other energy automobiles except gasoline and diesel engines, including fuel cell automobiles, oil-electricity hybrid automobiles, hydrogen energy power automobiles, solar automobiles and the like.

At present, compared with hydrogen energy and solar energy, the technical obstacle of gradually replacing fuel oil by adopting electric energy is small, but the development of battery technology is limited, and the use of the current pure electric vehicle has certain limitation. The fuel consumption of the truck is larger than that of a passenger vehicle, so that the design of the fuel-electric hybrid truck is of great significance for reducing the fuel consumption of the truck. For passenger vehicles, the traveling distance of a truck is usually long, the utilization rate is high, the charging speed is limited (the service life of a battery can be shortened by a quick charging technology), and the currently designed hybrid oil-electricity truck with the battery pack capable of being replaced quickly is high in feasibility.
