With the attention and support of the government, it has developed rapidly. The battery pack of new energy vehicles is the core of the whole car, and the battery pack shell is the main carrier of the battery pack system of new energy vehicles. Protective effects. In addition, the main structural components of the new energy power battery shell operation battery pack system, after carrying the entire battery pack system, are installed and cooperated with the body to meet the requirements for providing electric energy for new energy vehicles.

Automobile is an indispensable transportation work in people's daily life. With the popularization of automobiles, it also increases environmental pollution. In recent years, electric vehicles have the advantages of diversifying energy sources due to their low pollution to the atmospheric environment. New energy vehicles are characterized by saving fuel, reducing exhaust emissions, high efficiency, and low noise.

As the carrier of the battery module, the new energy power battery plays a key role in the safety protection of the battery module. The manufacturing method of the new energy vehicle battery pack shell is as follows:
One: Use the die-casting machine to die-cast the high-ductility die-casting aluminum alloy to form a shell. During the die-casting process, control the die-casting process parameters, mold temperature, liquid aluminum alloy temperature, liquid aluminum alloy injection volume and cavity vacuum degree .
Two: Trim and deburr the shell of the new energy power battery pack, and perform heat treatment.
Three: Through precision fixtures and high-performance CNC machines, CNC machining is performed on the new energy power battery casing to form mounting surfaces, connector parts, and bolt holes/threaded holes.
Four: Through the on-line monitor, on-line monitoring of the installation surface, connector parts, bolt holes/thread holes of the new energy power battery shell during processing and three-coordinate inspection after processing.
Five: Chromizing the surface of the new energy power battery pack shell to form the battery pack shell.
