The production process of vehicle battery case mainly includes the following aspects:

1. Material selection: The materials of new energy battery shells generally use materials with high strength, high toughness, corrosion resistance, high temperature resistance and other characteristics, such as aluminum alloy, magnesium alloy, titanium alloy, etc. When selecting materials, factors such as the cost of materials, processing performance, and corrosion resistance need to be considered.

2. Shell design: The design of the new energy battery shell needs to consider the size, shape, capacity and other factors of the battery, and also needs to consider the characteristics of the battery such as heat dissipation, waterproof, and dustproof. During the design process, software such as CAD is required for simulation and optimization to ensure the quality and performance of the housing.

3. Processing technology: The processing technology of new energy vehicle battery shell includes casting, forging, stretching, deep drawing stamping and other methods. Different processing methods are suitable for different materials and housing shapes. During processing, it is necessary to pay attention to factors such as dimensional accuracy, surface finish, and uniformity of wall thickness of the shell.

4. vehicle battery case surface treatment

The surface treatment of new energy battery shells includes anodizing, electroplating, spraying and other methods. The purpose of surface treatment is to improve the corrosion resistance, aesthetics and electrical properties of the shell. In the process of surface treatment, it is necessary to pay attention to the concentration, temperature, time and other factors of the treatment solution.

5.vehicle battery case testing and quality control:

Multiple tests and quality control are required during the production process of new energy vehicle battery shells to ensure the quality and performance of the shell. Inspection items include dimensional accuracy, wall thickness uniformity, surface finish, corrosion resistance, etc. Quality control includes the selection of raw materials, the control of processing technology, the quality control of surface treatment, etc.

The production process of new energy vehicle battery cases is a complex process that requires the synergy of multiple links. Only through scientific design, fine processing, strict testing and quality control, can we produce high-quality, high-performance new energy battery shells and contribute to the development of the new energy vehicle industry.
