Power Battery Component Machining

Customer Requirements: A leading power battery manufacturer was looking for a reliable machining partner to produce high-precision aluminum alloy housings and copper busbars for their latest generation of lithium-ion batteries. The aluminum housings needed to have extremely tight tolerances, with wall thickness variations within ±0.05mm, to ensure proper sealing and protection of the battery cells. The copper busbars required precise cutting and shaping to minimize electrical resistance and fit perfectly within the battery module assembly. Moreover, the surfaces of both components had to be free from any burrs or scratches that could potentially cause short circuits or affect the battery's performance.
Solutions and Machining Processes:
- CNC Milling for Aluminum Housings: The enterprise employed advanced CNC milling machines with high-speed spindles and automatic tool changers. The machines were programmed to mill the aluminum alloy blocks into the complex shapes of the battery housings. To achieve the tight wall thickness tolerances, real-time monitoring and feedback systems were used to adjust the cutting parameters during the machining process. After the milling operation, a chemical etching process was carried out to remove any remaining burrs and improve the surface finish, followed by an anodizing treatment to enhance the corrosion resistance of the housings.
- CNC Punching and Bending for Copper Busbars: For the copper busbars, a combination of CNC punching and bending machines was utilized. The punching machine precisely cut the copper sheets into the required shapes and sizes, while the bending machine accurately formed the busbars according to the specific design angles. To minimize electrical resistance, the edges of the busbars were carefully polished to a smooth finish. Additionally, a plating process was applied to the copper surfaces to further improve their conductivity and oxidation resistance.
Results and Customer Feedback: The machined aluminum housings and copper busbars met all the quality and performance requirements of the power battery manufacturer. The batteries assembled with these components exhibited excellent safety and efficiency characteristics during extensive testing and real-world applications. The customer was extremely satisfied with the precision and reliability of the machining services provided. They established a long-term strategic cooperation with the enterprise, planning to jointly develop more advanced battery components and manufacturing technologies in the future.
