The importance of the battery case in EV is that it not only needs to provide a sturdy structure to protect the expensive and sensitive battery cells, but also must ensure thermal management of the battery, prevent overheating, and protect passengers and batteries from damage in unexpected situations such as collisions. The design and material selection of the battery case directly affect the performance and safety standards of electric vehicles.
The battery case material is usually selected as Aluminum 3003 sheet, which can improve the conductivity of the power battery and contribute to the lightweight of the vehicle battery.
What is Aluminum 3003 Sheet
Aluminum 3003 Sheet is a manganese-alloyed material (1.2% Mn)It has good formability, good corrosion resistance and weldability. It is often used to make power battery shells in lightweight automobiles, cookware, food storage devices, tanks and silos on transportation equipment, metal sheet pressure vessels and pipe.
