New energy vehicles battery side panels

The battery is the core component of the new energy vehicle. The power battery case and the battery side plate have a certain protective effect on the internal battery. The traditional new energy vehicles battery side panels are made of steel material. However, with the development of environmental protection and lightweight of new energy vehicles, aluminum alloy materials have gradually been promoted in battery shells due to their unique advantages.

5083 aluminum plate for side plate of new energy vehicles battery

The material used for the side plate of the early aluminum alloy battery shell is mainly 3003 aluminum alloy 0-state material. However, the tensile strength of 3003-o material is about 115mpa, and the yield strength is about 60mpa, which is quite different from the strength of conventional steel materials. After continuous research, the current power battery module side plate is generally made of 5083 aluminum plate, which has medium strength, easy molding, high temperature corrosion resistance, and good heat transfer.

What is the role of the new energy vehicles battery side panels?

The isolation plate is not a solid baffle in the full sense. It has small holes in itself, and the two-level compound is too large to penetrate. However, the lithium ions separated by the compound during charging and discharging are small enough to pass through, and then undergo oxidation and reduction reactions with the two-stage compound to supply electricity.
