Integrated power battery cover plate
At present, the domestic products of dynamic cover plate and explosion-proof strip are mainly composed of aluminum for explosion-proof strip annealed after thinning and deep drawing, then welded with cover plate by laser, and directly pressed for aluminum plate without annealing. Without welding, the thickness of the explosion-proof piece is uniform and the performance is stable, which reduces the welding process of the explosion-proof piece and the cover plate and the hidden dangers of leakage and blasting pressure caused by the welding, and represents the development direction of the power battery shell cover in the future.
