As we all know, as a new technology field, new energy vehicles effectively and ease the pollution problem of traditional fuel cars, and alleviate the dilemma of increasingly scarce petroleum resources. The implementation of new energy vehicles is imperative. At present, the heat of new energy vehicles has not been reduced, which is a major trend in the future development of automobiles.

In order to increase the mileage, new energy electric vehicles need a large number of lithium battery modules, each module is composed of several battery boxes, so that the quality of each battery box has a great impact on the quality of the entire battery module. . Therefore, the use of aluminum alloy as a material to make the battery casing becomes an inevitable choice for the power battery package.

The aluminum alloy power battery case has a small density, increases the volume of the lithium battery, and has better safety performance and stability. The aluminum alloy battery case adopts 3003 aluminum plate, 3003 aluminum plate is easy to weld, and the aluminum alloy battery case made of 3003 aluminum plate has excellent sealing performance and compression resistance, and can be better protected as a package. Electrode material and prevent leakage of electrolyte.

High-quality 3003 aluminum plate is not only used for battery casing, 3003 aluminum plate has good formability, very good corrosion resistance and weldability, and is often used in the manufacture of power battery casings, cookware, food storage devices, transportation equipment in lightweight automobiles. Tanks, silos, sheet metal pressure vessels and pipes. 3003 aluminum alloy plate is used for stamping parts, models, tanks, shells, etc. It has many advantages such as good surface, good plasticity and pressure resistance.
