New Energy Vehicle Battery Module End Plate Aluminum Profile

New energy vehicle batteries are equipped with an end plate at both ends; the car battery is equipped with a panel on both sides; two panels and two end plates are fixed to each other, and the two end plates are used to install parts of the car battery and the supporting institutions connected to each other in order to fix the battery. With the rapid growth of new energy vehicles and lightweight automotive requirements for new energy vehicle battery end plates, the use of aluminum end plates, through the development and design of the battery end plate, can effectively optimize the structure while speeding up the product development cycle and can be used for the development and design of the battery end plate. Through the development and design of the battery end plate, the structure can be effectively optimized and the product development cycle can be accelerated at the same time.

　　Advantages of using aluminum profile for new energy vehicle battery end plates

(1) Long service life. Aluminum alloy shell after simulated aging test shows that its service life is more than 20 years, far more than metal and other traditional materials.

(2) Flame retardant, smoke-free, and non-toxic. Aluminum alloy material flame retardant grade up to FV0, in the high temperature burning under the smoke level of 15, smoke is non-toxic, toxicity level of ZA1 (quasi-safety level).

(3) Explosion-proof performance. The aluminum shell cover of the power battery is specially equipped with an explosion-proof device; in case of excessive pressure inside the battery cell, the explosion-proof device will automatically open to relieve pressure to prevent an explosion.

(4) Anti-aging performance. Among metal materials, aluminum has excellent anti-aging properties. The anti-aging performance test shows that in the use of different locations and different climate zones, the maximum surface aging thickness of 20 years is less than 50 μm. Most of the minimum thickness of the box is 5 mm, which is less than 1% of the thickness of the box, so there is no significant impact on the mechanical properties of the box.

(5) Lightweight. The size of the battery box’s mass has a great impact on the quality of the entire battery module. Because the aluminum alloy is denser than traditional stainless steel, using 3003 aluminum alloy to make the battery shell is an inevitable choice to reduce weight.
