Important structure of lithium ion battery explosion-proof test box

Lithium-ion battery explosion-proof test box is mainly used for the development of new lithium-ion battery products or daily inspection of lithium-ion battery performance. The battery is overcharged and over-discharged. During charge and discharge tests, the battery is placed in an explosion-proof box and an external charge-discharge tester is connected. To protect the operator and the instrument. When designing a lithium-ion battery explosion-proof box, the explosion-proof door is not only used as the entrance and exit of the test battery, to observe the condition during performance testing, but the more important function is to act as a leakage surface when the lithium ion battery explodes, releasing the impulse wave of the explosion of the lithium ion battery. The explosion-proof box wall of lithium-ion battery must have the ability to resist explosion shock wave, and can limit the destructive use of explosion within a certain range. Lithium-ion battery explosion-proof test box box structure adopts double-layer design: internal SUS material plus Teflon tape + outer box cold-rolled plate baking paint treatment; SUS has better high temperature resistance than iron plate, and the inside of the test box is attached Teflon tape can effectively prevent corrosion, insulation, flame retardant and easy to clean. Therefore, the box structure should be scientifically designed. For example, the explosion-proof design of lithium-ion batteries is the same as the full-plate metal structure of automobiles, and the overall results of the automobile crash test are considered. The air tightness of the lithium-ion battery box should be tested during the production process to judge the waterproof and dustproof ability of the lithium-ion battery box. During the test, the inside of the box should be inflated and the internal pressure of the box should be tested to reach the test box. The purpose of the airtightness of the body, but an explosion-proof valve device is installed on one side of the lithium-ion battery box. There are many pores on the explosion-proof valve device, and the pores can circulate with the outside air. Therefore, the airtightness of the box is tested When the explosion-proof valve is effectively sealed to ensure the accuracy of the test. The important structure of the lithium-ion battery explosion-proof test box Lithium-ion battery is mainly used as the explosion-proof device of the lithium-ion battery by scoring and welding the explosion-proof film. When the battery heats up, the gas inside the battery expands and the pressure increases to a certain extent, the mark or the explosion-proof film will come off. Welding, rupture, venting and pressure relief, so as to prevent the battery from exploding. It is difficult to achieve sufficient consistency in the structure of lithium-ion battery explosion-proof devices, and the start-up pressure value of such explosion-proof devices is large, so that when the battery is abnormal, it cannot be immediately vented and pressured, resulting in lithium-ion batteries explosion occurs. When designing the explosion-proof box, the explosion-proof box door is not only used as the entrance and exit of the test battery to observe the condition during the performance test, but the more important function is to act as a leakage surface when the lithium ion battery explodes, releasing the shock wave from the explosion of the lithium ion battery. The lithium ion battery explosion-proof test box is composed of an inner box, an outer box, a pressure relief system and an electrical control system. Lithium-ion battery explosion-proof test box box structure adopts double-layer design: internal SUS material plus Teflon tape + outer box cold-rolled plate baking paint treatment; SUS has better high temperature resistance than iron plate, and Teflon is added to the inside of the test box. Long tape can effectively prevent corrosion, insulation, flame retardant and easy to clean. Therefore, the cabinet structure should be scientifically designed, as is the lithium-ion battery laboratory, which has a certain temperature and impact resistance, and is the key to reusability. The outer box cold-rolled sheet baking varnish treatment can prevent rust and achieve a generous and beautiful effect.
