What is the explosion-proof effect of the battery explosion-proof valve

Everyone knows that there are certain safety hazards when using batteries. Now there is a battery explosion-proof valve product on the market that can solve this worrying problem. With the increasing application of battery explosion-proof valves, many manufacturers have also attached importance to them. Many electric vehicles and electric vehicle batteries have applied battery explosion-proof valves. To know its effectiveness, we need to first take a look at its working principle.

For example, in PUW explosion-proof valves, the imported expanded polytetrafluoroethylene (E-PTFE) microporous membrane is selected as the main waterproof and breathable material. Moreover, the surface energy of this membrane is very low. Under the action of surface tension, small water droplets will quickly form large water balls on the surface of the E-PTFE membrane, allowing gas to pass through smoothly. Therefore, it has good waterproof and breathable performance.

Battery explosion-proof valve

The battery explosion-proof valve plays a certain role in explosion prevention. It can test whether its working state is normal. If the pressure inside the battery pack box is less than the explosion value set by the explosion-proof valve, then this state is normal.

If the pressure inside the chamber is too high or equal to the explosion-proof value set by the explosion-proof valve, the internal pressure will push open the built-in piston body. When the gas passes through the unobstructed channel to the outside, the gas is urgently discharged, and the pressure inside the chamber is rapidly reduced. This state plays an explosion-proof role.

Therefore, the battery explosion-proof valve plays a certain role during use. Moreover, more and more products are equipped with battery explosion-proof valves, greatly reducing the safety hazards of battery explosions.
