The internal volume of car battery and battery box is large,they are very sensitive to temperature change、pressure build-up or vacuum attraction,these will exert pressure to sealing device then make pollutant enter shell.they will further reduce battery life and reduce its performance;even lead to an explosion.For automotive battery pack,battery box and other non vacuum sealed components,PUW developed special components that can release pressure quickly,anti overflow,explosion proof,be waterproof and dustproof.In the normal work,they can be breathable quickly,when airs reach blasting value,passed to outside directly instantly,a large number of gas discharge,release equipment seal components internal strong pressures to avoid explosion or reduce explosion risk.
