Car protection breathable
Explosion-proof Vent Solution
Solution
■Protective solution provided by Voir
Specification on Voirs Protective Vent To protect the sealed but not vacuum components, like automobile’s battery pack/ box, Voir has developed EPV protective vents that not only help to rapidly release the pressure but also resist explosion/ water/ dust/ oil. Normally, it helps the enclosure to breath; but when the pressure reaches the critical point,it breaks the membrane to release a large number of air, by this way it releases the great pressure of the inside and prevents explosion from happening or lower the damage from explosion.
■Reliability Requirement：
>>Service life being more than 10 years
>>Protective rate can still be IP67 after service life span test
■ The Performance of the Protective Vent(When the Inner Pressure of the Automobile Battery Reached 80Kpa, Alarm will get to work immediately to prevent explosion)

Peculiarity
>> Balancing pressure (pressure from inner and outer battery)
>> Releasing pressure (it can rapidly vent the gas after the cell abnormally exhausts, preventing damage to the battery or other components from excessive pressure)
>>Battery can be tested the air tightness by installing onto holder
Installation
Advantage
>>Extend the Normal Working Time
>>Lower Cost For Maintenance
>>Small Space Needed for the Vent
>>Better Structure
>>Technology Upgrade
