Ⅰ、 Explosion-proof valve

　　1.Overview

 

A properly designed venting system provides protection from contaminants and maintains pressure equalization under normal operating conditions, helping to achieve longer-lasting housing and battery life cycles. In the rare event of thermal runaway, the vent must also be able to relieve pressure immediately, helping to avoid component failure or damage to other units.

To meet this challenge, we have developed the SST-Porous® pressure relief valve. The PTFE pressure relief membrane in the component is able to compensate for the pressure difference, and at the same time can prevent water, dust, dirt and even engine oil from entering. They made the development of the degasser only to protect the high voltage battery from heavy rain or temporary immersion, but this can even stop water pressure cleaners sprayed by the high voltage battery.
