Safety PBE (VSD)
The Pressure Balance Element for Li-ion batteries
The passive Pressure Balance and Safety Element (short: Safety PBE) combines two independent functions in one compact component: In use function, it provides ventilation and the necessary pressure equalization between the inside and outside of the battery housing while maintaining a high protection class. This prevents the formation of condensation in the interior and extends the service life of the overall system. If an unexpected explosion of one or more Li-ion cells inside the battery housing occurs (thermal runaway), the second function comes into effect: The safety DAE clears the way for the hot gases to the outside.
