Venting Unit
High-performance high-voltage batteries are at the heart of electric mobility. To protect them, water and dust must be prevented from entering the battery system, but pressure equalization must be allowed. In case of a sudden pressure increase (e.g. caused by a thermal runaway), the Venting Unit must also reduce this pressure by opening in a controlled manner. Various technologies are available for this, such as a bursting membrane or reclosable valves. Each solution has its own advantages.
Product benefits
- Protects the high-voltage battery system under all operating conditions
- Permanent pressure equalization due to temperature or altitude differences
- Emergency venting at a defined overpressure in the battery system
- Water and dust tight to protect the battery system in case of larger water accumulations and high-pressure cleaning
