Introduction
This is a pressure relief valve, used in an EV lithium-ion battery pack for emergency venting. During normal operation, it prevents water and foreign material from entering the battery, protecting the battery modules from short-circuit. In a thermal runaway emergency, it opens reliably to vent gas, release pressure, and prevent damage to the battery while keeping passengers safe.
Features
- Prevents the spread of fire in the battery pack by releasing internal pressure, then re-sealing immediately.
- Valve opening pressure can be set to customer requirements.
- Waterproof breathable membrane (breather filter) can be added.
- Various assembly methods available based on requirements.
