tmax
The tmax pressure compensation and pressure overload valve (PCO valve) provides increased fire protection in case of thermal runaway (i.e. fire) inside lithium-ion battery housings.
- Releases flue gases into the environment in a controlled process once a defined overpressure has been reached to help prevent spread if fire occurs
- Structure is fireproof
- Ensures a very low tolerance of the individually designed burst pressure (starting at 250 mbar)
- Features a compact design and complies with the protection class IP67 and IP6K9K
- Parameters of the airflow and burst pressure can be easily scaled by adjusting the geometry
- Metallic design ensures optimal EMC shielding and enables an optional connection for routed smoke degassing via a connected duct system
- Use of a semi-permeable membrane compensates for the natural heat expansion during the charging and discharging of the battery and the air pressure fluctuations in the environments
- Rupture disk is used for the pressure overload function (burst function)
