Power management company Eaton’s eMobility business has introduced a single-stage vent valve for EV batteries. The valve acts as an over-pressure relief for the vehicle’s pack.

The valve’s resealing technology allows customers to specify very low opening pressures and testing for 100% functionality compared with the conventional burst-valve technology commonly used in the market at the moment.

Eaton says the valve features an easily assembled quick-connect technology, reducing complexity for battery pack manufacturers while ensuring a robust connection that stays in place.

It plans to add new technologies to its battery safety products, including a dual-stage valve that incorporates all the features of the single-stage version as well as humidity management solutions for the inside of EV battery packs.
