Eaton introduces portfolio of battery pack vent valves for electrified autos


Energy administration firm Eaton’s eMobility enterprise has launched a single-stage vent valve for electrified car (EV) batteries. The valve acts as an overpressure reduction for the car’s battery pack.

Because the electrified car market continues to develop, battery packs have gotten progressively extra highly effective and create extra warmth. OEMs are designing new security programs to ease the impression of thermal occasions. Our new battery vent valve is designed to allow speedy overpressure launch within the battery pack.Jens Buhlinger, supervisor, Battery Expertise Improvement, Eaton’s Automobile Group

A battery pack thermal runaway state of affairs can happen when particular person cells contained in the unit fail attributable to bodily impression or brief circuit. Eaton’s single-stage battery vent valve might be exactly and flexibly designed to fulfill particular opening pressures and optimize venting.

The valve’s confirmed resealing know-how permits Eaton’s prospects to specify very low opening pressures and testing for 100% performance in contrast with the standard burst-valve know-how generally used available in the market at this time.

Our new battery vent valve options an simply assembled quick-connect know-how, lowering complexity for battery pack producers whereas guaranteeing a strong connection that stays in place. Our quick-connect function was developed primarily based on confirmed applied sciences from our greater than 30 years of expertise in safety-critical gas emissions venting.
