Eaton, a power management company, has recently unveiled a 3-in-1 battery pack vent valve for electric vehicle (EV) batteries. This valve is capable of three functions: leak-checking the battery case, and both passive and active venting to provide overpressure relief. The leak-check mechanism eliminates the need for a separate vent valve installation during battery assembly, and provides a more thorough testing of the sealing surface.
In addition, Eaton has developed a tool that allows manufacturers to actuate the leak-check mechanism on their assembly lines. This spring-based actuation allows for a range of opening pressure requirements with the same valve design, resulting in cost savings. The valve also features a low-flow breathing mode that allows air to move through porous material to normalize pressure during regular operation, and its resealing technology enables manufacturers to specify very low opening pressures.
According to Eaton Manager Jens Buhlinger, “Our new battery vent valve can be assembled both through our robust quick-connect feature or by a screwed metal-to-metal connection.” This new valve is expected to provide improved safety and reliability for EV batteries, while also reducing costs for manufacturers.
