摘要： Multi-function valve assemblies are provided for use in automotive components, such as traction battery packs, for example. An exemplary multi-function valve assembly may include a valve housing, a first valve body movably positioned within the valve housing, and a second valve body movably positioned within the valve housing. The first and second valve bodies may be moved between positions in which the valve bodies are seated against one another and other positions in which the valve bodies are unseated relative to one another to provide various valve functions. The multi-function valve assembly may be configured to provide functions such as degassing, pressure equalization, leak testing, etc.

摘要： A traction battery assembly includes an array housing that houses battery cells, and a filter layer permitting a flow of gas vented from at least one of the battery cells to an area outside the array housing. The filter layer blocks a flow of particulates vented from the at least one battery cell to the area outside the array housing.
