PRESSURE RELEASE VENT FOR BATTERY MODULE

A battery module has battery cells and a housing. The housing includes a first end plate, a second end plate, a first side plate, and a second side plate. The battery cells are disposed between the first end plate, the second end plate, the first side plate, and the second side plate. A cover is disposed at least partially over the first end plate, the second end plate, the first side plate, and the second side plate. A pressure release vent couples to the housing and includes an interior surface that defines a plurality of sections that are configured to dislodge from the pressure release vent based on a pressure within the battery module exceeding a pressure threshold. The individual sections pivot about segments during rupture of the pressure release vent.
