Abstract
A battery degassing unit for a battery housing has a base body that has a gas passage opening and is to be connected fluid-tightly to a pressure compensation opening of the battery housing. A first filter covers the gas passage opening at an inner side of the base body. The first filter is a separation grid with first grid openings. A second filter is a separation grid arranged between first filter and inner side of the base body and has second grid openings. The base body has fastening regions for fastening the battery degassing unit to the battery housing. One of the first and second filters completely engages across the gas passage opening. One of the first and second filters is a corrugated filter so that a length extension in a stretched state in at least one direction is at least 1.3 times as large as in a corrugated state.
