Abstract

A traction battery for a motor vehicle includes a plurality of battery cells which are electrically connected to one another, a battery housing which houses the battery cells, several degassing elements for conducting gas away out of the battery housing in the case of a cell outgassing, a sensing system for localizing the cell outgassing, and a control unit which, in the case of a cell outgassing, actuates the degassing elements such that the degassing element situated nearest the cell outgassing remains closed and one or more of the degassing elements that are farther away from the cell outgassing is/are opened.
