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.
Claims10
A traction battery for a motor vehicle, the traction battery comprising:
- a plurality of battery cells which are electrically connected to one another;
- a battery housing which houses the battery cells;
- a plurality of degassing elements for conducting gas out of the battery housing in a case of a cell outgassing;
- a sensing system for localizing the cell outgassing;
- and
- a control unit which, in the case of the cell outgassing, actuates the degassing elements such that a first degassing element situated nearest the cell outgassing remains closed and one or more other degassing elements that are farther away from the cell outgassing are opened.
A method for controlling degassing elements for conducting gas out of a battery housing of a traction battery for a motor vehicle, the method comprising:
- identifying a cell outgassing;
- localizing the cell outgassing by a sensing system;
- actuating the degassing elements such that in a case of the cell outgassing, a first degassing element situated nearest the cell outgassing remains closed and one or more other degassing elements that are farther away from the cell outgassing are opened.
