1. 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 plurality of battery cells;
a plurality of degassing elements that are configured to conduct gas out of the battery housing in a case of a cell outgassing;
a sensing system that, in the case of the cell outgassing, is configured to localize the cell outgassing and to send detection signals to a control unit; and
the control unit which, in the case of the cell outgassing, is configured to receive the detection signals from the sensing system and to send control signals to actuate 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.
