A high-voltage accumulator has a high-voltage accumulator housing in which multiple electric storage cells are arranged. A wall of the high-voltage accumulator housing is equipped with at least one aeration/ventilation device which is gas-permeable at least from the interior of the high-voltage accumulator housing to the exterior of the high-voltage accumulator housing such that gas can leak out of the interior of the high-voltage accumulator in the event of an overpressure in the interior of the high-voltage accumulator housing. The aeration/ventilation device is equipped with a device, by which a substance that accumulates on the aeration/ventilation device and partly or completely blocks same can be removed.
