Abstract: A vehicle has a high-voltage store, which is provided for storing electrical energy, wherein the high-voltage store has a high-voltage store housing, in which a plurality of electrical storage cells are arranged, and a device is provided in the high-voltage store housing through which the gas escaping from one or more of the storage cells into the interior of the high-voltage store housing can escape outwards from the high-voltage store housing into the environment. The device has a purely mechanical acoustic signal generator which is provided in order to generate an acoustic warning signal when gas flows through the device, wherein the warning signal is generated merely by the gas flowing through.
