1. A vehicle, comprising:
a store provided for storing electrical energy, the store having a store housing in which multiple electrical storage cells are arranged, and
a device provided in the store housing through which gas escaping from one or more of the storage cells into an interior of the store housing escapes outward from the store housing into surroundings, wherein
the device includes a purely mechanical acoustic signal generator provided for generating an acoustic warning signal in an event of the escaping gas flowing through the device, wherein the warning signal is generated merely by way of the gas throughflow of the escaping gas, and
the device is arranged such that the escaping gas that flows through the device impacts a component of the vehicle body, whereby the vehicle body is caused to perform acoustic oscillations and amplify a sound intensity of the warning signal.
