Abstract: The present disclosure is directed to an apparatus. The apparatus can include a first conduit coupled with the battery pack. The apparatus can include a first valve coupled with the first conduit. The first valve can allow gas to pass from the battery pack through the first valve at a first pressure. The apparatus can include a second valve coupled with the first conduit and with a second conduit. The second valve can allow the gas to pass at a second pressure. The second pressure can be greater than the first pressure. The apparatus can include a noise generating element coupled with the second conduit. The noise generating element can activate based on the second pressure.
