Abstract
An extinguishing system for a high-voltage battery of a motor vehicle, including at least one extinguishing agent container with a gaseous extinguishing agent; a seal for sealing the extinguishing agent container, which prevents an outflow of the extinguishing agent into the interior of the high-voltage battery; a control device interacting with the seal device, designed to open the seal upon the incidence of a triggering signal, thus allowing the extinguishing agent to flow into the interior of the high-voltage battery and to displace any air included therein; an auto-ignition mechanism that interacts with the seal, which auto-ignites at a certain auto-ignition temperature and opens the seal.
