US 2017/0304662 A1 · Extinguishing Method and Extinguishing Device for Introducing at Least One Extinguishing Agent into a Battery

Abstract

A method for introducing at least one extinguishing agent into a battery, in particular into a high-voltage battery for a motor vehicle. The at least one extinguishing agent is introduced into a housing of the battery that is at least partially sealed against the penetration of water, in which a plurality of battery cells are arranged. For this purpose, a through-opening is created in a partial region of a wall of the housing, wherein the partial region is penetrated by means of an end region of an extinguishing device. At least one extinguishing agent is introduced into the housing of the battery through a supply channel of the extinguishing device. In addition, the invention relates to an extinguishing device.
