System and method for extinguishing fire in high voltage battery for vehicle

Abstract

A system and a method for extinguishing a fire in a high voltage battery for a vehicle, which supply cooling water flowing in an upper portion of a high voltage battery to the high voltage battery when a fire occurs in the high voltage battery, extinguishing the fire, include a battery cell assembly, an upper cooling passage which is provided in an upper portion of the battery cell assembly and through which cooling water flows, an upper plate including at least one through-hole and disposed between the battery cell assembly and the upper cooling passage to separate the battery cell assembly and the upper cooling passage, and solderings disposed in the at least one through-hole in the upper plate at intervals and configured to be melted at a predetermined temperature. When a temperature of the battery cell assembly due to the fire is predetermined temperature or higher, the solderings are melted and the cooling water is supplied to the battery cell assembly.
