Early fire detection system for an ess battery module

Abstract

The present disclosure relates to a system for early detection of fire in an ESS battery module, particularly to a system capable of early fire detection of a battery module inside an ESS including: an air suction-type detector that is fitted to the exterior of the ESS and detects fire by introducing gas inside the ESS battery module; a suction line, of which one end is connected to the ESS battery module, sucks gas inside the ESS battery module in real time and introducing the gas into the air suction-type fire detector; a suction pump that is fitted to one side of the suction line and supplies power for drawing air from inside the ESS battery module into the suction line; and a multiple sensing unit that is fitted to one side of the suction line and senses a temperature of the gas introduced through the suction line, as well as any generated gas. The system is capable of early fire detection for an ESS battery module by primarily sensing the signs through a suction line of an air suction-type detector, using a detection sensor in a multiple sensing unit and secondarily monitoring smoke in the air suction-type detector, when signs (CO, CO2, VOCs) of thermal runaway are generated in the ESS battery.
