Fire safety and extinguishing system for an electrical energy storage system

Abstract

A fire safety and extinguishing system for an electrical energy storage system includes at least one sensor for detecting a hot spot abnormality in the electrical energy storage system; a fire extinguisher installed inside a housing of the electrical energy storage system, wherein the fire extinguisher is configured to dispense an extinguishing agent when a hot spot abnormality in the electrical energy storage system is detected; a liquid separator arranged to receive an ethylene glycol and water mixture from a cooling reservoir, and to separate water from glycol. An outlet of the liquid separator is fluidly connected to an inlet of the housing of the electrical energy storage system to provide pressurized extracted water to the fire extinguisher as the extinguishing agent.
