摘要： A fire extinguishing system for an energy storage device having a battery rack for a battery module, the fire extinguishing system including a sensing unit configured to detect when a value of one or more of a temperature of the battery module, a voltage of the battery module, or a level of smoke from the battery module is higher than a preset threshold value; and a fire extinguishing unit configured to provide a fire extinguishing agent to the battery module when the sensing unit detects that the value is higher than the preset threshold value, the fire extinguishing unit including a heat-sensitive member. The heat-sensitive member is positioned at a battery cell vent hole for a battery cell in the battery module. The heat-sensitive member is configured to allow the fire extinguishing agent into the vent hole by being melted when a temperature of the heat-sensitive member is higher than a predetermined temperature.
