Abstract: 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 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.

Abstract: Provided is a battery module mounting tray that may dampen impacts and vibrations, which may occur during the transportation of a battery module, by including a bracket to fix a side of the battery module. A battery module mounting tray includes: a bottom plate configured to support a plurality of battery modules to be seated thereon; and a bracket located on the bottom plate to fix the plurality of battery modules, and the bracket includes a first support unit to support a first side of the plurality of battery modules, a second support unit bent from both ends of the first support unit to support a portion of a side adjacent to the first side and located at an outermost side, and a third support unit extending away from a central region of the first support unit to support between the plurality of battery modules.
