A battery pack includes a battery module housing configured to receive a plurality of battery cells, a battery pack case configured to receive one or more of battery module housings, a water tank located above the battery module housings, and a heat sink located under the battery module housings. At least a portion of the surface of the battery module housing that faces the water tank is open, whereby, when fire breaks out in the battery cell, it is possible to rapidly and accurately prevent spread of flames of the ignited battery cell.

An energy storage system includes a rack having a space inside, a plurality of modules in the space of the rack, each of the plurality of modules including a plurality of battery cells arranged in one direction therein, and a sensing line along one side of the plurality of modules.

A battery module includes a plurality of battery cells; a module housing configured to accommodate a cell stack including the plurality of battery cells; and a sprinkler provided through the module housing at one side of the cell stack in a stacking direction, and the sprinkler includes a coupler positioned at an outer side of the module housing and connected to a supply tube that supplies a cooling fluid; a sprinkler head positioned at an inner side of the module housing and connected to the coupler; and an insulation cover assembly having an insulation cover configured to cover the sprinkler head and an impeller assembly configured to cover an opening formed at one side end of the insulation cover in a longitudinal direction.

A fire extinguishing apparatus of a vehicle is capable of effectively extinguishing a fire by uniformly and directly spraying a fire extinguishing agent in a wide range to a battery cell covered with an external structure in a vehicle. The fire extinguishing apparatus includes a cover, a spray nozzle, a controller, a driving device, and a fire extinguishing agent supplying device.

An appliance (10) for drying and/or washing laundry includes an autonomous fire extinction device (20). The fire extinction device has pipe (26) with an elongate shape and closed at both its longitudinal ends (26x). The pipe includes a fusible thermoplastic wall defining an internal space. The pipe is thermoformed to give it a particular shape in the unconstrained free state corresponding to its mounted position inside the enclosure (12). An extinguishing fluid (29) is inside the space, and is configured to be released by fusion of the pipe wall (26) under the effect of heat produced by a fire or an incipient fire.
