a safety module that includes a cooling/heating unit that stores a cooling/heating medium therein and an extinguishing unit that stores an extinguishing medium therein; a first circulation channel that interconnects the battery module and the safety module to circulate the cooling/heating medium or the extinguishing medium between the battery module and the safety module; and a battery management system that measures the temperature and pressure of the battery module and opens the cooling/heating unit or the extinguishing unit to supply the cooling/heating medium or the extinguishing medium to the first circulation channel when the temperature and pressure of the battery module reaches a preset value. ## Claims ### Claim 1 An energy storage system comprising: a battery module, to which a plurality of hollow secondary batteries, each of which has a hollow pipe therein, are connected; a safety module that comprises a cooling unit that stores a cooling medium and a fire extinguishing unit that stores a fire extinguishing medium; a first circulation passage that interconnects the battery module and a safety module such that the cooling medium or the fire extinguishing medium circulates between the battery module and the safety module; and a battery management system that measures a temperature and a pressure of the battery module such that the cooling medium or the fire extinguishing medium is supplied to the first circulation passage by opening the cooling unit or the fire extinguishing unit when the temperature and the pressure of the battery module reaches preset values. ### Claim 2 (depends on 1) The energy storage system of claim 1, wherein the first circulation passage comprises: a first passage that interconnects one end of the safety module and a pipe of the hollow secondary battery, which is located at one end of the battery module; and a secondary passage that connects an opposite end of the safety module and a pipe of the hollow secondary battery, which is located at an opposite end of the battery module. ### Claim 3 (depends on 1) The energy storage system of claim 1, wherein the fire extinguishing medium is any one of water, loaded stream liquid, chemical bubbles, air bubbles, carbon dioxide, a halide, sodium hydrogen carbonate, potassium hydrogen carbonate, urea potassium hydrogen carbonate, ammonium phosphate, and aqueous film forming bubbles. ### Claim 4 (depends on 1) The energy storage system of claim 1, wherein the cooling medium is any one of cooling air and a cooling solution. ### Claim 5 An energy storage system comprising: a housing; a battery module that comprises a plurality of hollow secondary batteries, each of which has a hollow pipe therein, and is installed in the interior of the housing to be spaced apart from each other; an air conditioner that is installed between the battery modules to generate air, of which a temperature has been adjusted; and second circulation passages that connect the air conditioner and the plurality of battery modules such that air generated by the air conditioner circulates between the battery modules and the air conditioner. ### Claim 6 (depends on 5) The energy storage system of claim 5, wherein the second circulation passages comprise: a third passage that is branched to a plurality of passages on one side of the air conditioner to be connected to sides of the battery modules; and fourth passages that extend from opposite sides of the battery modules towards the air conditioner. ### Claim 7 (depends on 6) The energy storage system of claim 6, wherein fifth passages that extend to the outside of the housing are installed at sides of the fourth passages and vents that selectively open or close the fifth passages are installed in the fifth passages. ### Claim 8 (depends on 6) The energy storage system of claim 6, wherein the fourth passages merge into one pipe at a specific location for simplifying the structure thereof and smoothing flows of air and extend to the air conditioner. ### Claim 9 (depends on 5) The energy storage system of claim 5, wherein a fire detector is installed in the interior of the housing. ### Claim 10 (depends on 5) The energy storage system of claim 5, further comprising: a safety module that is installed on one side of the air conditioner such that the air conditioner supplies the cooling medium and/or the fire extinguishing medium together with air to the battery modules by supplying the cooling medium and/or the fire extinguishing medium to the air conditioner when a fire occurs. ### Claim 11 (depends on 10) The energy storage system of claim 10, wherein the fire extinguishing medium is any one of water, loaded stream liquid, chemical bubbles, air bubbles, carbon dioxide, a halide, sodium hydrogen carbonate, potassium hydrogen carbonate, urea potassium hydrogen carbonate, ammonium phosphate, and aqueous film forming bubbles.
