摘要

Provided are an energy storage apparatus and a method for cooling the energy storage apparatus, in which the energy storage apparatus includes a chamber including a receiving space therein, battery racks including a first battery rack group and a second battery rack group positioned in the receiving space and spaced apart from each other while facing each other with reference to a center of the receiving space, an upper duct positioned above the receiving space configured to supply cooling fluid to a cooling space which is a space between the first battery rack group and the second battery rack group, a cooling unit positioned outside the receiving space and configured to cool the cooling fluid, and a fluid moving member comprising a moving space where the cooling fluid heated after cooling the battery racks moves to the cooling unit, in which the cooling unit is supplied with the heated cooling fluid from the moving space, cools the supplied cooling fluid, and then supplies a resultant fluid to the upper duct.
