The present invention relates to a power storage apparatus using an integrated cooling method, and more specifically, to a power storage apparatus using an integrated cooling method, comprising battery modules, a rack, a refrigerant duct and suction fans. Each battery cell module is formed in such a manner that a unit cell arrangement body having a structure, in which at least two battery cells or unit cells formed in a unit module are stacked, is mounted on a battery module case having a hexahedral shape. The rack has a lattice structure where module reception parts are included in two rows in the height direction, the module reception parts allowing the battery modules to be mounted thereon in an insertion manner, respectively. The refrigerant duct is coupled to a rear wall of the rack based on the positions of electrode terminals of the battery modules, is assembled to have a structure where at least two duct unit bodies are connected in the height direction, the duct unit bodies allowing refrigerant passing through the module reception part in each row to be introduced, and has refrigerant outlets formed on upper ends or lower ends of the assembled duct unit bodies to discharge the refrigerant. The suction fans are mounted on the outlets of the refrigerant duct. |
