The present invention relates to a battery pack in which a cooling passage is formed. The technical problem to be solved of the present invention is to provide a separate component or to increase the strength without increasing the thickness to prevent the swelling phenomenon, to improve the cooling efficiency to minimize the deterioration phenomenon, to control the cooling efficiency for each region By optimizing the battery performance, all battery cells have a uniform temperature.n n n To this end, the present invention provides a battery housing having at least one coupling groove, a peripheral region near the at least one coupling groove, and a plurality of cooling passages extending in at least one direction of the at least one coupling groove in the peripheral region, and at least one. Disclosed is a battery pack comprising a battery cell housed in a coupling groove of a.n n n n HEV, battery housing, battery case, cooling flow path, thermal screen member, battery pack |
