<P>PROBLEM TO BE SOLVED: To provide a battery pack case. <P>SOLUTION: A battery pack case includes: at least one or more battery cells; a cooling case in which insertion portions into which the battery cells are inserted are formed in an inclined manner; and a cooling passage provided in the cooling case, and formed in an inclined manner so that a cooling medium is flown into between the battery cells. According to the battery pack case, front faces of the battery cells except for connection terminals are in contact with the cooling passage and a uniform amount of the cooling medium is supplied to the respective battery cells, to improve cooling efficiency for the battery cells, allowing a service life of the battery cells to be elongated. The cooling medium supplied by the cooling passage formed in an inclined manner is automatically flown due to the height difference, allowing a power source for the flowing to be eliminated. The battery cells are inserted by a slide system, to simplify a manufacturing process, when the battery cell is replaced, allow only the corresponding battery cell to be replaced, and simplify maintenance. <P>COPYRIGHT: (C)2013,JPO&INPIT |
