<P>PROBLEM TO BE SOLVED: To provide a battery pack capable of lowering the height, miniaturizing, and uniformly cooling the whole of a battery module. <P>SOLUTION: The battery pack is equipped with the battery module 10 constituted by stacking a plurality of battery cells; an inside suction duct 8 for supplying a refrigerant introduced in a casing through a refrigerant induction port 8a in the direction of the battery module; and an inside exhaust duct 9 for exhausting the refrigerant led in from the direction of the battery module to the outside of the casing through a refrigerant exhaust port 9a, the refrigerant lead-in port and the refrigerant exhaust port 9a are installed on the same side of the casing, the refrigerant lead-in port leads in the refrigerant passing through the refrigerant lead-in port in the first direction, the inside suction duct has a stream lining means for deflecting the refrigerant led in from a lead-in port of the inside suction duct in the second direction substantially crossing at right angles to the first direction. Each battery cell has many flow passages through which the refrigerant flows between the adjoined cells, and a means 78 equalizing the flow speed of the refrigerant flowing through the flow passage is installed in the battery module. <P>COPYRIGHT: (C)2007,JPO&INPIT |
