<p><P>PROBLEM TO BE SOLVED: To provide a battery pack capable of suppressing increase in the number of parts, and forming a flow passage of a heat medium. <P>SOLUTION: The battery pack 1 is constituted of a plurality of batteries 10, bus bars 11 to 13, and an insulating member 14. The batteries 10 have a terminal protruding upward from the upper face of a case 100. Plate-shaped bus bars 11 to 13 to electrically connect the plurality of batteries 10 are connected to the upper end parts of the terminal. The plate-shaped insulating member 14 to insulate between the bus bars 11 to 13 is extended between the bus bars 11 to 13. Then, the flow passage is sectioned by the upper face of the case 100, the bus bars 11 to 13, and the insulating member 14, and a cooling medium is circulated between these. For that reason, there is no need of installing a member for forming the flow passage separately. Accordingly, increase in the number of parts is suppressed, and the flow passage for the cooling medium can be formed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
