<P>PROBLEM TO BE SOLVED: To provide a battery pack increasing capacity of a bipolar battery, decreasing internal resistance of the battery, making requested high output and high energy compatible even when the battery pack constituted with bipolar batteries is used as a power source of a vehicle. <P>SOLUTION: The battery pack 1 is constituted by combining in parallel two kinds of batteries of bipolar batteries 3 and usual battery group 7 formed by connecting usual batteries 5 in series by the number of combinations of positive electrodes 13 and negative electrodes 15. The bipolar batteries have detecting tabs 9 connected to each unit cell layer to be constituted, and tab connecting parts 11 every series connection of the usual batteries at the same potential level as the detecting tab are electrically connected. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
