<P>PROBLEM TO BE SOLVED: To provide a battery pack device having a plurality of unit cells suppressed in uniform temperature. <P>SOLUTION: A first unit cell group includes a plurality of unit cells, each of which has a rectangular thick plate-like shape and the plurality of the unit cells are arranged side by side in one direction so that side surfaces thereof are opposed to each other. A second unit cell group includes the same constitution as the first battery group and is separated from the first unit cell group, wherein a back surface and a belly surface or back surfaces or belly surfaces are arranged opposite to each other. A member having thermal capacity is provided between side surfaces of the plurality of the unit cells for respective first and second unit cell groups. A compressive force giving mechanism gives a compressive force so that a first unit cell located at the outermost position out of the plurality of the unit cells for the respective first and second unit cells, and a second unit cell located at the outermost position on the side opposite to the first unit cell are displaced in a direction approaching each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
