<P>PROBLEM TO BE SOLVED: To cool battery packs which are arranged in a plurality of columns to uniform temperature. <P>SOLUTION: A flow control plate 13 provided upstream from the battery packs is constituted by successively providing unit current plates 131 extending in a battery length direction, and first and second through holes 132 are bored in the flow control plate. While the unit current plates 131 are provided to battery modules 2 in the most upstream colum in such a shape that upstream top surfaces of the battery modules 2 are covered, first through holes 132a for introducing cooling air in the respective most upstream column battery modules are provided to the unit current plates 131, and parts where ends of the successively provided unit current plates adjoin each other serve as second through holes 132b. The second through holes are provided in spaces between the mutually adjacent most upstream-side battery modules, and configured such that the cooling air introduced through the second through holes does not reach battery modules in a top stage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
