<P>PROBLEM TO BE SOLVED: To provide a battery pack in which temperature unevenness between a passage surface in parallel with a cooling air passage of a battery and a surface perpendicular to the passage surface can be improved. <P>SOLUTION: In a battery pack 10, a plurality of batteries 1 are arranged while sandwiching a separator 7 having insulation properties therebetween, and the batteries 1 are cooled by blowing cooling air between the batteries 1. The separator 7 includes a cooling air passage 18, through which the cooling air passes, between a passage surface 17 of each of the batteries 1 and the separator, and a guide 9 is provided on an inlet side of the cooling air passage 18, the guide being disposed to face an inlet side end face 19 of each of the batteries 1 and introducing the cooling air into the cooling air passage 18. <P>COPYRIGHT: (C)2013,JPO&INPIT |
