<P>PROBLEM TO BE SOLVED: To provide a bus bar module for a battery pack in which excessive high temperature of a bus bar can be prevented. <P>SOLUTION: A first air hole 11 and a second air hole 73 that form air path penetrating from the upstream to the downstream in a preset air cooling direction R1 are formed in parts that surround hollow parts of a plurality of bus bar housing parts 20 in a bus bar 10, a fenced part 21, and lid member 70. When the air cooling direction R1 is a direction in which an electrode extends from a battery cell, the first air hole 11 is formed in a part that is located in a gap of adjacent battery cells in each of the bas bars 10, and the second air hole 73 is formed in the lid member 70. <P>COPYRIGHT: (C)2012,JPO&INPIT |
