<p><P>PROBLEM TO BE SOLVED: To provide a battery pack capable of lowering temperature of each battery module by cooling wind. <P>SOLUTION: The battery pack is provided with battery modules 3, each of which 3 is equipped with a plurality of battery cells 16 each having a positive electrode terminal 26a and a negative electrode terminal 26b so as to pinch a battery cell body 32. The plurality of battery cells 16 are laminated, and at the same time, are serially connected as terminals 26a, 26b themselves are connected in turn. A connector 42a is provided for holding the 26a, 26b in a connected state, and is kept separated from a battery cell body layer 28 formed by the plurality of battery cells 16 to form air channels 50 for letting air pass between the battery cell body layer 28 and a connector 42A. With this, the terminals 26a, 26b of each battery cell 16 that are to be positioned in the air channels 50 are directly and positively cooled by air to effectively cool the inside of the battery cells 16. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
