<p><P>PROBLEM TO BE SOLVED: To provide a battery device capable of cooling each battery cell sufficiently. <P>SOLUTION: A surface of a battery cell contacting to air circulating in a vent hole with at least two of whole battery cells from an inlet side is made smaller than the other battery cells. With this, air circulating through an upstream side of an air path in the vent hole is prevented from being overheated by the battery cells, and since air circulating through a downstream side of the air path in the vent hole is contacted to a large area with the battery cells, the battery cells located at the down stream side of the air path is sufficiently cooled. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
