<p><P>PROBLEM TO BE SOLVED: To provide a power supply device capable of being used for a battery module at all structures and minimizing fluctuationΔT of a battery temperature between the battery with the highest temperature and the battery with the lowest temperature in the battery module. <P>SOLUTION: The power supply device 38 includes a plurality of square batteries 18 having negative and positive electrode terminals 21, 22, a battery module 17 electrically connected by laminating the plurality of square batteries 18, and a cooling mechanism for cooling the square batteries 18. Then, the battery module 17 is laminated by assembling the plurality of square batteries 18 which are different in calorific values and cooling characteristics. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
