<P>PROBLEM TO BE SOLVED: To improve arrangement efficiency of a battery module. <P>SOLUTION: A battery module 10 of a power supply device 1 is formed by arranging plural square batteries 11 in a thickness direction of the square batteries 11. Spacers 21 are arranged between the respective square batteries 11, and an upstream passage and a downstream passage for circulating a heat medium are formed on a first face in a direction opposed to one face of the spacer 21 in the thickness direction of the square battery 11. The spacers 21 are arranged between the respective square batteries 11, and therefore, a supply circulation part and an exhaust circulation part for circulating the heat medium are formed between the respective square batteries 11. Then, a duct 30 constituted by stacking a supply passage 32 and an exhaust passage 33 is arranged on one side of the battery module 10 in a width direction of the square battery 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
