<p>A power supply device includes a battery block 3 of battery cells 1. Cooling gaps 4 are provided for flowing cooling gas between cells 1 from a side surface of the block 3 into the gaps 4. The width of a temperature equalizing plate 15 covering the side surface of the block 3 varies designed so that the amounts of the gas flowing into the gaps 4 are reduced toward the upstream side. The upstream side of the plate 15 is fastened to the block 3. The plate 15 includes protrusions 37 that protrude from the downstream side of the plate 15. Insertion portions 39 are arranged at positions of coupling members 11 corresponding to the protrusions 37 on side surface of the block 3. When the protrusions 37 of the plate 15 are inserted into the insertion portions 39, the plate 15 is attached to the coupling members 11.</p> |
