<p>PROBLEM TO BE SOLVED: To effectively prevent drop in battery performance caused by temperature difference by uniformly cooling the whole of a plurality of power source modules housed in a holder case. SOLUTION: This power source device has a plurality of power source modules 1; the holder case 2; and a fan 9. The holder case 2 is a box having a first surface plate 2a and a second surface plate 2b on both surfaces, and a plurality of power source modules 1 are laterally arranged in parallel on the same plane. The holder case 2 has a partition 3 installed between plural lines of power source modules 1 laterally arranged, and the inside is partitioned in plural lines of sections 4. One line of power source module 1 is arranged in the section 4 of each line. The power source device lets flow divided air from an inflow port 13 of the first surface plate 2a to the plural lines of sections 4 with the fan 9, and air is discharged from an exhaust port 14 of the second surface plate 2b to cool the power source module 1 housed in each section 4.</p> |
