<P>PROBLEM TO BE SOLVED: To provide a cooling structure for an on-vehicle battery capable of preventing the variations in the degradation among the stacked batteries. <P>SOLUTION: A case 30 has a first air passage P1, a second air passage P2, and a third air passage P3. The first air passage P1 is extending through batteries 40 that are adjacent to each other in the longitudinal direction (X direction). The second air passage P2, which is communicating with one end of the first air passage P1, is partitioned and extending vertically between the batteries 40 and the inner wall surface 20a of a battery housing 20. The third air passage P3, which is communicating with the other end of the first air passage P1, is partitioned and extending vertically between the batteries 40 and the inner wall surface 20b of the battery housing 20. Fresh air is taken in from an air-intake 27 to the second air passage P2, the air-intake 27 being arranged on the battery housing 20 of a vehicle body, and the air being taken in from the air-intake 27 is discharged from an air-exit 28 arranged on the case 30 to outside through the second air passage 2, the first air passage P1, and the third air passage P3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
