<p>PROBLEM TO BE SOLVED: To provide a battery pack which enables uniform cooling of the battery pack.SOLUTION: A battery pack 23 is formed by alternately laminating electric cells 77 and cooling plates 71. Vent holes 82b which penetrate through the cooling plate 71 are opened at each cooling plate 71, and multiple fins 83 are formed at both side end parts of the cooling plate 71. Cooling air is guided to an upper opening of each vent hole 82b by first cooling air guide plates 51, 53. Cooling air discharged from a lower opening of each vent hole 82b is guided to the fins 83 by a second cooling air guide plate 43. The cooling air guided to the fins 83 passes through spaces between the multiple fins 83 and then is discharged to the exterior of the battery pack 23.</p> |
