Abstract
In a battery pack including rechargeable batteries arranged in parallel, a cooling medium path for allowing a cooling medium to horizontally flow be formed between the rechargeable batteries. A cooling medium delivery device for delivering the cooling medium to the cooling medium path is provided so as to reduce a height of the battery pack including a cooling device. The cooling medium delivery device is constituted by a pair of cooling medium introduction ducts provided on both right and left sides of the battery pack, each having delivery ports for delivering the cooling medium alternately in horizontally opposed directions to each of the cooling medium paths, and a cooling medium compression transport device for supplying the cooling medium to both of the cooling medium introduction ducts.
