PROBLEM TO BE SOLVED: To provide a battery pack which improves the assemblability, inhibits rainwater and washing water from intruding into the interior, and improves the output performance of a battery.SOLUTION: In a vehicle battery pack 1, a battery 3 and a cooling fan 5 are housed in a case 2 in which an air intake port 24 and an exhaust port 25 are formed. The air intake port 24 is placed at an upper part, and the exhaust port 25 is placed at a side part of the case 2. A cooling fan duct 6 allows the cooling fan 5 and the exhaust port 25 to communicate with each other. An exhaust hood 7 is provided along an outer peripheral edge of the exhaust port 25 so as to enclose an area near the exhaust port 25. A passage opening/closing part 28, to which a valve 29 is attached, is provided in a cooling air exhaust passage 27 composed of the cooling fan duct 6 and the exhaust hood 7. |
