摘要： A battery pack to be mounted in a vehicle incorporates a battery stack and a cooling fan. An air intake is formed in a side face located in the vicinity of the cooling fan. In consideration of passengers entering and exiting the vehicle, the air intake is formed as well in a plane generated as a result of removal of a corner. A louver for preventing intrusion of extraneous matter is disposed at the front of the air intake. A decrease in the amount of cooling air induced by the louver is lessened by means of forming the air intake in the plane.

摘要： A battery cell includes a battery housing case formed with a through hole communicating with an interior space, a hollow rivet, and a seal rubber. The hollow rivet has a seal surface annularly extending outside the battery housing case, and a hollow portion formed with an exhaust port continuous to the inner edge of the seal surface and positioned at the through hole to allow gas in the interior space to flow out through the exhaust port. The seal rubber has a contact unit extending annularly facing the seal surface to press the seal surface and is provided so as to close the exhaust port. The contact unit is formed to project toward the seal surface so as to contact the seal surface at a position away from the inner edge of the seal surface. Such an arrangement prevents an electrolyte leakage over a long period of time.

摘要： In a battery pack where a fan is housed within a case housing a battery stack, the noise generated from turbulence of a medium that is supplied and exhausted between a fan opening of the fan and the battery stack is reduced. The battery pack has a battery stack, a cooling fan installed adjacent to the battery stack and having a fan opening formed in a top surface for taking in cooling air after cooling the battery stack, an upper case for covering the upper part of the battery stack and the cooling fan, and a junction duct for guiding the cooling air after cooling the battery stack to the fan opening. The junction duct is formed from the duct lower unit having an opening formed at a location facing the fan opening and one wall of the upper case in contact with a lower end and periphery of the duct lower unit.
