Abstract: A flow passage device includes a circulation flow passage, a swing valve provided in the circulation flow passage, an energizing part, and a lock mechanism including a lock pin. The lock pin is configured so as to hinder the swing valve from opening, and to allow the swing valve to open. The swing valve is configured so as to rotate from a first valve position to a second valve position. The lock mechanism is configured so as to set a locked state and to set an unlocked state. The lock pin is configured so as to protrude as being energized by pressure of the fluid on an upstream side of the swing valve, and to retract as being energized by pressure of the fluid on a downstream side of the swing valve.

Abstract: A connection unit of the present invention includes: a rail member extending in a direction where a plurality of storage elements is aligned; and a plurality of bus bar units each including an engagement portion movable along the rail member in the predetermined direction, and a bus bar fixed to electrode terminals of the storage elements adjacent to each other in the predetermined direction and connected to the engagement portion. The plurality of bus bar units engages with the rail member so as to be aligned in the predetermined direction, and the bus bar units adjacent to each other are provided so as to be movable independently along the predetermined direction. Entire assembly tolerance in the plurality of storage elements aligned in the predetermined direction can be absorbed (permitted) by adjusting distances between the independent bus bar units, thereby making it possible to easily assemble the plurality of bus bars.

Abstract: A battery pack includes: a cell stack; a first duct and a second duct configured to feed cooling air toward the cell stack; and a housing case. The first duct and the second duct extend in a first direction and are spaced apart from each other in a second direction, the first direction being parallel to a front-back direction of a vehicle in a mounted state in which the battery pack is mounted on the vehicle, the second direction being parallel to a width direction of the vehicle in the mounted state. The first duct is arranged on an outer side of the cell stack on one side in the second direction, and the second duct is arranged on an outer side of the cell stack on the other side in the second direction.

Abstract: In a temperature adjusting structure for an electric power storage device as well as in a temperature adjusting method for an electric power storage device, a temperature adjusting air that exchanges heat with a case in which an electric power generation element is housed is guided in a longitudinal direction of a circulation path. Then, a vortex flow that swirls with the longitudinal direction being a rotational axis is generated in the air that flows through the circulation path, and the vortex flow is brought into contact with a lateral surface of the case.

Abstract: In a temperature regulation structure according to the invention, the power storage element includes a power generation element for charging and discharging, and has a case body having an opening portion for incorporating the power generation element, and a lid that closes up the opening portion of the case body. Air for temperature regulation that comes into contact with the power storage element is supplied from a direction substantially perpendicular to a bottom face of the case body, which is opposed to the lid across the power generation element. The temperature of the power storage element can be efficiently regulated by bringing the air for temperature regulation into contact with the bottom face of the case body.
