Abstract: A temperature detection unit includes a board-shaped housing having a board side face provided with a recess configured to be fitted with a side edge of a conductive board disposed between a plurality of stacked power storage modules, and a temperature detection sensor mounted on the housing and configured to measure a temperature of the power storage modules. The housing is provided with a sensor accommodating recess accommodating the temperature detection sensor. A plate end face on one side facing an intersecting direction with a direction that the board side face of the housing faces is provided with an opening configured to allow a temperature wire connected to the temperature detection sensor to extend toward the outside. The sensor accommodating recess extends obliquely to approach the conductive board from one side toward the other side in the intersecting 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.
