Abstract: A battery pack has a casing, electric fans, battery temperature thermistors and a battery management unit. The casing accommodates the battery cell stacks. The electric fans generate an air circulation in the inside chamber of the casing. The thermistors detect a temperature of the battery cells. At least one of the thermistors is arranged in each of the battery cell stack to detect a temperature of a battery cell arranged at a specific location in a battery cell stacking direction. At least one of the thermistors arranged in one battery cell stack in a pair of the battery cell stacks selected from all of the battery cell stacks detects a temperature of the battery cell arranged at a different location in the battery cell stacking direction from a location of any battery cell arranged in the other battery cell stack in the pair of the battery cell stacks.

Abstract: A first fin is formed on a first inside wall surface to protrude therefrom. The first fin exchanges heat between fluid and the first inside wall surface. A first fluid passage is divided between a first region that is a space where the first fin is arranged, and a second region that is a space where the first fin is not arranged. Fluid flows from the second region into the first region. The first fin includes an inflow port through which fluid flows into the first region, and an outflow port through which fluid flows out of the first region. The first fin is formed to extend from the inflow port to the outflow port. An area of the inflow port is larger than a cross-sectional area of the first fluid passage when viewed in a flow direction of fluid.

Abstract: A battery pack includes a housing accommodating a plurality of batteries and a blower. A control unit manages the temperature of the batteries according to the battery temperature provided by a temperature detector. When the battery temperature becomes equal to or higher than a predetermined cooling required temperature, the control unit executes a cooling mode of operating the blower to cool the batteries. The control unit executes a temperature equalizing mode of operating the blower to equalize the temperature inside the housing by causing the fluid flowing through the circulation path even when the battery temperature is lower than the cooling required temperature and the cooling is unnecessary.
