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.

Abstract: A battery pack includes a secondary battery, a state of charge calculator, an integrated current amount calculator, a differential state of charge calculator, a full charge capacity calculator, and a charging-and-discharging control section. The differential state of charge calculator calculates a differential state of charge between a first state of charge at a first detection timing and a second state of charge at a second detection timing. The integrated current amount calculator calculates an integrated amount of a current flowing to the secondary battery in a subject period from the first detection timing to the second detection timing. The full charge capacity calculator calculates a full charge capacity of the secondary battery based on the differential state of charge and the integrated current amount. The charging-and-discharging control section is configured to restrict one of the charging and the discharging of the secondary battery during the subject period.
