The present disclosure provides a control device for a secondary battery, and the control device includes a controller configured to correct battery characteristics on an open circuit voltage to a remaining capacity of the secondary battery. In the control device for the secondary battery, the controller acquires data of a plurality of open circuit voltages in the battery characteristics during charging the secondary battery. When the secondary battery is fully charged, the controller corrects the open circuit voltages between respective pairs selected and combined from at least one part of the data of the plurality of open circuit voltages. The controller weighted-averages and corrects full charge capacities, which are calculated by the correction of the open circuit voltages between the respective data pairs, with differences each between respective remaining capacities each corresponding between the respective data pairs.

Control device for secondary battery to correct battery characteristics on open circuit voltage to remaining capacity

An electronic device comprises a main battery used as a drive power source for driving the electronic device, a secondary battery used as a drive power source instead of the main battery when the main battery cannot be used, a battery detection unit that detects an event of removal of the main battery from the electronic device, and a power control unit that changes the drive power source from the main battery to the secondary battery and controls operation of the electronic device to reduce power consumption by the electronic device when removal of the main battery is detected by the battery detection unit.
