Abstract: 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.

Abstract: The electronic device includes a main battery that supplies electric power to a load circuit, a sub-battery that supplies electric power to the load circuit in a case where the main battery is detached from the electronic device, a first charging circuit that charges the main battery, a second charging circuit that charges the sub-battery, and a controller that controls the first and second charging circuits. The controller changes a setting value of a charging electric current for the sub-battery in the second charging circuit based on an amount of charge of the main battery.
