Abstract:
1. An electronic device, comprising: circuitry configured to: receive at least information on a full-charge capacity of a currently inserted battery apparatus having secondary cells in a brand-new state, a battery charge/discharge cycle count of the battery apparatus, and a first correction coefficient specific to the battery apparatus transmitted from the battery apparatus; retain a plurality of second correction coefficients, each of the second correction coefficients representing a degree of wear of the battery apparatus per one battery charge/discharge cycle; calculate an average current value and a peak current value of detected current values for a charge/discharge current flowing through the battery apparatus; dynamically select one of the plurality of the second correction coefficients based on the calculated average current value and the calculated peak current value; and calculate a current full-charge capacity of the battery apparatus using the information on the full-charge capacity of the battery apparatus in a brand-new state, the battery charge/discharge cycle count, and the first correction coefficient, which are transmitted from the battery apparatus, and the selected second correction coefficient.
