Abstract

A charging controller includes an internal resistance measurement unit configured to measure an internal resistance of a rechargeable battery multiple times over a charging period of the rechargeable battery; a detection unit configured to detect a peak of the internal resistance based on a change in the internal resistance measured by the internal resistance measurement unit; and an update unit configured to update a full charge capacity of the rechargeable battery referring to the peak of the internal resistance detected by the detection unit.
