Abstract
A charging controller includes a current measurement unit configured to measure a charging current of a rechargeable battery, a detection unit configured to detect switching from a constant current charge to a constant voltage charge based on the charging current measured by the current measurement unit, during charge of the rechargeable battery, and an update unit configured to update a full charge capacity of the rechargeable battery based on a charged capacity after the point in time, detected by the detection unit, of switching from the constant current charge to the constant voltage charge.
