Abstract

In a charging method of a battery, at each of a first time point and a second time point after a time point at which a predetermined time is elapsed from the first time point, a superimposed current obtained by superimposing a current waveform that periodically changes at a predetermined frequency on a charging current is input to the battery, thereby measuring, concerning an impedance of the battery at the predetermined frequency, a first impedance at the first time point and a second impedance at the second time point. In the charging method, using a parameter representing an increase state of the second impedance to the first impedance as an index, a current value of the charging current is adjusted.
