A charging apparatus comprises an estimator unit for estimating the habitual usage start time of a secondary cell on the basis of the usage history of the secondary cell, an allowable charging time calculator unit for calculating the period of time from the charging start time of the secondary cell to the imminent usage start time as allowable charging time, a necessary charge time calculator unit for calculating the charging time necessary to fully charge the secondary cell as necessary charging time, and a charger unit for charging the secondary cell under degradation-suppression charging conditions when the allowable charging time exceeds the necessary charge time. Under the degradation-suppression charging conditions, the charging apparatus performs temporary charging suspension during charging, and charges the secondary cell so that full charge is reached within the allowable charging time.
