CHARGING APPARATUS, POWER STORAGE APPARATUS, AND POWER SOURCE APPARATUS
First Claim
1. A charge apparatus that charges a secondary battery, the charge apparatus comprising:
- an estimation portion that estimates a use start time of the secondary battery based on a use history of the secondary battery;
a charge allowable time calculation portion that calculates a time period from a charge start time of the secondary battery to the nearest habitual use start time as a charge allowable time period;
a necessary charge time calculation portion that calculates a necessary charge time period necessary to fully charge the secondary battery; and
a charge execution portion that performs a temporary suspension of the charge during the charge and charges the secondary battery such that the secondary battery is fully charged within the charge allowable time period when the charge allowable time period exceeds the necessary charge time period.

Abstract
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.
