Abstract
Disclosed is a technique capable of improving the life span of a battery by managing the charging of the battery. The battery charging management apparatus includes a degradation rate estimating unit configured to estimate a degradation rate of a secondary battery; a ceiling calculating unit configured to calculate a charge ceiling voltage based on the degradation rate estimated by the degradation rate estimating unit; a charge control unit configured to control the charging of the secondary battery so that the secondary battery is charged only up to the charge ceiling voltage calculated by the ceiling calculating unit; and a memory unit configured to store information required for operating at least one of the degradation rate estimating unit, the ceiling calculating unit and the charge control unit.
