Abstract
A secondary battery charger system in which a chargeable power is calculated on the basis of a difference between a charging target voltage and a cell voltage using a charging control unit that controls a charger used to charge a secondary battery, the secondary battery charger system including a charging threshold voltage setting unit configured to set the charging target voltage to be lower than a charging limitation voltage which is an upper limitation of the cell voltage allowable in design. The charging control unit stops the charging if a predetermined charging stop condition is satisfied while the cell voltage exceeds the charging target voltage and is lower than the charging limitation voltage.
