SECONDARY BATTERY CHARGING SYSTEM AND CHARGING METHOD

摘要

A secondary battery charging system wherein a charging control unit for controlling a charger for charging the secondary battery calculates chargeable power on the basis of the difference between a target charging voltage and a battery voltage. The secondary battery charging system has a charging threshold voltage setting unit for setting the target charging voltage to be lower than a charging inhibition voltage, which is the upper-limit of battery voltage allowed by the design of the battery. The charging control unit stops charging when a prescribed charging stop condition is met while in a state in which the battery voltage exceeds the target charging voltage but is lower than the charging inhibition voltage.
