CHARGING DEVICE AND METHOD FOR CONTROLLING SAME

摘要

Provided are a charging device for an alkali secondary battery capable of increasing charging efficiency, and a method for controlling the charging device. A method for controlling a charging device is characterized by monitoring the voltage value of an alkali secondary battery (1) while supplying the alkali secondary battery (1) with constant current, and suspending charging when the variation in the voltage value per unit time shifts from an increase to a decrease over time in the case where the voltage value exceeds a reference voltage value indicating the upper limit of the flat part of the curve that represents voltage value characteristics during charging for the alkali secondary battery (1).
