Abstract

The present invention provides a charging apparatus comprising: a current measurement module for measuring a current flowing in a secondary battery during charging and discharging of the secondary battery; a charging and discharging module including first and second charging units which supply charging pulses for charging the secondary battery and are connected in parallel to each other, and first and second discharging units which supply discharging pulses for discharging the secondary battery and are connected in parallel to each other; and a control module which supplies first and second control signals to the first and second charging units and the first and second discharging units to charge and discharge the secondary battery and checks whether the first and second charging units or the first and second discharging units are normally operated when the current measured by the current measurement module is lower than a set reference charging current or a set reference discharging current.

Abstract

The present invention provides a method for operating a charging device, comprising the steps of: supplying charging pulses for charging a secondary battery; and, while supplying the charging pulses, supplying discharging pulses for discharging the secondary battery in between the charging pulses, wherein the charging pulses and the discharging pulses are alternately supplied since the start of the activation of the secondary battery.
