Abstract

A method for calculating the state of health in a secondary battery comprises the following steps: (a) calculating the amount of current of the secondary battery by means of integrating charging/discharging currents of the secondary battery; (b) verifying the charging/discharging state of the secondary battery by inspecting the charging/discharging state or no-load state of the secondary battery; and (c) calculating the state of health in the secondary battery by using the amount of current in the secondary battery, which is calculated from step (a), when the charging/discharging of the secondary battery of step (b) is completed. According to the present invention, an accurate calculation/deduction of the state of health of the secondary battery is enabled based on charging/discharging amounts, unlike existing methods of accurately calculating/deducting the state of health of the secondary battery.
