Abstract: A charging/discharging test system includes a charging/discharging test device; and a controller to output a first control signal commanding to start a charging/discharging test for a first battery. The charging/discharging test device repeatedly performs a first charge/discharge cycle until a cumulative capacity of the first battery by the first charge/discharge cycle reaches a reference capacity in response to the first control signal. The first charge/discharge cycle is comprised of a first constant current charging until a first end-of-charge voltage is reached, a first rest period, a first constant current discharging until a first end-of-discharge voltage is reached and a second rest period in a sequential order, at a first temperature condition. Each time the first charge/discharge cycle is performed, the controller adds the cumulative capacity and a voltage drop of the first battery over the first rest period to a first test dataset.
