    摘要： The present invention provides a control device of a secondary battery. The control device of the secondary battery using, as a positive electrode material, a positive electrode active material that shows a difference of an open circuit voltage curve between during charge and discharge, has a judging unit that judges, on the basis of a charge-discharge state of the secondary battery, whether or not calculation of a current SOC of the secondary battery is possible; and a charge controlling unit that, when judged that the calculation of the current SOC of the secondary battery is not possible by the judging unit, charges the secondary battery up to a predetermined fully charged state.

    摘要： A control device of a secondary battery using, as positive electrode material, positive electrode active material showing a difference of an open circuit voltage curve between during charge and discharge, detects whether the secondary battery is in a charge state or a discharge state. When the secondary battery is in the charge state, the control device calculates, as a current SOC, a value that is lower than an SOC corresponding to a current open circuit voltage of the secondary battery on a reference SOC-open circuit voltage curve showing a relationship between the SOC and the open circuit voltage, which becomes a reference upon calculating the current SOC. When the secondary battery is in the discharge state, the control device calculates as the current SOC, a value that is higher than the SOC corresponding to the current open circuit voltage of the secondary battery on the reference SOC-open circuit voltage curve.
