DETERIORATION INHIBITION CONTROL SYSTEM, DETERIORATION INHIBITION CONTROL METHOD AND DETERIORATION INHIBITION CONTROL PROGRAM, AND RECORDING MEDIUM HAVING DETERIORATION INHIBITION CONTROL PROGRAM DESCRIBED THEREON
In a deterioration inhibition control system, a data obtainment unit obtains battery data including a voltage and an electric current of a secondary battery. A deterioration estimation unit estimates, based on the battery data of the secondary battery, a rate of decrease in an excess capacity of a positive electrode from an initial excess capacity to a current excess capacity of the positive electrode and a rate of decrease in an excess capacity of a negative electrode from an initial excess capacity to a current excess capacity of the negative electrode. When the rate of decrease in the excess capacity of the positive electrode is greater than the rate of decrease in the excess capacity of the negative electrode, a charging/discharging control unit switches charging/discharging control to charging/discharging control that prioritizes deterioration inhibition for the positive electrode, and when the rate of decrease in the excess capacity of the negative electrode is greater than the rate of decrease in the excess capacity of the positive electrode, the charging/discharging control unit switches the charging/discharging control to charging/discharging control that prioritizes deterioration inhibition for the negative electrode.
