Abstract
In the battery deterioration prediction system, a polarization calculation unit calculates negative and positive electrode polarizations from negative and positive electrode resistances, and an electrical current value flowing through the secondary battery. A CCP calculation unit calculates a negative electrode closed-circuit potential on the secondary battery negative electrode open circuit potential and the negative electrode polarization calculated by the polarization calculation unit, and calculates a positive electrode closed-circuit potential based on the secondary battery positive electrode open circuit potential and the positive electrode polarization calculated by the polarization calculation unit. A capacity prediction unit predicts the positive/negative electrode capacity, and positive/negative electrode SOC deviation capacity of a secondary battery based on at least one of the closed-circuit potential of the negative and positive electrodes calculated by the CCP calculation unit, and predicts the battery capacity based on the negative and positive electrode capacities, and the positive/negative electrode SOC capacity deviation.
