The battery system includes a secondary battery, a voltage sensor, a current sensor, a temperature sensor, and a processor. The processor is configured to calculate a polarization overvoltage by subtracting a voltage drop amount caused by a DC resistance and a reactive resistance of the secondary battery determined in accordance with a temperature and an SOC of the secondary battery from a voltage difference between OCV and CCV of the secondary battery.
