A base resistance of the battery is obtained by cyclically measuring a discharge current and a voltage between a pair of terminals of the battery, while a rush current is flowing in an electric load electrically connected to the pair of the terminals. The rush current monotonically decreases from a peak to a constant value after the rush current monotonically increases from zero to the peak. A concentration polarization resistance and an activation polarization resistance of the battery are also obtained from the discharge current and the terminal voltage. A degradation degree of the battery is obtained by multiplying the degradation degrees of the base resistance and the polarization resistances together.
