PROBLEM TO BE SOLVED: To provide a method of calculating a storage state quantity of a secondary battery capable of accurately extracting the storage state quantity by a neural network operation, while preventing detection accuracy from dropping due to variations in the characteristics of a target to be measured, while increasing detection opportunities. SOLUTION: The method of calculating the storage quantity of the secondary battery calculates the storage state quantity of the secondary battery by means of a neutral net, while using a deduced coefficient value of a mathematical model, deduced by means of battery state data detected from the secondary battery, the mathematical model of the secondary battery, and the battery state data as input parameters. The input parameters to be employed in the neutral net operation include a polarization-related quantity which is an electrical quantity, related to charging and discharging current in a predetermined period, immediately before polarization quantity of the secondary battery is influenced, the voltage and current of the secondary battery, and in addition, coefficients R, L and C calculated by a mathematical model corresponding to an RLC serial connection circuit model of the secondary battery.
