    Abstract: Through the present invention, a residual capacity is measured with good precision even when a system for calculating the residual capacity of a storage cell on the basis of voltage and a system for calculating the residual capacity of a storage cell according to current integration are combined. In the present invention, as a first differential residual capacity, a difference value is calculated between a first residual capacity indicating the residual capacity of a storage cell at a first time, calculated by a voltage estimation system from the voltage and current of the storage cell at the first time, and the residual capacity of the storage cell at a second time, calculated by a voltage estimation system from the voltage and current from the storage cell at the second time. A second differential residual capacity is then calculated indicating the difference value between the residual capacity of the storage cell at the first time and the residual capacity of the storage cell at the second time, by a current integration system, on the basis of the integrated amount of current in the period between the first time and the second time. A current increase/decrease range indicating the increase/decrease of the current from the current at the first time and the current at the second time is then calculated, the first differential residual capacity or the second differential residual capacity is switched as the differential residual capacity on the basis of the current increase/decrease range, and the sum of the first residual capacity and the switched differential residual capacity is outputted as the residual capacity of the storage cell at the second time.
