Provided is a battery control device capable of controlling the deterioration speed of the characteristics of a secondary battery on the basis of the internal resistances of the positive electrode and the negative electrode of the secondary battery. The battery control device 138 comprises: a storage unit 1381 for holding beforehand a data table DT2 indicating the rate of increase in the resistance of the positive electrode in the secondary battery and a data table DT2 representing the rate of increase in the resistance of the negative electrode in the secondary battery; and a DT1 calculation unit 1382 calculating a data table DT1 representing the correlations among the temperature, the battery state-of-charge and the upper limit current of the secondary battery, and the correlations among the temperature, the battery state-of-charge and the lower limit current of the secondary battery on the basis of the data table DT2, a positive electrode state-of-charge, a negative electrode state-of-charge, a battery state-of-charge, and an allowed range for the rate of increase in the battery resistance of the secondary battery. The battery control device 138 controls the current of the secondary battery on the basis of the data table DT1 calculated by the DT1 calculation unit 1382. |
