Abstract:
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 and negative electrodes. The battery control device comprises: a storage unit for holding beforehand a data table DT 2  indicating the rate of increase in the resistance of the positive and negative electrodes; and a DT 1  calculation unit calculating a data table DT 1  representing the correlations among the temperature, the battery state-of-charge and the upper limit current, and the correlations among the temperature, the battery state-of-charge and the lower limit current on the basis of DT 2 , 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. The battery control device controls the current of the secondary battery on the basis of DT 1  calculated by the DT 1  calculation unit.

Claim (Index 4):
