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 3):
The battery control device according to  claim 2 , further comprising a battery resistance increase rate calculation unit that calculates a battery resistance increase rate at the time of a decrease in capacitance of the secondary battery on the basis of the first data indicating the resistance increase rate of the positive electrode of the secondary battery, and the second data indicating the resistance increase rate of the negative electrode of the secondary battery, and on the basis of the battery state-of-charge, the positive electrode state-of-charge and the negative electrode state-of-charge calculated by the state-of-charge calculation unit,\n wherein the correlation calculation unit calculates the first correlations and the second correlations on the basis of the allowable range, and the battery resistance increase rate at the time of the decrease in capacitance.
