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 5):
The battery control device set forth in any one of  claim 1 , the battery control device being provided in a battery system comprising: the secondary battery; a power generator; an electric motor driven by a current of the secondary battery; and a battery cooling device driven by the current of the secondary battery, the battery control device being used to control the current of the secondary battery, the battery control device comprising:\n a first determination unit that determines, on the basis of the first correlations, whether or not a requested current for the secondary battery is lower than or equal to the upper limit current; and a second determination unit that determines, on the basis of the second correlations, whether or not a requested current for the secondary battery is higher than or equal to the lower limit current, wherein: when it is determined by the first determination unit that the requested current is higher than the upper limit current, the battery control device causes the secondary battery to output the upper limit current, and causes the power generator to supply the electric motor with a current equivalent to a difference between the requested current and the upper limit current; and when it is determined by the second determination unit that the requested current is lower than the lower limit current, the battery control device causes the secondary battery to output the requested current, and causes a current input into the battery cooling device from the secondary battery to decrease.
