Abstract
A secondary battery control unit has a calculating portion identifying a parameter of an equivalent circuit based on an estimation error that is obtained by a comparison between an actual output value of a secondary battery and an equivalent output value of the equivalent circuit. Based on a predetermined amount of an infinitesimal change in the parameter and an evaluation function that is obtained using a result of the comparison, the calculating portion numerically calculates a slope of the evaluation function and renews the parameter based on the slope. As a result, the secondary battery control unit has the calculating portion capable of identifying the parameter of the equivalent circuit while reflecting effects of deterioration of the secondary battery and capable of being integrated to a vehicle-mounted microcomputer.
