Abstract
[Object] To detect states of a plurality of secondary batteries whose kinds are different with high accuracy. [Organization] A measurement unit (voltage sensor, current sensor) measuring a current value of a current flowing at a secondary batteryand a voltage value of a voltage generated at the secondary battery by the current in a predetermined frequency; an optimization unit (CPU) optimizing element constants of an equivalent circuit model of the secondary battery based on the measured voltage value and the current value; an identification unit (CPU) identifying a kind of the secondary battery with reference to the optimized element constants of the equivalent circuit model; a storage unit (ROM) storing detection formulas which detect the state of the secondary battery by each kind of the secondary battery; an acquisition unit (CPU) acquiring the detection formula corresponding to the identified kind from the storage unit; and a detection unit (CPU) detecting the state of the secondary battery by applying the element constants to the acquired detection formula, are included.
