  "textContent": "In a battery model identification method of the present invention, an M-sequence input electric current production part 2 inputs M-sequence signals with different frequency components as an electric current input into the battery 4. In this occasion, terminal voltage of the battery is measured by a voltage sensor 5, and a parameter estimation part 3 executes system identification based on the measured result to calculate frequency characteristics of the battery. Resistance components Rb, R1-R3 and capacitance components C1-C3 as parameters of a battery model 7 are identified based on the calculated frequency characteristics.",
