  "textContent": "Provided is a device or the like that can improve the accuracy of battery performance evaluation of a rechargeable battery. Parameter values of a rechargeable battery model are identified on the basis of a measurement result of a complex impedance Z of a first rechargeable battery The rechargeable battery model expresses an impedance of an internal resistance of the first rechargeable battery with transfer functions representing IIR and FIR systems, respectively. Performance of a second rechargeable battery is evaluated on the basis of a result of contrast between a voltage response characteristic V(t) that is output from a rechargeable battery as the second rechargeable battery when an impulse current I(t) is input to the second rechargeable battery , and a model voltage response characteristic V(t) when the impulse current is input to the rechargeable battery model having the parameter values identified.",
