1. A simulation battery construction device comprising:
a processor configured to function as:
a first recognition element configured to recognize a measurement result of a complex impedance of a rechargeable battery;
a first calculation element configured to identify parameter values of a rechargeable battery model based on the measurement result of the complex impedance of the rechargeable battery recognized by the first recognition element, the rechargeable battery model expressing an impedance of an internal resistance of the rechargeable battery with transfer functions representing an IIR system and an FIR system, respectively;
a second recognition element configured to recognize a time series of a current command value;
a second calculation element configured to calculate a time series of voltage simulating the rechargeable battery as an output of the rechargeable battery model by inputting the time series of the current command value recognized by the second recognition element to the rechargeable battery model; and
a simulation battery control element configured to control an operation of a simulation battery connected to a designated apparatus so as to cause the time series of the voltage simulating the rechargeable battery calculated by the second calculation element to be applied to the designated apparatus.
