Simulation battery construction method and simulation battery construction device

摘要

Provided are an apparatus and the like capable of improving the reproducibility of a secondary battery under various conditions using a simulated battery. In each of the different degrees of deterioration D(n2), parameters P(n0, n1, n2) of the secondary battery model at different temperatures T(n1) are determined. Based on the measurement result of the complex impedance Z of the secondary battery 220, values of the parameters P(n0, n1, n2) of the secondary battery model are identified. In the secondary battery model, the impedance of the internal resistance of the secondary battery 220 is expressed by a transfer function representing each of the IIR system and the FIR system. Furthermore, when the current command value Icmd(t) is input to the secondary battery model according to the identifier id(m0), the temperature T(m1), and the deterioration degree D(m2) of the virtual secondary battery simulated by the simulated battery 20 A voltage command value Vcmd(t) is calculated, and the voltage V(t) is applied to the designated device 200 or its load by the simulated battery 20 .
