Lithium-ion battery tissues not only show different behaviors depending on destruction and charging states, but additionally overcharge and overdischarge of cells shorten battery lifetime and cause safety issues, thus studies aiming to provide an accurate condition of a cell are needed. Measurements of battery cell impedance are used designed for cell SoH and SoC estimation techniques, but it generally takes a long time for the purpose of a cell in each state to be prepared and cell voltage response is measured when getting and discharging under each condition. This study introduces the equivalent circuit model of lithium-ion cells formulated in the MATLAB/Simulink atmosphere. Cell SoC, SoH, heat range, and C-rate are viewed as for more accurate cell impedance prediction, and the simulation answers are verified with the measurement results. The created model would work for make use of in cell SoC plus SoH monitoring studies by successfully outputting cell impedance through real-time prediction of cell voltage during release.
