Abstract
Abstract The internal battery resistance can be measured using any one of the three available methods; conductance, impedance, or resistance measurements. An experimentally validated modeling technique using COMSOL multiphysics software has been developed to explain the importance of electrochemical impedance spectroscopy (EIS) modeling. The influence of the design parameters on the cell impedance in a wide frequency range has been investigated. Some of the defined properties studied in this work may have a significant role in the design of battery management system (BMS) for EVs and HEVs. The verification results have shown the dependency of the impedance calculation on active material particle radius and the current rate, especially at the positive electrode.
