A Study on the Comparison of Simple Model and Zero-Hysteresis Model about Lithium-Ion Cell Simulation

This study attempted to simulate the current-voltage characteristics using “Simple Model” and “Zero-Hysteresis Model” among the techniques to model the behavior of the battery cells and evaluate their usefulness through comparison with the experimental values. To this end, a battery charging and discharging system was implemented to show information on the current-voltage of the cell during the charging and discharging process and compared with the modeling results. As a result, both models showed results that generally match the experimental values in the actual application range despite the high difficulty of modeling, so it was confirmed that they are modeling tools that can be used in BMS (Battery Management System) design.
