One of the main factors that determine the performance of a battery pack is the performance of the BMS(Battery Management System), which can be implemented by design algorithms according to battery modeling optimization and accurate voltage, current, and temperature measurements. Since battery packs are exposed to various physical environments in mobility applications such as electric vehicles, drones, and robots, battery modeling reflecting this can be said to be essential to implement high-performance BMS. This study attempted to simulate the current-voltage characteristics of the battery using the “Simple Model” method and evaluate its usefulness. To this end, a pulse-controlled battery charging and discharging system was implemented to display information on the transient phenomenon of cell voltage change during the charging and discharging process, and this was compared with the modeling results. As a result, the applied Simple Model has many parameters and variables to be considered when modeling, so it was confirmed that it is a useful evaluation tool for BMS design because it showed the results consistent with the actual cell voltage change despite the high difficulty of modeling.
