Because of their multiple advantages, lithium-ion batteries are widely employed in a variety of applications ranging from wireless headphones to electric cars. They do, however, have disadvantages such as thermal issues, cell voltage imbalance, and safety concerns. The cell voltage in a battery pack must be balanced in order to determine its overall capacity and lifespan. A battery pack of four 3.7 V/1200 mAh lithium-ion batteries is researched under fixed temperature settings in this paper, with the goal of balancing cell voltages during charging and discharging via passive cell balancing. A battery management system (BMS) is used to monitor changes in cell temperatures, voltage, and current to ensure the lithium-ion battery’s health. The simulation environment was created with MATLAB, and simulation results for various temperatures are provided. The proposed method was tested utilizing a cloud-based battery parameter monitoring system, and the cell-balancing analysis is reported as a result. Overall, this work presents a practical approach for managing and balancing lithium-ion battery cell voltages in order to ensure safe and consistent battery performance.
