DYNAMIC MODELING AND SIMULATION OF BATTERY MANAGEMENT SYSTEM AND BATTERY

Abstract

The increasing adoption of electric vehicles (EVs) requires reliable and efficient battery systems capable of delivering high performance under varying operating conditions. A Battery Management System (BMS) plays a crucial role in monitoring, controlling, and protecting rechargeable battery packs. This project presents the dynamic modeling and simulation of a lithium-ion battery and its associated Battery Management System using MATLAB/Simulink. The developed model includes battery electrical characteristics, State of Charge (SOC) estimation, voltage and current monitoring, temperature monitoring, cell balancing, and protection functions. The battery model is evaluated under different charge and discharge conditions to investigate terminal voltage, current, SOC, and power characteristics. Simulation results demonstrate that the proposed BMS effectively maintains the battery within safe operating limits and accurately tracks the SOC. The developed model provides a useful platform for analyzing battery performance and developing advanced BMS control strategies for electric-vehicle applications.
