Development of a Simple Battery Management System for Cell Balancing

Abstract

As the use of Lithium Ion (Li-Ion) battery is increasing, proper means of increasing the life cycle and reliability of the battery should be adopted. A discussion on the precautions to be carried out while integrating Li-Ion batteries are discussed. A Battery Management System (BMS) is developed to address the unbalance State of Charge (SoC) issue that arise in the battery pack. The proposed algorithm is simulated in MATLAB Simulink. The battery pack used in this simulation is inspired from Tesla. This paper can be used as a tutorial or as a reference for anyone getting started with Li-Ion batteries or battery management systems.
