Modified Multi-inductor-Based Cell Balancing in Electric Vehicles

Cell balancing is an essential feature of battery management systems as the battery packs are affected by various factors, and imbalance is one of the major ones. Without balance, the cell's performance will drift apart, and much energy will be wasted in the battery pack when they are frequently operated in recycling conditions. Different methodologies for cell balancing have been proposed so far, which must be adequately applied considering the application of the battery pack. This paper presents a modified simple inductor-based active cell balancing technique in Electric Vehicles. The cell equalization topology has been simulated in MATLAB/Simulink. The performance is evaluated using the quantification of energy exchange. The results show that the proposed approach transfers energy in less time, with lower losses. Also, the design complexity is less.
