Consequently, the authors review the passive and active cell balancing method based on voltage and SoC as a balancing criterion to determine which technique can be used to reduce the inconsistencies among cells in the battery pack to enhance the usable capacity thus driving range of the EVs.
Battery cell balancing fundamentals Battery cell balancing is an important process in BMS, playing a pivotal role in various applications such as EVs, renewable energy storage, and portable electronics. Its primary objective is to ensure that all individual cells within a battery pack maintain the equal SoC or voltage.
One of the most important parameters of estimation the performance of battery cell balancing is the equalization time. Other parameters such as power efficiency and loss are related to the balancing speed.
This study presented a simple battery balancing scheme in which each cell requires only one switch and one inductor winding. Increase the overall reliability and safety of the individual cells. 6.1. Comparison of various cell balancing techniques based on criteria such as cost-effectiveness, scalability, and performance enhancement
These balancing methods are typically integrated into a BMS, which continuously monitors and manages the state/voltage of each cell, contributing to enhanced battery pack performance, safety, and overall longevity by adding an additional balancing circuit with the battery pack. The overview of cell balancing is shown in Fig. 9.

Battery Cell Imbalance: What it Means (+How to Balance Batteries…
Battery balancing. The solution is battery balancing, or moving energy between cells to level them at the same SoC. In the above example, balancing would raise the cell at 90% SoC to match the other cells at 100% SoC. Thus, the previously locked-away energy is recovered, returning the pack to its nameplate capacity.
