Battery balancing depends heavily on the Battery Management System. Every cell in the pack has its voltage (and hence SOC) monitored, and when imbalances are found, the pack's SOC is balanced. Passive balancing and active balancing are the two basic approaches to battery balancing.
An advanced method of managing an equal SOC across the battery pack’s cell is known as active battery balancing. Instead of dissipating the excess energy, the active balancing redistributes it, resulting in an increased efficiency and performance at the expense of elevated complexity and cost.
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.
A BMS (act as the interface between the battery and EV) plays an important role in improving battery performance and ensuring safe and reliable vehicle operation by adding an external balancing circuit to fully utilize the capacity of each cell in the battery pack. The overview of BMS is shown in Fig. 2. Fig. 2. Overview of BMS.
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.
