Passive and active cell balancing are two battery balancing methods used to address this issue based on the battery’s state of charge (SOC). To illustrate this, let’s take the example of a battery pack with four cells connected in series, namely Cell 1, Cell 2, Cell 3, and Cell 4.
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.
Individual cell voltage stress has been reduced. 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.
These methods can be broadly categorized into four types: passive cell balancing, active cell balancing using capacitors, Lossless Balancing, and Redox Shuttle. Each Cell Balancing Technique approaches cell voltage and state of charge (SOC) equalization differently. Dig into the types of Battery balancing methods and learn their comparison!
