Battery balancing equalizes the state of charge (SOC) across all cells in a multi-cell battery pack. This technique maximizes the battery pack’s overall capacity and lifespan while ensuring safe operation.
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!
A battery balancer is a device or circuit designed to equalize the charge levels across multiple cells in a battery pack. It is a critical component of a battery management system (BMS) that ensures the battery pack’s optimal performance, safety, and longevity. A typical battery balancer consists of several key components:
However, they are prone to cell voltage imbalance over time, which can significantly reduce battery capacity and overall performance. To address this issue and improve the lifetime of battery packs, cell balancing methods have been developed.
According to battery levels, the balancing control methods are categorized as: cell–cell, cell-module and module-module balancing. Among these methods, cell–cell balancing is the most basic and efficient. However, cell–cell balancing is not suitable for battery packs integrated by thousands of cells. Cell-module balancing is realistic and common.
Efficiency of balancing control in full charge/full discharge condition is maximized (Kim et al. 2019). It is not necessary to apply balancing control on all conditions. In passive balancing, the remnant capacity is consumed by the resistances and transferred into heat. In this way, the inhomogeneities within the cell is improved.
