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. A BMS needs two key things to balance a battery …
