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.
This is done with a sophisticated circuit that is able to connect to the higher voltage cell group, take the excess energy from it, connect to a lower voltage cell group, and then transfer the stored energy to them to bring them into balance.
