In active battery balancing, a charging current is intentionally routed between a high SOC cell and a lower SOC cell. This is done with an interconnection as in the passive case, but the charge is intentionally directed between specific cells rather than allowing the charge to balance naturally.
In addition, getting the battery pack back into balance can take days or weeks of balancing downtime, during which the pack is out of commission. Also, battery packs that are regularly cycled while out of balance will degrade faster than packs that are kept balanced.
The time taken to equalise the battery bank depends on the voltage difference between the batteries. As the equaliser works on the principle of equalisation, battery equalization time can vary from days to weeks, but normally the equalisation can be completed automatically in 2 days.
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.
The theory is that balanced cells all discharge at the same rate, and therefore cut-off at the same voltage every time. This isn’t always true, so having a balancing circuit (or PCM/BMS) ensures that upon charging, the battery cells can be fully balanced to maintain the battery’s design capacity and to become fully charged.
Imbalanced cells lock away otherwise usable energy and increase battery degradation. Batteries that are out of balance cannot be fully charged or fully discharged, and the imbalance causes cells to wear and degrade at accelerated rates. This reduces both the revenue of every cycle and the lifespan of the battery.
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.

The individual cells in a battery pack naturally have somewhat different capacities, and so, over the course of charge and discharge cycles, may be at a different state of charge (SOC). Variations in capacity are due to manufacturing variances, assembly variances (e.g., cells from one production run mixed with others), cell aging, impurities, or environmental exposure (e.g., some cells may be subject to additional heat from nearby sources like motors, electronics, etc.), and c…
