Contributed Commentary by Anton Beck, Battery Product Manager, Epec When a lithium battery pack is designed using multiple cells in series, it is very important to design the electronic features to continually balance the cell voltages. This is not only for the performance of the battery pack, but also for optimal life cycles.
If you built a lithium-ion battery and its capacity is not what you expect, then you more than likely have a balance issue. While it's true that cells connected in parallel will find their own natural balance, the same is not true for cells wired in series. Battery cells in series have no way of transferring energy between one another.
The meaning of battery balance is to keep the voltage of the lithium-ion battery cell or the voltage deviation of the battery pack within the expected range. So as to ensure that each battery cell remains in the same state during normal use, in order to avoid overcharging and over-discharging.
Therefore, balancing improves the Depth of Discharge (DOD), making the battery system more efficient. It's important to note that balancing only equalizes cell voltages to the average value of the pack and does not alter the inherent characteristics of the cells.
Whether you are new to battery building or a seasoned professional, it's totally normal to not know how to balance a lithium battery pack. Most of the time when building a battery, as long as you use a decent BMS, it will balance the pack for you over time. The problem is, this can take a very, very long time.
In Li-ion batteries which have very low self-discharge and therefore accumulative unbalance per cycle is usually less than 0.1%, bypass current of internal FETs is sufficient to keep the pack continuously balanced.
