Free QuoteIf 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.
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.
Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. Cell balancing is all about the dissipation or movement of energy between cells, so the SoC of all are aligned.
You can also place a li-ion balancer in your pack to perform active cell balancing, increasing the lifetime of your battery pack. When you wire an active balancer in your pack, you want to make sure that the balancer matches the series groups that you have in your pack.
After performing cell balancing, each cell's SoC reaches 60 % (average SoC) which signifies that all cells have reached to same level or balanced. Therefore, SoC balancing is crucial in EV battery pack to increase the usable capacity. Fig. 3. Charge among five cells connected in series before and after SoC balancing.
