The presented research actually proposes a novel passive cell balancing system for lithium-ion battery packs. It is the process of ramping down the SOC of the cells to the lowest SOC of the cell, which is present in the group or pack. In simple words, consider a family having 5 members, such as parents and children's.
The BMS compares the voltage differences between cells to a predefined threshold voltage, if the voltage difference exceeds the predetermined threshold, it initiates cell balancing, cells with lower voltage within the battery pack are charged using energy from cells with higher voltage (Diao et al., 2018).
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.
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.
