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.
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.
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.
The Li-ion battery pack is made up of cells that are connected in series and parallel to meet the voltage and power requirements of the EV system. Due to manufacturing irregularity and different operating conditions, each serially connected cell in the battery pack may get unequal voltage or state of charge (SoC).
With the advancement of EV technologies, lithium-ion (Li-ion) battery technology has emerged as the most prominent electro-chemical battery in terms of high specific energy and specific power. The Li-ion battery pack is made up of cells that are connected in series and parallel to meet the voltage and power requirements of the EV system.
