This study investigates the challenge of cell balancing in battery management systems (BMS) for lithium-ion batteries. Effective cell balancing is crucial for maximizing the usable capacity and lifespan of battery packs, which is essential for the widespread adoption of electric vehicles and the reduction of greenhouse gas emissions.
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.
Balancing attempts to ensure that all cells reach their full capacity simultaneously, maximizing the usable capacity of the battery. Overcharging or deep discharging even a single cell can significantly harm the cell.
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.
Individual cell voltage stress has been reduced. This study presented a simple battery balancing scheme in which each cell requires only one switch and one inductor winding. Increase the overall reliability and safety of the individual cells. 6.1.
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.
