What is a passive cell balancing system for lithium-ion battery packs?

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.

Regularly check the battery pack’s health. Recharge and rebalance as needed. Balancing cells in a LiFePO4 battery is essential for longevity, efficiency, and safety. Whether you use a BMS, active or passive balancing, or manual methods, maintaining balanced cells ensures optimal performance.

Does a lithium ion battery have a balance problem?

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.

What happens if battery cells are not balanced?

Battery cells in series have no way of transferring energy between one another. So if your cell groups are not perfectly balanced, the BMS will cut your battery off long before your battery pack is actually out of energy. What Is Lithium-Ion Cell Balancing? Cell balancing is the act of making sure all cells in a battery are at the same voltage.
