6 FAQs about [What to do if the lithium battery pack is unbalanced]

How to balance a battery pack correctly?

needs two key things to balance a battery pack correctly: balancing circuitry and balancing algorithms. While a few methods exist to implement balancing circuitry, they all rely on balancing algorithms to know which cells to balance and when. So far, we have been assuming that the BMS knows the SoC and the amount of energy in each series cell.

What does unbalanced battery pack mean?

This unbalanced pack means that every cycle delivers 10% less than the nameplate capacity, locking away the capacity you paid for and increasing degradation on every cell. The solution is battery balancing, or moving energy between cells to level them at the same SoC.

What happens if a battery pack is out of balance?

A battery pack is out of balance when any property or state of those cells differs. Imbalanced cells lock away otherwise usable energy and increase battery degradation. Batteries that are out of balance cannot be fully charged or fully discharged, and the imbalance causes cells to wear and degrade at accelerated rates.

How long does it take to get a battery pack back in balance?

In addition, getting the battery pack back into balance can take days or weeks of balancing downtime, during which the pack is out of commission. Also, battery packs that are regularly cycled while out of balance will degrade faster than packs that are kept balanced.

How does a battery management system work?

Thus, the previously locked-away energy is recovered, returning the pack to its nameplate capacity. A Battery Management System (BMS) is a piece of hardware that measures the voltage, current, and temperature of each cell in the battery system. The BMS performs basic safety functions to keep battery cells within rated operating conditions.

Do out-of-balance batteries cost you money?

Out-of-balance batteries cost you money in the short and long term. When an out-of-balance battery is charged or discharged, it delivers less than the nameplate capacity, leaving revenue on the table in every cycle.
