6 FAQs about [How to deal with unbalanced battery pack]
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.
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.
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 is battery cell balancing?
Battery cell balancing brings an out-of-balance battery pack back into balance and actively works to keep it balanced. Cell balancing allows for all the energy in a battery pack to be used and reduces the wear and degradation on the battery pack, maximizing battery lifespan. How long does it take to balance cells?
Can battery balancing fix a dead or damaged cell?
Battery balancing cannot fix a completely dead or damaged cell. Balancing equalizes charge levels among functional cells. If a cell is severely degraded or has failed, you may need to replace it to restore the battery pack’s performance.
What is a battery pack?
A battery pack is a collection of battery cells packaged into an application-specific format. These can be as small as a single cell or as large as thousands of cells arranged in series and parallel configurations, along with any associated electronics and mechanical components. A battery cell is the smallest energy-storing unit of a battery.
