Free QuoteIf 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.
In lithium batteries, maintaining balance is crucial because it allows for the most efficient use of the battery's total capacity. It also prolongs the battery's lifespan by preventing overcharging or over-discharging of individual cells.
Balancing lithium batteries in parallel involves measuring each battery's voltage before connection, ensuring they're within an acceptable range of each other, and then connecting all positive and negative terminals together. What Does It Mean For Lithium Batteries To Be Balanced?
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.
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. This reduces both the revenue of every cycle and the lifespan of the battery.
Balancing lithium battery packs, like individual cells, involves ensuring that all batteries within a system maintain the same state of charge. This process is essential when multiple battery packs are used together in series or parallel configurations.
