However, like any battery, LiFePO4 cells need to be balanced to ensure optimal performance and longevity. Balancing is the process of equalizing the voltage and state of charge (SOC) of each cell in a battery pack. This prevents overcharging or undercharging of individual cells, which can cause damage, reduce capacity, and shorten lifespan.
Additionally, continuously charging and discharging an imbalanced battery will exacerbate this over time. The relatively linear discharge profile of LiFePO4 cells makes it increasingly important that all cells are matched and balanced – the greater the difference between the cell voltages, the lower the obtainable capacity.
LiFePO4 battery packs ( or any lithium battery packs) have a circuit board with either a balance circuit, protective circuit module (PCM), or battery management circuit (BMS) board that monitor the battery and its cells (read this blog for more information about smart lithium circuit protection).
The theory is that balanced cells all discharge at the same rate, and therefore cut-off at the same voltage every time. This isn’t always true, so having a balancing circuit (or PCM/BMS) ensures that upon charging, the battery cells can be fully balanced to maintain the battery’s design capacity and to become fully charged.
With the development of various lithium-ion battery chemistries such as lithium iron phosphate (LFP), there is no longer available material in the batteries to be used up, replenished, recombined, etc.
There are no two identical leaves in the world, and the same applies to LiFePO4 battery cells. There are slight differences in capacity, voltage, internal resistance and self-discharge rate between LiFePO4 cells produced from the same batch. And this difference will be amplified as the battery is used for a longer period of time.
