Why Balancing Cells in a LiFePO4 Battery Is Critical (And How to Do It Right!) LiFePO4 batteries, or lithium iron phosphate batteries, are known for their reliability and safety. They are widely used in electric vehicles, solar power systems, and energy storage solutions. A key...
Working principle That equalization system is able to adjust each cell to be equal can avoid the phenomenon which in-pack cell overcharge or over-discharge occurring. For lithium iron phosphate battery series, data acquisition module collects the real-time data of in-pack cells involved terminal voltage, working current and temperature.
Bottom Balancing requires discharging all cells to a minimum safe voltage before assembling them. This approach is better suited for optimizing the discharge process, ensuring that all cells deplete their charge evenly. Choosing between top and bottom balancing depends on how you intend to use your LiFePO4 battery pack.
A battery-equalization scheme is proposed to improve the inconsistency of series-connected lithium iron phosphate batteries. Considering battery characteristics, the segmented hybrid control strategy based on cell voltage and state of charge (SOC) is proposed in this paper.
Lithium iron phosphate battery voltage change dramatically in the end of the charge and discharge, it means that voltage difference is obvious between in- pack cells even if the battery SOC were similar, the voltage-based equalization algorithm is more advantageous to improve the inconsistency of the battery pack at this stage.
In a battery with a balancing circuit, the circuit simply balances the voltages of the individual cells in the battery with hardware when the battery approaches 100% SOC – the industry standard for lithium iron phosphate is to balance above a cell voltage of 3.6-volts.
