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.
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.
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.
Building a LiFePO4 battery pack involves several key steps. It is to ensure safety, efficiency, and reliability. Start by gathering LiFePO4 cells, a Battery Management System (BMS). Also, a suitable enclosure, and welding equipment. Arrange the cells in a series or parallel configuration. Consider the desired voltage and capacity before arranging.
In LiFePO4 batteries, as soon as the cell with the lowest voltage hits the discharge voltage cut off designated by the BMS or PCM, it will shut down the entire battery. If the cells were unbalanced during discharge, this may mean that some cells have unused energy and that the battery isn’t truly “empty”.
And secondary reactions within a lithium-ion battery, including LFP, use active material within the battery, which is unrecoverable and poses safety risks. Because lithium-ion batteries incorporate a BMS which protects the cells from unsafe voltage, current and temperature, the battery will not enter these conditions.
