Here''s a general voltage vs. state of charge (SoC) relationship for a typical lithium iron phosphate (LiFePO4) battery used in a 12V system: Charge Phase: 100% SoC corresponds to a fully charged battery, and the voltage typically ranges from around 13.8V to 14.6V. As the battery discharges, the SoC decreases, and the voltage gradually drops.
The battery value chain looks at the whole eco system from mining the raw materials through to recycling. The value is perhaps normally thought of simply in terms of financial returns, but this eco system needs to look at many factors:
Battery terminology (Ah, specific gravity, voltaic cell etc.). Different battery designs and types (lead-acid, nickel-cadmium, mercury etc.). Battery hazards (shorting, gas generation etc.). Battery operations (series, parallel, primary, secondary etc.). And a lot more! The course is packed with images, animations and high-quality written content.
In any battery pack design it is only as strong as the weakest link [4], one bad cell or group of cells in the series string will control the total power and energy available from the pack. This means it is important to match the cells and to keep them balanced throughout the lifetime use of the pack. ... 1 thought on "Cell Balance and End of ...
