AI Customer ServiceIntroduction When using LiFePO4 batteries, balancing batteries in series is critical for ensuring maximum performance and lifetime. LiFePO4 batteries, recognized for their high energy density, extended lifetime, and
AI Customer ServiceTherefore, the lithium battery must also be about 58v, so it must be 14 strings to 58.8v, 14 times 4.2, and the iron-lithium full charge is about 3.4v, it must be four strings of 12v, 48v must be 16 strings, and so on, 60v There must be 20 strings in parallel with the same model and the same capacity.
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
The ternary lithium battery standard specifies a voltage of 3.7v, full of 4.2v, three strings are 12v, 48v requires four three strings, but the electric vehicle lead-acid battery is fully charged with 58v.
The whole set of batteries is 14 strings multiplied by 10 cells = 140 cells. Summary: Series and parallel have their own advantages for lithium iron phosphate batteries. Series and parallel lithium battery packs have different methods and achieve different goals.
Two 10ah batteries in parallel are 20ah, 48v ternary lithium must be 14+14 10ah batteries, and finally 14 parallel connected in series to form a 48v20ah lithium battery. Calculation method two: In fact, it is very simple. For example, 48 volts usually refers to voltage.
Since lithium cells must be managed on a cell level, parallel lithium strings dramatically increase the complexity and cost of the battery management and introduce many additional points of failure and failure modes not found with a single string.
