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 lithium-ion battery pack is composed of multiple single lithium-ion batteries connected in series. Due to the differences in the cells, when the terminal voltage rises inconsistently when charging in series, some cells will be overcharged and some cells will be undercharged.
Therefore, 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.
When a group of lithium-ion batteries is charged in series, each battery should be charged in a balanced manner, otherwise, the performance and life of the whole group of batteries will be affected during use. 1. Add a parallel equalization circuit to every single battery of the lithium-ion battery pack to achieve the purpose of shunting.
Lithium battery pack 48V20AH generally single lithium battery is 3.5V, so 48V lithium battery pack needs 48/3.5=13.7, just take 14 in series. If the manufacturer has provided a set of 12V lithium batteries, then 4 can be connected in series. As long as the output voltage is 48V, the current is 2A or 4A.
The method undergoes a real-world electric vehicle testing with 276 cells. The limited charging performance of lithium-ion battery (LIB) packs has hindered the widespread adoption of electric vehicles (EVs), due to the complex arrangement of numerous cells in parallel or series within the packs.
