HOME / Lithium battery pack parallel charging solution - RADIO-ENERGY
I''m looking to build a battery pack from lithium-ion 18650 cells, 13s16p (parallel first) to achieve around a 50V (nominal) battery pack. I realize there are probably charge solutions out there with the proper voltage and BMS which can be used to charge the entire pack with balancing and protection; however, my idea is to use a single adjustable buck CC power

Traction batteries contain a high number of parallel-and serial-connected lithium-ion cells to satisfy power and energy requirements of electric vehicles .
The conventional solution can use this model to switch the constant current charging into the constant voltage charging with the correct timing to avoid overcurrent charging. Other battery pack protection methods including current sense resistor, resettable thermal cutoff device, or resettable fuse can also use this mathematical model to
Subsequently, the intelligent charging method benefits both non-feedback-based and feedback-based charging schemes. It is suitable to charge the battery pack considering

Someone mentioned that the 1A max current simply would not work for 9 parallel cells. Nonsense !!! it will work but it will take a very long time to charge. One cell of 2000 mAh (=2 Ah) (a typical 18650 is 2 - 2.5 Ah) takes 2
The controller discharges the battery pack until the current SOC of most-depleted cell (SOC min) reaches to 30%. Similarly, the controller charges the battery pack until the SOC max reaches greater than 99% (~100%). Two flags CH and DC are used to determine whether balancing need to be performed in charging period or in discharging period.
