The internal resistance and battery chemistry voltage sets the charging speed, when charging batteries usually you run current through the battery, then once it reaches a certain voltage you trickle charge it with the max voltage of the battery.
However, in the event of fast charging, which delivers a significant amount of current into the battery in a shorter time interval, the internal resistance of a battery increases. This increase in resistance and the high current input generates excessive heat inside the batteries, resulting in a high peak of temperature.
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases.

When the battery is almost fully charged the charge speed drops to prevent the battery cells from overheating. Typically at 80–90% SoC the speed drops and charging will slow down further closer to 100% SoC. That is the reason why fast charging is most effective between 0% and 80–90% SoC. Also, as mentioned before, the latest batteries are ...
