The charging current depends directly on the capacity of the battery, all other things being equal. When you read literature about batteries, you will come across C-rate. For example: "The battery was charged at 0.5C ." It's not temperature in Celsius, and it's not capacitance in Farads.
Importantly, the DC power source ensures that it does not exceed the maximum battery voltage limit during this adjustment. The relationship between the charging voltage and the battery charging current limit can be expressed by the formula: Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm.
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.
