To calculate the charging time of a 2000MAH lithium battery with a charging current of 1000MA, use the 0.5C calculation formula: charging time t = battery power (c) / charging current (i). So, the theoretical charging time would be 2000MAH / 1000MA = 2 hours. However, in practice, the charging time is longer than the theoretical time due to energy loss during charging.
Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm. Observing the below picture, it becomes evident that the DC power source regulates its charging voltage in accordance with the charging current limit.
Constant current charging refers to a charging method where the current is always constant and the voltage slowly rises to the set value (the upper limit voltage of the ternary lithium battery is 4.2V). The current for constant current charging is between 0.5C and 1.0C.
If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour. In other words, you can have "any time" as long as when you multiply it by the current, you get 100 (the battery capacity).
In the ideal/theoretical case, the time would be t = capacity/current. If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour.

Battery charging time at constant current. The formula for calculating the charging current is: I = Q * k, where Q is the battery capacity, and k is a certain ratio of the nominal (its ideal value is within 0.04… 0.06, and the optimal value is 0.1). Proceeding from such a recommendation, the calculation of the time that is needed for a fully loaded battery has the following form: T = Q / I ...
