Here are the most popular formulas used to calculate this: Charge Time = Battery Capacity (Ah) / Charging Current (A) This formula is a straightforward way to estimate charge time. For instance, if you have a battery capacity of 50 Ah and a charger that provides 10A, the battery would theoretically take 5 hours to charge.
The C-rate of a lithium battery shows how quickly it can charge or discharge compared to its capacity. To calculate it, divide the charge/discharge current by the battery’s capacity. For instance, a 2000mAh lithium battery discharging at 1A is 1C. Factors like battery chemistry and size affect C ratings.
Formula: Battery charge and discharge rate in amps = Battery capacity (Ah) × C-rate let's say you have a 100ah lead-acid battery. 100Ah lead-acid battery has a recommended charge and discharge rate of 5 amps let's say you have a 100ah lithium battery. 100Ah lithium-ion battery has a recommended charge and discharge rate of 50 amps
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).
LiIon's are charged at CC = constant current = <= max allowed current from 'empty' until charge voltage reaches 4.2V. They are then charged at CV = constant voltage = 4.2V and the current falls under battery chemistry control. Charge endpoint is reached when I_charge in CV mode falls to some preset % of Imax - typically 25% to 50%.
Formula: C-rate in time (hours) = 1 ÷ C-rate Formula: C-rate in time (minutes) = (1 ÷ C-rate) × 60 The chemistry of battery will determine the battery charge and discharge rate. For example, normally lead-acid batteries are designed to be charged and discharged in 20 hours.
