When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
Required Charging Current for battery = Battery Ah x 10% A = Ah x 10% Where, T = Time in hrs. Example: Calculate the suitable charging current in Amps and the needed charging time in hrs for a 12V, 120Ah battery. Solution: Battery Charging Current: First of all, we will calculate charging current for 120 Ah battery.
Charging Time of Battery = Battery Ah ÷ Charging Current T = Ah ÷ A and Required Charging Current for battery = Battery Ah x 10% A = Ah x 10% Where, T = Time in hrs. Example: Calculate the suitable charging current in Amps and the needed charging time in hrs for a 12V, 120Ah battery. Solution: Battery Charging 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. In other words, you can have "any time" as long as when you multiply it by the current, you get 100 (the battery capacity).
About 65% of the total charge is delivered to the battery during the current limit phase of charging. Assuming a 1c charging current, it follows that this portion of the charge cycle will take a maximum time of about 40 minutes. The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V.
There are two main methods of charging a battery: Constant current method. In this charging method the batteries are charged at a constant current. The charging current is set by introducing some resistance in the Circuit. This method has its own drawbacks because the state of charge Of the battery is not taken into account.
For a more accurate estimation, you can assume 80% efficiency for NiCd and NiMh batteries and 90% efficiency for LiIon/LiPo batteries. Then, the formula becomes capacity / (efficiency * chargeRate) or, to use the same values from above (assuming lithium chemistry), 100Ah / (0.9 * 10A) = 11.11 hours Discharge rates are well enough covered here.
