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:
When a battery is fully charged, the charging current drops to 0.1C. The circuit switches to constant voltage charging mode once the voltage achieves its maximum, charge cut-off voltage. The charging current of the battery steadily lowers down, and the charging rate slows down when the voltage is sustained at charge cut-off voltage.
Several factors, including the battery capacity and charging rate, affect the battery charging current. The larger the battery capacity, the higher the charge current typically is. Likewise, the higher the charging ratio, the higher the charging current and the shorter the charging time.
Generally, the charging current for a 12V battery is around 10% of the battery’s capacity. Charging current can vary based on battery type; lead-acid batteries are generally charged at a rate of 10% of their capacity, while lithium-ion batteries can handle higher charging currents, sometimes up to 100% of their capacity.
As the battery reaches 85% of its capacity, the charging current is increased significantly. After the target voltage level is achieved, the charging current decreases and the battery gradually gets charged up to 100%.
The maximum charging current for a 100 Ah, 12V lithium battery is around 20 Amps as a general rule.
