1. Constant Current (CC) Stage During the initial phase of the charging cycle, the battery is charged at a constant current. The voltage gradually increases while the current remains constant until it reaches a predetermined threshold. This stage ensures that the battery charges quickly and efficiently. 2. Saturation Stage
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
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:
In the Completion Charge Phase, which is the latter part of the charging process, I maintain the voltage at a set point of 14.1 to 14.8 VDC and reduce the current until the battery reaches full charge.
Battery charging is simple in theory, but practical implementations that get maximum battery performance and lifetimes are much more complex and often require multi-stage charging. While constant current regulator designs can effectively charge NiMH and NiCd batteries, they are less than effective for charging Li and PbA batteries.
Charging Cycles A charging cycle is defined as one complete charge and discharge of a battery. Lithium-ion batteries have a limited number of charging cycles before their capacity starts to decline. It is important to note that a partial discharge followed by a recharge counts as a fraction of a full charging cycle.
