You can see this in the blue line in the graph. In this simulation the internal battery voltage (Vint) had only reached 4.0 V when the charger switched to constant voltage mode at 4.2 V. By the time charging current dropped to 10% it had risen to 4.18 V, and as charging continued it eventually reached 4.20 V.
The current begins to drop as the battery starts to saturate; full charge is reached when the current decreases to 3–5 percent of the Ah rating. A battery with high leakage may never attain this low saturation current, and a plateau timer takes over to end the charge.
Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
Charging a lithium-ion battery involves precise control of both the charging voltage and charging current. Lithium-ion batteries have unique charging characteristics, unlike other types of batteries, such as cadmium nickel and nickel-metal hydride.
The lead-acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries.
Once the voltage level is reached, the battery seamlessly enters the next charging phase. Topping charge, which comprises most of the remaining charge time at a lowered charge current and is comparable to a dormant or relaxed state. This stage provides saturation.
