AI Customer ServiceHere is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
Charging properly a lithium-ion battery requires 2 steps: Constant Current (CC) followed by Constant Voltage (CV) charging. A CC charge is first applied to bring the voltage up to the end-of-charge voltage level. You might even decide to reduce the target voltage to preserve the electrode.
By Irena Zhuravchak and Volodymyr Ilchuk | Tuesday, June 27, 2023 Charging a battery using the constant-current/constant-voltage (CC/CV) method involves using the constant current in the initial state of charging and then switching to constant voltage in the later stages of charging, when the battery reaches the set charge level.
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.
In Constant Current State, the battery is charged by a constant current keeping the voltage equal to the peak terminal voltage of the battery. The constant current required for charging the battery is decided by its C. Generally, the batteries are charged by a rate 0.5C to 0.8C in this charging mode. The battery charges very fast in this state.
When the terminal voltage of the battery reaches to 4.2V then the battery needs to be charged with a Constant Voltage Source. Now the CC state should be cut off and the charging current should start decreasing. The constant voltage should be equal to the maximum voltage of the battery to fully charge it.
