The charging curve for lithium-ion batteries typically follows the CC-CV (Constant Current - Constant Voltage) scheme1. Here are the key points:Constant Current (CC) phase: The maximum allowed charging current is applied to the battery until the cell voltage reaches its maximum value (e.g., 4.2 Volts).Constant Voltage (CV) phase: After reaching the maximum voltage, the charging current gradually decreases while maintaining a constant voltage.During the charging process, the voltage gradually increases, and the current gradually decreases2.
