Typically, you charge lithium batteries by applying the CC-CV scheme. CC-CV stands for Constant Current - Constant Voltage. It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts.
Typically, PMICs charge LiPo and Lithium-Ion batteries using the CC-CV method. The battery gets charged with a constant current until the cell reaches its maximum voltage. From then on, the charger gradually decreases the charge current until the battery is fully charged. Modern charge ICs apply a few more steps to the process to increase safety.
When designing a single-cell Lithium-Ion charger, record the allowed maximum charge current and voltage of the battery in use. Then determine the voltage and maximum charge current of the power supply you want to use for charging. Usually, this will be five volts and between 500 mA and 900 mA (USB 2.0 and USB 3.0).
The charging method for a lithium battery is limited voltage and constant current, which is controlled by an IC chip.
This third part of the series introduces how to correctly charge Lithium-Ion and LiPo batteries so that you can understand what you need to do when implementing a custom charging circuit. Typically, you charge lithium batteries by applying the CC-CV scheme. CC-CV stands for Constant Current - Constant Voltage.
The voltage for constant current charging of a lithium ion battery is between 3.0-4.2V*. The current for constant current charging is between 0.2C and 1.0C. When the battery voltage rises to 4.2V, the constant current charging ends and the constant voltage charging phase begins.*
