What are the common charging methods?

Lithium battery charging method:

Constant current and constant voltage charging: The battery is first charged with constant current (CC), when the battery voltage rises to a certain value, the voltage remains unchanged (CV), and the current in the circuit drops to a very small value, and eventually tends to 0.
