Introduction to the charging methods of Ni-MH batteries and Li-ion batteries

Ni-MH battery charging method: 01) Constant current charging: The charging current is a certain value during the entire charging process, this method is the most common; 02) Constant voltage charging: Both ends of the charging power supply maintain a constant value during the charging process, in the circuit The current gradually decreases with the increase of battery voltage; 03) 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 circuit The current drops to a small amount and eventually tends to zero. Li-ion 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 the same (CV), the current in the circuit drops to a small amount, and finally Tend to 0.
