Several common methods of battery charging
1. Ni-Cd and Ni-MH battery charging:
a. constant current charging: the charge current is in a certain valueone in the whole process of charging , this method is the most common.
b. constant voltage charge: both ends of charging power maintains a constant value in the process of charging, the circuit current gradually decreases as the battery voltage increases.
c. constant current constant voltage charging: constant current charging the battery to CC for the irst time, when the battery voltage rises to a certain value, the voltage remains CV, the circuit current is reduced to a small, tends to 0.
2. Lithium battery charging: constant current constant voltage charging: constant current charging the battery to CC for the first time, when the battery voltage rises to a certain value, the voltage remains the same CV, the circuit current is reduced to a small, tends to 0
