4. Product working curve and performance
4.1CC/CV charging mode for lithium battery
The pre charging process is only started when the battery pack voltage is lower than U2 (the charger will not start when the battery pack voltage is lower than U1). The constant current charging is conducted with I1, and the pre charging process is ended when the voltage rises to U2
(2)Constant current charging:
Carry out constant current charging with I2, and end the constant current charging process when the voltage rises to U3
(3)Constant voltage charging:
Charge at constant voltage with U3, and end the whole charging process when the current drops to I3
