Lithium Dry Battery Charger  Five
The lithium battery charger introuduced in the example can charge 6V-plated ion battery in constant-current way and change into constant-voltage chagre mode when the battery reaches 4·1V. Work Principle of the Circuit This lithium battery charger circuit is composed of power supply constant voltage circuit,oscillator,voltage detection control circuit,constant-current charge circuit and constant-voltage charge circuit and it's showed as the picture 5-77. The power supply constant-voltage circuit is composed of power supply transformer,T,commutation diode,VDl-VD4,filter capacitor,CI and C2 and three-terminal voltage control IC1.
