More than 2 butteries are charged successively and rapidly by one power supply. The circuit includes a power supply (10) for supplying the charge voltage to a battery, a power switching unit (12) for switching the power to supply the power to one battery, a switching control unit (14) for providing the switching control signal to the switching unit so that the charge voltage is switched to the batteries sequentially, a battery detector (16) for detecting the battery in holders a display (20) for displaying the charge of a battery provided the charge voltage, and a microcomputer (22) for providing the charge mode control signal and the battery selection signal to the switching control unit (14), the display control signal to the display and for changing the battery selection signal when the charge completion signal is received from a delta V sensor (18). |
