Abstract:
A charge control device includes a control circuit configured to monitor a charge voltage and a charge current of a battery and perform output feedback control upon the charge voltage and the charge current to thereby achieve constant voltage charge or constant current charge of the battery; and an adjusting circuit configured to adjust the output feedback control of the control circuit based on charge state information of the battery obtained by a gas gauge device.
