Abstract: A battery control circuit is applied to an electronic device having N batteries. The battery control circuit includes: a controller, N power switches, and (N?1) power diodes; one end of the N power switches is respectively connected in series with an output end of the N batteries; the other end of a first power switch is connected to an input end of a power source and the anode of a first power diode respectively; the other end of an i-th power switch is connected to the cathode of an (i?1)-th power diode and the anode of an i-th power diode respectively; the other end of a N-th power switch is connected to the cathode of a (N?1)-th power diode and the power supply end of each electric circuit in the electronic device; N first output ends of the controller are respectively connected to control ends of the N power switches, for controlling an ON/OFF state of the N power switches.
