BATTERY CONTROL CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/071388
Kind Code:
A1
Abstract:
A battery control circuit and an electronic device, the battery control circuit being used in an electronic device having N batteries, the control circuit comprising a controller (101), N power switches, and N-1 power diodes; one end of the N power switches is respectively connected in series to the output end of the N batteries; the other end of a first power switch is respectively connected to an input end of a power source and the anode of a first power diode; the other end of an i-th power switch is respectively connected to the cathode of an i-1-th power diode and the anode of an i-th power diode; the other end of an N-th power switch is respectively connected to the cathode of an N-1-th power diode and a power supply terminal of the power circuits in the electronic device; and an N-th first output end of the controller (101) is respectively connected to a control end of the N power switches, and is used for controlling the connection state of the N power switches. The battery control circuit and electronic device can prolong the service life of the batteries and enhance the system performance of the electronic device.
