摘要： An electronic device includes a first rechargeable battery, a solar cell mounted on the electronic device, a second rechargeable battery and a power management circuit. The power management circuit includes a control module, a DC/DC module, a switch and a power supply switching module. The DC/DC module is configured for converting the DC power generated by the solar cell from one voltage level to another, and activating and maintaining the activation of the control module. The switch is turned on by the control module when the control module is activated, causing the DC power from the DC/DC module to charge the second rechargeable battery. The power supply switching module is controlled by the control module to select the second rechargeable battery to power the electronic device if the voltage level of the rechargeable battery is lower than that of the second rechargeable battery.

摘要： An exemplary electronic device capable of automatically selecting a power source includes two power ports configured to connect to external power sources and a battery compartment configured to receive a battery module. The voltage of the battery module is higher than at least one of the external power sources. The electronic device further includes a power selection module allocated between the battery module and the power port which selects the lower voltage. Three diodes are respectively located on the output path of the three power sources. A path switch that controls whether power to the device comes from the battery compartment or a power port is located between the anode of the battery compartment and the diode located on the output path of the battery module. Among the multiple power sources, the external power source providing a higher voltage is the first to be chosen to power the electronic device.

摘要： The present invention provides a battery charging control circuit to charge batteries in phases. In a first charging phase the charging circuit charges the batteries with a large current and at a second charging phase the charging circuit charges the batteries with a much smaller current. The charging circuit includes a current detection circuit which detects a charge current and provides a detection voltage proportional to the charge current. The battery charging control circuit also includes an amplifier circuit to amplify the detection voltage and a comparison module compares the amplified detection voltage with a reference voltage. If the amplified detection voltage is lower than the reference voltage, the comparison module outputs a switch signal to a control module. The control module controls a charging module to charge the battery in a trickle mode when receiving the switch signal.
