[0022] Please refer to figure 1 , which is a schematic diagram of component connections of the electronic device according to the first embodiment of the present invention. In this embodiment, the electronic device 1 can be used to charge a rechargeable device 9 . The electronic device 1 may include a power supply interruption system 10 and a detection circuit 11 . When the detection circuit 11 detects that the rechargeable device 9 has been fully charged, the power supply interruption system 10 will cut off the charging operation of the rechargeable device 9 . The design of this embodiment can prevent the voltage or current that has been charged in the rechargeable device 9 from gradually flowing back into the power supply and interruption system 10 after a period of time. This kind of situation often occurs when the electronic device 1 itself has the function of automatically switching between the normal mode and the power saving mode to comply with environmental protectio...

[0025] Please refer to figure 2 , the component connection relationship of the electronic device in this embodiment can be as follows figure 2 shown. In this embodiment, the electronic device 2 can be used to charge a rechargeable device 9 . The electronic device 2 may include a power supply interruption system 20 and a detection circuit 21 . When the detection circuit 21 detects that the rechargeable device 9 has not been fully charged and the power supply interruption system 20 is in a shutdown state, the detection circuit 21 controls the power supply interruption system 20 to continue supplying power to the rechargeable device 9 . When a traditional electronic device is turned off, only a small amount of standby power is consumed, and it cannot be charged externally. Often, the charging cannot be continued before the charging is completed, or even half-charged, which causes considerable troubles for users. The design of this embodiment, using the detection circuit 21 f...

[0028] Please refer to image 3 , the component connection relationship of the electronic device in this embodiment can be as follows image 3 shown. In this embodiment, the electronic device 3 can be used to charge a rechargeable device 9 . The electronic device 3 may include a power supply interruption system 30 and a detection circuit 31, and the power supply interruption system 30 may include a power supply unit 301, a voltage backflow prevention unit 302 and a power output unit 303, and the connection relationship is as follows: image 3 As shown; wherein, the power supply unit 301 outputs current to charge the rechargeable device 9 through the voltage backflow prevention unit 302 and the power output unit 303 .

[0029] When the detection circuit 31 detects that the rechargeable device 9 has been fully charged, the detection circuit 31 will send a signal to control the voltage backflow prevention unit 302 so that the power supply unit 301 and the power output unit 303 ...

Abstract

An electronic device for charging a rechargeable device, which includes a power-off system; and a detection circuit electrically connected to the power-off system, wherein when the power-off system is in a power-saving mode, And when the detection circuit detects that the rechargeable device has not been fully charged, the detection circuit controls the power supply interruption system to supply power to the rechargeable device.

Description

technical field [0001] This case proposes an electronic device for charging a rechargeable device and a charging method thereof, in particular a display device for charging a rechargeable device and a charging method thereof. Background technique [0002] With the advancement of technology and the continuous reduction of product prices, many portable electronic products, such as mobile phones, digital cameras, music players (such as: MP3 players), etc., have become more and more common, and even become a part of people's daily life. Indispensable part. Due to the frequent use of these portable electronic products, they generally must be charged frequently. For convenience, some common electrical connection specifications have been developed and formulated, such as the Universal Serial Bus (USB) specification, the Institute of Electrical and Electronics Engineers 1394 (IEEE 1394) specification, and the like. Therefore, users can charge these portable electronic products as ...
