Problems solved by technology

The battery life of electronic devices has become a major obstacle to its development. For example, while enjoying the wonderful life brought by the powerful functions of smart phones, users also strongly feel that the battery's endurance is not enough, so they often encounter The embarrassing situation where the battery needs to be charged
[0003] When an electronic device needs to be charged, it is necessary to look for a power source that can charge the electronic device. Generally, there are two methods: wired charging and wireless charging; when the power source is another electronic device, more attention will be paid to the output Power, and the remaining power of the electronic device; but in the existing charging process, the power of the transmission cannot be controlled

Embodiment 1

[0029] A charging control method according to a method embodiment of the present invention is applied to a first electronic device, and the first electronic device can transmit electric energy to a second electronic device in a wireless or wired manner, figure 1 It is a schematic diagram of the implementation flow of the method embodiment 1 of the present invention, as figure 1 As shown, the method includes:

[0030] Step 101, during the process of transmitting electric energy, detecting the transmitted electric energy or remaining electric energy;

[0031] Here, the electronic devices include, but are not limited to: portable notebooks, tablet computers, mobile phones, e-readers, digital cameras, video cameras, and the like.

[0032] Here, the wired charging method is the most common charging method, which includes: connecting the first electronic device to the second electronic device through a charging cable, and the first electronic device is used to charge the second ele...

Embodiment 2

[0043] A charging control method according to a method embodiment of the present invention is applied to a first electronic device, and the first electronic device can transmit electric energy to a second electronic device in a wireless or wired manner, figure 2 It is a schematic diagram of the implementation process of the second embodiment of the method of the present invention, as figure 2 As shown, the method includes:

[0044]Step 201, during the process of transmitting electric energy, detecting the transmitted electric energy or remaining electric energy;

[0045] Step 202, judging whether the transmitted electric energy or the remaining electric energy reaches a predetermined first threshold, and obtaining a first judging result;

[0046] Step 203, when the first judgment result indicates that the transmitted electric energy or the remaining electric energy reaches a predetermined first threshold, generating a first instruction;

[0047] Step 204, stop the transmis...

Embodiment 3

[0050] A charging control method according to a method embodiment of the present invention is applied to a first electronic device, and the first electronic device can transmit electric energy to a second electronic device in a wireless or wired manner, image 3 It is a schematic diagram of the implementation process of the third embodiment of the method of the present invention, as image 3 As shown, the method includes:

[0051] Step 301, during the process of transmitting electric energy, detecting the cumulative output current or the percentage of remaining power of the first electronic device;

[0052] Here, as in Example 1: Assume that the first electronic device currently has a current of 2000 milliamps (mA), and the second electronic device currently has a current of 200 mA, and now the first electronic device intends to transmit a current of 900 mA to the second Electronic equipment; therefore, during the process of transmitting electric energy, the cumulative output...

Abstract

The invention discloses a charging control method. The charging control method is applied to first electronic equipment, and the first electronic equipment is used for transmitting electric energy to second electronic equipment in a wired or wireless way. The charging control method comprises the following steps of in the electric energy transmitting process, detecting the transmitted electric energy or the remained electric energy; judging whether the transmitted electric energy or the remained electric energy reaches the preset first threshold value or not, so as to obtain a first judging result; when the first judging result shows that the transmitted electric energy or the remained electric energy reaches the preset first threshold value, generating a first instruction; according to the first instruction, stopping the transmitting of the electric energy. The invention also discloses electronic equipment. By adopting the technical scheme, the electric amount of charging can be controlled in the charging process.

Description

technical field [0001] The invention relates to the charging technology of electronic equipment, in particular to a charging control method and electronic equipment. Background technique [0002] With the development of technology, electronic devices can support more and more functions. For example, mobile phones have evolved from the simple functions of calling and sending text messages in the early days to tens of thousands of software applications today. The battery life of electronic devices has become a major obstacle to its development. For example, while enjoying the wonderful life brought by the powerful functions of smart phones, users also strongly feel that the battery's endurance is not enough, so they often encounter An awkward situation where the battery needs to be recharged. [0003] When an electronic device needs to be charged, it is necessary to look for a power source that can charge the electronic device. Generally, there are two methods: wired charging...
