Problems solved by technology

However, in actual use, the power consumption of the device is closely related to the degree of use of the application service. For example, if a smartphone is only used for calls, it can be used for more than two days, but if it is used as a wireless terminal, the audio / video Download and playback, web browsing, photo taking and other applications can only be used for one day
[0004] Existing wireless charging technology cannot meet users' differentiated power demands

Embodiment 1

[0108] figure 1 A flowchart showing the wireless charging method according to the first embodiment of the present invention. Such as figure 1 As shown, the wireless charging method mainly includes:

[0109] Step S1, the charging device receives power usage data sent by at least one wearable device.

[0110] The wearable device acquires its own power usage data and sends the power usage data to the charging device. The charging device receives the power usage data.

[0111] Step S2, the charging device determines a power distribution plan according to the power usage data, and the power distribution plan is used to determine the charging sequence and charging power for the charging device to charge the wearable device.

[0112] Step S3, the charging device wirelessly charges the wearable device according to the power distribution scheme.

[0113]According to the wireless charging method provided by the embodiment of the present invention, the charging device determines t...

Embodiment 2

[0115] refer to figure 1 , shows a flow chart of the wireless charging method according to the second embodiment of the present invention. The difference between this embodiment and the previous embodiment is that after step S2, a step S4 is further included in which the charging device sends the power distribution scheme to the wearable device. The method is specifically:

[0116] Step S1, the charging device receives the power usage data sent by the wearable device.

[0117] Power demand data is obtained by wearable devices and reflects its own power demand data, which can be current power (c), power consumption rate (c / s), remaining power ratio (%), full power standby time (s) and One or more items in data such as average power consumption rate (c / s).

[0118] The wearable device obtains its own power usage data. Taking the current power as an example, the wearable device obtains its own current power and sends it to the charging device. The charging device receives th...

Embodiment 3

[0136] Figure 4 A flow chart of the wireless charging method according to the third embodiment of the present invention is shown. Such as Figure 4 As shown, the wireless charging method mainly includes:

[0137] Step S101, the first wearable device 10 acquires power usage data.

[0138] The power usage data of the wearable device is related to the current business type, power consumption level, business expected duration and battery power reserve. Among them, the type of business reflects the characteristics of power consumption. For example, the power consumption of flashlights for taking photos is sudden power consumption; the power consumption of video playback mainly lies in the brightness of the screen display and the duration of video playback; the power consumption of web browsing mainly includes two parts: screen display and wireless network.

[0139] Step S102 , the first wearable device 10 sends power usage data to the charging device 30 .

[0140] The first we...

Abstract

Provided are a wireless charging method and system, a wireless charging device and a wearable device. The method comprises: a charging device receiving electric power usage data sent by at least one wearable device; according to the electric power usage data, the charging device determining an electric power allocation solution, the electric power allocation solution being used for determining the charging order and charging electric power for charging of the wearable device by the charging device; and the charging device conducting wireless charging on the wearable device according to the electric power allocation solution. By means of the wireless charging method provided in the present invention, the relationship between the actual electric power demand of a user and the charging capability allocation can be coordinated, thereby realizing the overall arrangement of electric power among a plurality of wearable devices and the dynamic allocation of the charging capability.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless charging method and system, a wireless charging device and a wearable device. Background technique [0002] At present, wearable devices are developing rapidly due to their portability and other advantages. However, the size and weight of wearable devices limit the battery capacity, resulting in short standby time and affecting user experience. For example, Google Glass (Google Glass) is equipped with a 570mh battery, which can only be used for 3 to 4 hours. At the same time, wireless charging is receiving more and more attention for its convenience of charging. [0003] The existing wireless charging technology is just a simple replacement of the wired charging method. In the work of the existing wireless charging equipment, the charging process is independent of user services. However, in actual use, the power consumption of the device is closely rela...
