Embodiment 1

[0044] According to an embodiment of the present invention, an embodiment of a wireless charging method is also provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, although A logical order is shown in the flowcharts, but in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0045] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Take running on a computer terminal as an example, figure 1 It is a hardware structure block diagram of a computer terminal of a wireless charging method according to an embodiment of the present invention. Such as figure 1 As shown, the computer terminal 10 may include one or more (only one is shown in the figure) processors 102 (the p...

Embodiment 2

[0064] Figure 4 is a structural block diagram of a wireless charging system according to Embodiment 2 of the present invention. Such as Figure 4 As shown, in the embodiment of the present invention, a wireless charging system is also provided, including:

[0065] The energy receiving end 40 is connected to the load 42 for determining the required power of the load 42, and sending an indication message to the energy transmitting end, wherein the indication message is used to indicate the determined required power of the load;

[0066] The energy transmitting end 44 is used to adjust the charging energy according to the indication message, and transmit the adjusted charging energy to the energy receiving end 40, wherein the transmission channel of the indication message and the transmission channel of the charging energy are independent of each other.

[0067] Through the above system, the energy receiving end determines the required power of the load, and sends an indicatio...

Abstract

The invention provides a wireless charging method and system, wherein, the method comprises the following steps: an energy receiving end determines the required power of a load; the energy receiving end sends an indication message to an energy transmitting end, wherein the indication message is used for indicating the required power of the determined load; the energy receiving end receives the charging energy emitted by the energy emitting end, wherein, the charging energy emitted by the energy emitting end is the charging energy adjusted by the energy eitting end according to the indication message, and the indication message transmission channel and the charging energy transmission channel are mutually independent. By adopting the technical scheme, the problem that the energy emitting end of the wireless charger cannot effectively adjust the energy output according to the power change of the load in related technologies is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a wireless charging method and system. Background technique [0002] Wireless charging technology (Wireless charging technology; Wireless charge technology), derived from wireless energy transmission technology, low-power wireless charging often uses electromagnetic induction (such as the Qi method for charging mobile phones), high-power wireless charging often uses resonance (most electric Car charging adopts this method) The power supply equipment (charger) transmits energy to the device that uses electricity, and the device uses the received energy to charge the battery and at the same time for its own operation. [0003] Since energy is transmitted between the charger and the power-consuming device by a magnetic field, the two are not connected by wires, so both the charger and the power-consuming device can have no exposed conductive contacts. [0004] At present, the wir...
