Abstract

The invention discloses a wireless charging method, device and system, relating to the field of application of electronic devices. The problem that the coupling degree is reduced in the wireless charging process can be solved. The wireless charging method comprises the steps of: obtaining coupling characteristic information of an opposite end, wherein the coupling characteristic information is used for representing a coupling degree of receiving and transmitting an electromagnetic wave signal between a local end and the opposite end; and determining the frequency of the local end according to the coupling characteristic information so that the frequency of the local end is optimally matched with that of the opposite end. The wireless charging method, device and system is mainly applied to the process of wirelessly charging electronic devices such as a mobile phone and a computer.

Description

technical field [0001] The present invention relates to the application field of electronic equipment, in particular to a wireless charging method, device and system. Background technique [0002] Wireless charging technology mainly transmits electric energy through electromagnetic waves. A typical wireless charging system includes a transmitting end for sending electromagnetic waves (such as a charging base) and a receiving end for receiving electromagnetic waves (such as a device to be charged). The transmitting end and the receiving end transmit and receive electromagnetic waves through electromagnetic induction or magnetic field resonance, thereby realizing the transfer of electric energy. With the increasing maturity of wireless charging technology and the continuous expansion of its application scope, wireless charging technology has attracted more and more attention from electronic equipment manufacturers, and has received great attention in the fields of mobile phone...
