Wireless charging system and charging method based on electromagnetic wave

Abstract

The invention relates to a wireless charging system and a charging method based on an electromagnetic wave. The wireless charging system based on the electromagnetic wave comprises a transmitting device and a receiving device arranged on an electronic device. The transmitting device comprises a signal generating module, a transmitting antenna, a first monitoring module and a position monitoring module. The signal generation module is connected with an external power supply. The first monitoring module is used for acquiring and judging the working parameters of the external power supply, the signal generation module and the transmitting antenna. The position monitoring module monitors the position parameters and the working parameters of the transmitting antenna. The receiving device comprises a receiving antenna, a conversion unit and a second monitoring module. The second monitoring module obtains the position parameter of the receiving antenna and feeds back to the position monitoring module, and is used for obtaining and judging the working parameter of the analysis conversion unit to feed back to the external power supply, so that the external power supply adjusts the working parameter. The wireless charging system based on electromagnetic wave can realize point-to-point energy transmission and improve charging efficiency.

[0002] At present, electronic devices have become an indispensable part of daily life, and a wide variety of electronic devices also bring complicated charging lines, and the inconvenience of carrying and organizing charging lines and the adaptability of different electronic devices have affected consumers. Therefore, the demand for wireless charging in the field of consumer electronics is increasing day by day

In the prior art, there are mainly two wireless charging methods of magnetic resonance coupling and electric field induction, but both of these two methods have strict restrictions on the induction distance and charging position, and cannot meet the requirements of wireless charging in the true sense; in addition, due to the coil The type coupling conflicts with the metal casing of the electronic device, so that the casing of the electronic device can only be made of glass or ceramics to solve this problem, but the processing cost of the casing made of glass or ceramics is relatively high, and the processing technology is immature. At the same time, there are also the disadvantages of being easy to break and break
