Problems solved by technology

[0005] In the existing wireless charging scheme, the design structure of the control module is complicated, and the control method is not easy to realize. In the process of detection and control startup, the power consumption is large, the detection range is small, and the scope of application is limited.
At the same time, the existing wireless charging scheme must use a wireless charging chip with a protocol, as well as supporting receiving and transmitting antennas, according to the manufacturer's reference scheme, to detect the existence of the receiving module, which is costly
