Wireless energy transmission method and system

Abstract

The embodiment of the invention provides a wireless energy transmission method and system. The wireless energy transmission method comprises the steps that relevant information of wireless energy transmission between a first energy sending end and a first energy receiving end is received, and wireless energy transmission is conducted on the first energy receiving end according to the relevant information. According to the wireless energy transmission method and system, when a wireless energy transmission obstacle happens to the wireless energy transmission between the energy sending end and the energy receiving end, the power for the wireless energy transmission can be improved, and then normal wireless energy transmission to the energy receiving end is recovered.

AI Technical Summary

Problems solved by technology

[0004] In the process of wireless energy transmission, there may be a variety of obstacles that cause the power of wireless energy transmission between the energy sending end and the energy receiving end to decrease

For example, if Figure 2a As shown, if there is an obstruction between the energy transmitting end Tx1 and the energy receiving end Rx1 during the wireless energy transmission process, the power of the wireless energy transmission will be significantly reduced; Figure 2b As shown, if there are other energy receiving terminals Rx2 within the energy transmission range of the energy transmitting terminal Tx1, the energy transmitting terminal Tx1 will transmit energy to multiple energy receiving terminals Rx1 and Rx2 at the same time. ”, the power of the wireless energy transmission received by the first energy receiving end Rx1 will be significantly reduced
