Wireless power supply method with communication key matching

Abstract

The invention belongs to the technical field of wireless power supply, particularly relates to a wireless power supply method with communication key matching, and aims to solve the problem of low safety of the existing wireless power supply. The wireless power supply method comprises the steps that an energy supply end A and an energy receiving end B are respectively provided with an electromagnetic wave transmitting and receiving device and a key module, when a system works, the receiving end B searches the position of the supply end A firstly, a secret key module is used for carrying out secret key matching with the supply end, the receiving end B uses an electromagnetic wave generator to generate a request electromagnetic wave Y, processes the request electromagnetic wave Y and then transmits the processed electromagnetic wave Y to the supply end A, and the receiving end B receives an electromagnetic wave X and then converts the electromagnetic wave X into electric energy. According to the wireless power supply method , through setting the key matching mode, a function supply relation between the energy supply end A and the energy receiving end B is carried out, so that the safety of wireless power supply can be effectively improved, the phenomena of electricity stealing and electricity leakage are effectively prevented, and the establishment and improvement of a charging system in the wireless power supply use process are facilitated.

Description

technical field [0001] The invention relates to the technical field of wireless power supply, in particular to a wireless power supply method with communication key matching. Background technique [0002] In recent years, the research and development of the technology of using electromagnetic waves (microwaves) to transmit power has become a hot spot. Most of the existing technologies are short-distance wireless power supply systems that use electromagnetic induction or magnetic resonance and are less than a few meters away. The method of wireless power transmission at the energy receiving end, wireless power supply, is a convenient and safe new technology that does not require any physical connection, and electric energy can be transmitted to the load at close range without contact. [0003] Due to the popularization of wireless power supply technology, in the existing technology, as long as the distance between the energy receiving end and the energy providing end is withi...

AI Technical Summary

Problems solved by technology

[0003] Due to the popularization of wireless power supply technology, in the existing technology, as long as the distance between the energy receiving end and the energy providing end is within the coverage range, charging and power supply can be performed without the certification and permission of the energy receiving end, which will lead to different energy receiving ends. The phenomenon of random charging occurs, and the overall safety is low. Therefore, corresponding improvements are made to address this problem
