Method and system for realizing wireless communication of wireless power transmission system

Abstract

The invention discloses a method and a system for realizing wireless communication of a wireless power transmission system. The method comprises that a transmitting terminal activates a communication channel thereof for data transmission with a receiving terminal to establish communication connection with the receiving terminal, the receiving terminal obtains the state information of loads, packages the state information into a corresponding format according to a predefined communication standard and transmits the packaged state information to the transmitting terminal via the communication channel, and the transmitting terminal adjusts the working state thereof according to the state information of the loads. The method is characterized in that the receiving terminal is capable of feeding back the state information of the loads to the transmitting terminal in real time so that the transmitting terminal is capable of accurately adjusting parameters such as transmission power according to the state of the receiving terminal, and the compatibility of the wireless power transmission devices of different types or from different manufacturers is also realized.

Description

technical field [0001] The present invention relates to the field of wireless power transmission, in particular to a method and system for realizing wireless communication of a wireless power transmission system. Background technique [0002] Wireless power transmission technology, generally using inductive coupling power transmission technology, is a new technology that transfers energy to loads in a non-contact manner through electromagnetic coupling. The principle is as figure 1 As shown, the wireless power transmission system is mainly divided into two parts: the transmitting end and the receiving end. The transmitting end mainly completes the conversion and transmission of electric energy, and the receiving end mainly completes energy picking and voltage stabilization to supply power to the load. The system uses the high-frequency magnetic field excited by the high-frequency current in the transmitter coil to cause electromagnetic induction in the receiver coil to gene...

AI Technical Summary

Problems solved by technology

[0004] First, the receiving end cannot feed back the load status information in real time: if the load status of the receiving end changes or fails to notify the transmitting end, the transmitting end can only infer based on its own relevant parameters, which is prone to erroneous conclusions

When the load at the receiving end drops from full load to no load, if the transmitting end cannot respond to the adjustment in time, the coil voltage at the receiving end will overshoot, and even burn out the components in the circuit

[0005] Second, there is no communication between the transmitting end and the receiving end, and there is no unified communication standard between the transmitting end and the receiving end. As a result, different types of products or wireless power transmission products from different manufacturers cannot be compatible at the same time and cannot be used universally. caused inconvenience
