Efficiency improvement method and device based on microwave wireless charging

Abstract

The invention is applicable to the technical field of wireless charging, and provides a microwave wireless charging-based efficiency improvement method and device. The microwave wireless charging-based efficiency improvement method comprises the steps of firstly, building a first attenuation model of a receiving distance and receiving power between a charging node and equipment to be charged, andbuilding a second attenuation model of a receiving deflection angle and receiving power of an antenna between the charging node and the equipment to be charged; secondly, calculating the receiving power between the charging node and the equipment to be charged by combining the first attenuation model and the second attenuation model; and finally, dividing a plurality of charging nodes, and optimizing the plurality of charging nodes after division by a local optimization mode combined with the receiving power to obtain optimized maximum value of the receiving power, wherein the maximum value isused as maximum receiving power between the charging node and the equipment to be charged. With the method provided by the invention, maximum charging efficiency of each charging node is ensured, andresource waste is prevented.

Problems solved by technology

In the first two modes, the goal of power maximization can only be achieved by optimizing the adjustment for a certain device to be charged; while the last mode, the many-to-many charging mode, is the most common mode of microwave wireless charging, that is, in In practical applications, the microwave-based wireless charging method is often aimed at multiple receiving devices, and this mode often lacks the communication between the transmitting end and the receiving end for the two main factors affecting the transmission distance and the deflection angle between the transmitting and receiving devices. Matching optimization scheme, lack of optimization of energy transmission, resulting in low efficiency of microwave wireless charging and a lot of energy waste
