Research on Power Supply and Communication Methods for Wireless Power Transmission Systems

This paper describes a power supply and communication method for a wireless power transmission system. Autonomous Underwater Vehicles (AUVs) can charge at multiple wireless charging stations with specified power levels simultaneously. Three cylindrical wireless power transmission stations (one master station and two slave stations), each with a capacity of 5 kilowatts, are designed to accommodate various types of AUVs, including cylindrical, cuboid, and biomimetic marine life shapes. Communication is conducted through both wireless information transmission and RS-485 wired communication methods. The charging status is monitored by the underwater wireless power transmission stations, which use wireless information transmission to collect battery charging parameters. An experimental platform has been built to verify theoretical analysis and simulation results. The three underwater wireless power transmission stations can communicate with each other and are controlled by a shore-based control center, enabling real-time control over the system's charging status and power flow.
