Advanced Wireless Charging Technology

Dear Colleagues,

With the improvement of people's pursuit of portability, safety, and reliability, the traditional “plug-in” charging method can no longer meet the needs of people's life. Wireless charging technology refers to a technology that uses corresponding equipment to send and receive inductive AC signals at the sending and receiving ends without the use of electrical wires. The technology has shown wide application prospects in different fields from milliwatts to megawatts and from near-field to far-field. Due to its safety, portability, and reliability, wireless charging has been widely used in some applications, especially for low-power consumer electronic products. However, with the concern on transfer efficiency, misalignment tolerance, charging power adjustment, and thermal reliability, the progress of wireless charging in high-power industrial applications is still slow. In order to advance the application process of wireless charging, the performance on high efficiency, strong misalignment tolerance, and thermal safety need to be further studied, including innovative work on compensation networks, loosely coupled transformers, circuit structures, control methods, thermal modeling, and charging profile optimization. The research goal is to solve the theory and practice problems of high-power wireless charging systems, especially for electric transportation, smart grid, automatic guided vehicles, industrial sensors, and other applications. Topics of interest for publication include, but are not limited to, the following:

• Wireless charging for electric vehicles;
• Wireless charging for industrial sensors;
• Wireless charging for industry vehicles, such as automatic guided vehicles;
• Wireless charging for underwater autonomous vehicles;
• Wireless charging control methodology;
• Dynamic wireless charging;
• Compensation circuit design for wireless charging;
• Magnetic coupler design for wireless charging;
• Thermal modeling and design for wireless charging;
• Optimal charging technology.
