We verified the improvement of the overall performance of WPT system by the HTS coil through theoretical analysis and simulation and designed a HTS WPT suspension device, which can realize stable suspension while efficiently transmitting the charged objects, and solve the existing technology through electromagnetic or electric suspension, and the need for built-in power or battery caused by the device is complex, easy to lateral deviation, low sustainability and so on. It can be widely used in all kinds of mobile charging, publicity and display scenes, and opens up a new idea for the application of superconducting WPT technology.
