This technology breaks through the performance limitation of traditional wireless charging from the level of magnetic circuit reconstruction, greatly expands the effective charging area, significantly improves the anti-offset stability, and realizes the compatibility and intercommunication between mainstream coil structures such as square and double rectangle (DD). The system maintains high efficiency power transmission under offset conditions, and has the potential of engineering application. This achievement provides a new technical route for a wide-range and strong interoperability wireless charging system, and is of great significance to promote the industrialization of wireless power transmission technology in electric vehicles, intelligent equipment and other fields.
