A static wireless charging auxiliary alignment positioning device and method

Abstract

The application provides a static wireless charging auxiliary alignment positioning device and a positioning method. The device comprises a transmitting end device and a receiving end device. The transmitting end device comprises a wireless transmitting plate and a charging pile. The wireless transmitting plate is integrated with a transmitting end power coil, a three-dimensional Hall sensor array and an infrared distance measuring module. The charging pile is internally provided with a servo motor adjusting mechanism, a control unit and a first communication module. The receiving end device comprises a heterogeneous permanent magnet array integrated in a wireless receiving plate, a receiving end power coil and a second communication module. The heterogeneous permanent magnet array is arranged at the periphery of the receiving end power coil. The second communication module is connected with the first communication module through wireless communication. The transmitting end power coil is resonantly matched with the receiving end power coil. The application significantly improves the positioning accuracy and system robustness, and can adapt to the chassis height of different vehicle models to ensure the efficiency and stability of wireless charging.
