This application provides a wireless charging board, a wireless charging board misalignment detection method, and a wireless charging system. The wireless charging board includes a power transmitting coil, a detection circuit, a plurality of metal induction coils, and a processor. Each metal induction coil disposed on a second plane in the wireless charging board detects, through induction, whether a metal exists right above the metal induction coil, and generates an induced electrical signal. The processor determines a first detection matrix based on the induced electrical signal generated by each metal induction coil, determines a relative position of the wireless charging board to a chassis of a target vehicle in a chassis metal detection matrix of the target vehicle based on the first detection matrix, and determines charging position misalignment information of the wireless charging board based on the relative position of the wireless charging board to the chassis of the target vehicle. According to this application, an adjustment range during alignment between a target charging working region and the wireless charging board can be expanded, thereby ensuring that a sufficient adjustment space is left for a driver, and achieving high applicability.
