[0002] In the process of the intelligent development of modern vehicles, an integrated in-vehicle wireless charging device has emerged. It integrates the wireless charging device with the in-vehicle central control panel or armrest box, etc., greatly improving the integration degree inside the vehicle and bringing a convenient charging experience to users.
