Title: WIRELESS CHARGING DEVICE, COIL SWITCHING METHOD THEREFOR, AND RELATED DEVICES
Abstract:
A wireless charging device, a coil switching method therefor, a charging station and a smart garage, the charging device comprising: a phase detecting module and at least two wireless charging transmitting coils (3, 4)/wireless charging receiving coils (1, 2); the wireless charging transmitting coils (3, 4)/wireless charging receiving coils (1, 2) are arranged in parallel according to a preset interval; both the charging station and the smart garage comprise the wireless charging device. The wireless charging device, the coil switching method therefor, the charging station and the smart garage may ensure that, when the positions of wireless charging receiving coils (1, 2)/wireless charging transmitting coils (3, 4) which correspond to the wireless charging transmitting coils (3, 4)/wireless charging receiving coils (1, 2) change, the interval between the wireless charging transmitting coils (3, 4)/wireless charging receiving coils (1, 2) and the wireless charging receiving coils (1, 2)/wireless charging transmitting coils (3, 4) which correspond thereto may reach a set wireless charging distance such that electrical energy transmission may be performed according to the maximum power transmission efficiency.
