Abstract:
A wireless power transmission device for a vehicle and a method are provided. The wireless power transmission device for a vehicle may transmit a signal for detection of a wireless power reception device by using a lower frequency band that is different from an operating frequency band used to control the vehicle. The wireless power transmission device may receive a response signal for the transmitted signal and a power control signal from the wireless power reception device. The wireless power transmission device may control an operating frequency or a voltage (or both) in the wireless power transmission device for the vehicle according to the power control signal. The wireless power transmission device may transmit wireless power to the wireless power reception device.
