차량용 무선전력 전송장치 및 무선 충전 방법을 제공한다. 차량용 무선전력 전송장치에 의한 무선 충전 방법은 차량의 제어에 사용되는 동작 주파수 대역 보다 낮은 주파수 대역을 사용하여 무선전력 수신장치의 검출을 위한 신호를 전송하는 단계, 상기 무선전력 수신장치로부터 상기 전송된 신호에 대한 응답 신호 및 전력 제어 신호를 수신하는 단계, 상기 전력 제어 신호에 따라 동작 주파수와 상기 차량용 무선전력 전송장치 무선전력 전송장치 내의 전압 중 적어도 하나를 제어하는 단계 및 상기 무선전력 수신장치로 무선전력을 전송하는 단계를 포함할 수 있다.
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.
