According to the present invention, provided is a wireless charger for an electric vehicle, capable of increasing the supply rate of electric vehicles by enabling an electric vehicle to be wirelessly charged during driving or when parked through a charge transfer between a power transmission panel installed on a road and an electrification panel installed in the electric vehicle; solving concerns about environmental pollution by enabling the driving of an electric vehicle without using fossil energy (gasoline or diesel oil); and embodying the construction of a charging infrastructure which does not cause a waste of time consumed for charging. According to the present invention, the wireless charger includes: a power transmission panel buried under the surface of a road while kept electrically connected with a high-frequency oscillator; an electrification panel installed in the bottom of an electric vehicle to be opposed to the power transmission panel such that charges can be transferred; a rectification means rectifying the charges transferred to the electrification panel to provide an AC current as a DC current; and a charging means charging the DC current rectified by the rectification means into a battery.
본 발명은 도로에 설치된 송전패널과, 전기자동차에 설치된 대전패널 사이의 전하 이동을 통해서 전기자동차에 무선으로 충전이 이루어져 주행 중이나 주차 중에 무선충전이 제공될 수 있도록 함으로 해서 전기자동차 보급률을 높이고 화석에너지(휘발유 또는 경유) 사용 없이 전기자동차의 운행이 이루어질 수 있어 환경오염 염려도 일소할 수 있으며, 충전에 따른 시간 낭비 없는 충전 인프라 구축을 실현할 수 있도록 한 전기자동차용 무선충전장치를 제공코자 하는 것이다. 즉, 본 발명은 고주파발진기와 전기적으로 연결된 상태로 도로의 노면 아래쪽에 매설된 송전패널과; 상기 송전패널과 대향하도록 전기자동차의 저면에 설치되어 전하 이동이 이루어지도록 한 대전패널과; 상기 대전패널로 이동된 전하를 정류하여 AC전류를 DC전류로 제공하는 정류수단과; 정류수단에서 정류된 DC전류를 배터리에 충전하는 충전수단을 포함하는 것이다.
