Abstract

The importance of electric vehicles is gradually increasing due to the recent depletion of fossil fuels. In order to use an electric vehicle, the battery built into the vehicle must be frequently charged. Electric vehicles has very good performance in terms of noise and vibration. However, due to the limitations of the battery, the mileage is considerably shorter than that of an internal combustion engine vehicle once it is charged, and the battery charging time is relatively long compared to the refueling time. There are two types of charging methods for electric vehicle batteries: plug-in and wireless charging. In this paper, we introduced the wireless charging technology for electric vehicles and the current state of technology development and standards in major countries.

최근 화석연료의 고갈로 인해 전기 자동차의 중요성이 점차 커지고 있다. 전기 자동차를 사용하기 위해서는 자동차에 내장된 배터리를 수시로 충전해야 한다. 전기 자동차는 소음, 진동에 있어 매우 뛰어난 성능을 구현한다. 하지만 배터리의 한계상 1회 충전 시 주행거리가 내연 자동차보다 상당이 짧으며, 배터리 충전 시간도 주유 시간에 비해 상대적으로 매우 오래 걸린다는 단점이 있다. 전기 자동차용 배터리를 충전하는 방식은 플러그인 방식과 무선 충전 방식이 있다. 본 논문에서는 전기 자동차용 무선 충전 기술에 대한 소개와 주요 국가의 기술 개발 현황 및 표준을 소개하였다.
