Abstract

$CO_2$ reduction, energy security, and emission reduction are the critical issues in the current automotive industry. As one of the solutions to these issues, Battery Electric Vehicle is attracting attention recently. Advanced battery electric drive vehicle require batteries, power electronics and electrical machines to function. These devices allow the vehicle to use energy from the battery to assist in the propulsion of the vehicle. In this paper, the main feature of these technologies are briefly introduced and recent trends of patent applications are described.

자동차산업이 해결해야 과제로서 $CO_2$배출에 의한 지구온난화, 배기가스배출에 의한 도시부 대기오염 그리고 석유자원고갈 등에 대한 대처 등이 있다. 이들의 현실적인 해법으로 시장에서 높은 평가를 받고 있는 것이 배터리전기자동차이다. 배터리전기자동차의 핵심 기술은 모터, 배터리, 전력제어, 전기적 제동 기술 등이다. 본 연구에서는 전기자동차에 대한 각국 정부의 주요 정책현황, 메이저 자동차 메이커의 판매전략, 핵심 요소기술의 개발동향 및 기술분석, 그리고 이들 기술들에 대한 세계특허출원동향을 조사분석하였다.
