Abstract

본 발명은 전기 자동차의 이상 여부 검출장치에 관한 것으로, 동력원을 전달하는 전원 케이블의 임의의 부분이 단락되어 바디(Body)에 접촉되어 있을시 발생되는 전압 강하를 통해 전원 케이블의 단락 상태를 검출하여 운전자ㅓ에게 통보하도록 한 것이다.The present invention relates to a device for detecting an abnormality of an electric vehicle, and detects a short circuit state of a power cable through a voltage drop generated when an arbitrary portion of a power cable that transmits a power source is shorted to contact a body. It was to inform the driver.

본 발명은 배터리의 전원을 전기 자동차의 각 구동부측에 인가하는 전원 케이블의 단락시 발생되는 전압 강하를 통해 누전 여부를 검출한 후 운전자에게 지시하므로 전기 자동차의 운행에 신뢰성을 제공하여 안전사고를 배제한다.The present invention provides a reliability to the operation of the electric vehicle by eliminating safety accidents by instructing the driver after detecting a short circuit through a voltage drop generated when a power cable is applied to each driving unit of the electric vehicle. do.
