Abstract

본 발명은 주전원개폐장치내에 배터리 전압, 전류 및 온도 검출기능을 부가하여 기능이 다양화된 전기자동차용 주전원 개폐장치에 관한 것으로, 종래에는 주전원 개폐기가 단순히 주 전원의 개폐기능만 구비되어 다양한 기능의 요구에 부응하지 못하였다. 본 발명은 차량제어기(16)의 제어신호에 의해 보조 전지(12)의 전원으로 동작되는 메인 릴레이(18,20)가 주 전지(10)의 공급전원을 개폐하도록 주 전지(10)와 모터제어기(14) 사이에 설치됨과 더불어 주 전지(10)와 메인 릴레이(18)사이에 메인 퓨우즈(30)가 설치되고, 또한 상기 주 전지의(10) 전압과 전류 및 온도를 감지하여 차량제어기(16)로 송출되도록 전압변환모듈(22)과 전류변환모듈(24) 및 온도변환모듈(26)이 각각 설치되며, 상기 전압변환모듈(22)과 전류변환모듈(24) 및 온도변화모듈(26)의 각 구동전원을 위하여 보조 전지(12)의 전원을 직류/직류 변환하여 각 모듈에 공급하도록 직류/직류변환기(28)가 설치되어 이루어진 발명임.The present invention relates to a main power switching device for an electric vehicle in which a function is diversified by adding a battery voltage, current and temperature detection function in a main power switching device. It did not meet the demand. According to the present invention, the main relay 10 and the motor controller operate such that the main relays 18 and 20 operated by the power supply of the auxiliary battery 12 open and close the supply power of the main battery 10 by the control signal of the vehicle controller 16. The main fuse 30 is installed between the main battery 10 and the main relay 18, and also detects a voltage, a current, and a temperature of the main battery 10 to control the vehicle controller ( The voltage conversion module 22, the current conversion module 24, and the temperature conversion module 26 are respectively installed to be outputted to the 16, and the voltage conversion module 22, the current conversion module 24, and the temperature change module 26 are installed. DC / DC converter 28 is installed to supply power to each module by DC / DC conversion of the power of the auxiliary battery 12 for each driving power of the invention.
