Abstract

목적purpose

본 발명은 전기자동차를 장기간 방치해 두었을 때 보조배터리의 과방전을 방지하면서도 키온시 문제점이 없도록 한 전기자동차의 보조배터리 방전 제어 장치에 관한 것이다.The present invention relates to an auxiliary battery discharge control device for an electric vehicle that prevents an overdischarge of an auxiliary battery when an electric vehicle is left unattended for a long period of time, but does not have a problem in key-on.

구성Configuration

본 발명은 보조 배터리(10)와 직류/직류 전원부(DC/DC)(20) 및 보조부하(30)를 연결/차단하기 위한 릴레이(40)와, 그 릴레이(40)를 제어하기 위한 타이머(51) 및 릴레이 제어부(50)와, 상기한 보조배터리(10)의 충전전압을 감지하는 전압 센서(60)와, 그 전압센서(60)의 전압 감지에 의해 상기한 릴레이 제어부(50)를 제어하되, 키온시 일정전압 이상으로 충전되면 릴레이(40)를 오프시키고, 키 오프시 일정전압 이하로 떨어지면 릴레이(40)를 오프시켜 보조배터리(10)의 과방전을 방지하도록 제어하는 시스템 콘트롤러(70)와, 키온시 상기한 보조 배터리(10) 전원을 키온(KEY ON) 및 배터리 단자(B+)에 인가시키는 노어말 단락 키 스위치(80)로 구성됨에 특징이 있다.The present invention includes a relay 40 for connecting / disconnecting the auxiliary battery 10, the DC / DC power supply 20 and the auxiliary load 30, and a timer (not shown) for controlling the relay 40 And a relay controller 50. The voltage sensor 60 senses the charging voltage of the auxiliary battery 10 and controls the relay controller 50 by sensing the voltage of the voltage sensor 60. [ A system controller 70 for controlling the relay 40 to be turned off when the voltage of the battery 14 is higher than the predetermined voltage and turning off the relay 40 when the voltage falls below a predetermined voltage at the time of key- And a nore-terminal short-circuiting key switch 80 for applying the power of the auxiliary battery 10 to the key-on (KEY ON) and battery terminal (B +) at the time of a key-on.
