Abstract

본 발명은 미등의 점등상태나 기타 전장품을 “온” 상태로 운전자가 차량을 주차시키는 경우 일정시간 내에 전원을 차단하여 배터리가 방전되는 것을 방지하도록 한 차량의 방전방지 회로 및 방법에 관할 것으로, 종래에는 차량을 장시간 주차시키거나 급하게 주차시키는 경우 미처 미등을 소등하지 않았거나 기타 전장품의 스위치를 끄지 않고 장시간 하차할 때 상기 미등과 전장품으로 배터리의 전원이 지속적으로 공급되어 배터리가 방전되는 문제점이 있었던바, 본 발명은 얼터네이터(11)의 출력이 정지되고 운전자가 승차중인 경우 플럭을 “오프”시키며, 얼터네이터(11)의 출력이 정지되고 운전자가 하차한 경우 플럭을 “온” 시키고, 타이머를 작동시킨 차량의 현재 상태 감지단계(S₁₁-S₁₇)와; 상기의 플럭 “온” 상태가 셋팅된 시간까지 계속 진행되는가를 판단하는 전원 차단 준비단계(S₁₈)와; 전원차단 준비단계의 셋팅시간이 지나면 전원차단 릴레이(13)를 “오프” 시켜 릴레이 스위치(15)를 단락시키는 배터리 방전 방지단계(S₁₉-S₂₁)로 구성하여 운전자의 실수로 미등을 점등한 상태 또는 전장품을 켠 상태에서 장시간 하차하는 경우 셋팅된 일정 시간이 지나면 미등과 전장품에 공급되는 전원을 차단하여 배터리의 방전을 방지하는 것임.The present invention relates to a discharge preventing circuit and a method of preventing a vehicle from discharging a battery by shutting off power within a predetermined time when a driver parks the vehicle in a state where a tail light is turned on or other electric equipment, and the electronic device is “on”. There is a problem in that when the vehicle is parked for a long time or is parked in a hurry, the tail light does not turn off or when the vehicle is discontinued for a long time without switching off the electric equipment, the battery is continuously supplied to the tail light and the electronic device to discharge the battery. In the present invention, when the output of the alternator 11 is stopped and the driver is riding, the flocks are “off”. When the output of the alternator 11 is stopped and the driver gets off, the flocks are “on” and the timer is operated. Detecting the current state of the vehicle (S ₁₁ -S ₁₇ ); A power cutoff preparation step (S ₁₈ ) for determining whether the above-mentioned flop “on” state continues until a set time; After the setting time of the power cutoff preparation phase, the power cutoff relay 13 is “off” and the battery discharge prevention step (S ₁₉ -S ₂₁ ) is made to short-circuit the relay switch 15. In case of getting off for a long time in the state or the electric equipment is turned on, it is to prevent the discharge of battery by cutting off the power supply to the tail light and the electric equipment after a set time.
