A battery discharge control method of the present invention is performed in a target voltage variable mode, when a hardware abnormality of a hardware discharging a battery in which a charge voltage is controlled to setting target voltage is recognized by an engine electronic control unit (ECU, 1), which deviates a battery discharge state which goes to turning off of an engine by controlling the charging voltage to resetting target voltage. The battery (10) charge due to an alternator (50) generation is performed in the battery discharge state due to battery (-) terminal chattering in the target variable mode, thereby controlling an engine system without turning off an engine.
본 발명의 배터리 방전제어방법은 설정목표전압으로 충전전압제어가 이루어지는 배터리를 방전시키는 하드웨어의 하드웨어 이상이 엔진 ECU(1)에 의해 인식되면, 재설정목표전압으로 충전전압제어가 이루어져 엔진 시동 꺼짐으로 진행되는 배터리 방전 상태를 벗어나는 목표전압가변모드로 수행되고, 상기 목표전압가변모드로 알터네이터(50) 발전에 의한 배터리(10) 충전이 배터리 (-)단자 채터링(chattering)에 기인한 배터리 방전 상태에서 이루어짐으로써 엔진 시동 꺼짐 없이 엔진 시스템을 제어하는 특징을 구현한다.
