본 발명의 배터리 과 방전 방어방법은 하이브리드 차량(100)의 등판 로 주행 중 엔진 클러치(400)의 슬립(Slip) 시 배터리(20-1)의 SOC(State Of Charge)의 충전임계값(Threshold)이 고려되고, 등판 로와 슬립(Slip)에서 충전임계값(Threshold) 보다 작은 SOC인 경우 엔진(200)의 토크 리저브 제어로 배터리(20-1)의 방전이 방어되도록 컨트롤러(1)로 제어되고, 특히 엔진클러치(400)의 슬립(Slip)이 유발되는 가다 서다를 반복하는 산악지형을 운행하는 하이브리드 차량(100)에 적용된 상기 컨트롤러(1)는 배터리(20-1)의 SOC를 항상 일정량 이상으로 낮아지지 않도록 토크 리저브 제어로 방어함으로써 하이브리드 차량(100)이 주행 불가로 빠지게 않는 특징을 구현한다.
A method for preventing over discharge of a battery includes steps of: detecting a gradient of a road on which a vehicle is running by a controller, when a battery is discharged under a state that an engine of the running vehicle is operated, detecting a clutch driving state of an engine clutch, which connects or disconnects the engine and an electric motor, after detecting the road gradient, detecting a SOC (State of Charge) of the battery after detecting the clutch driving state of the engine clutch, and carrying out a torque reserve control allowing more torque to be reserved in the engine, using a combination of the road gradient, the clutch driving state, and the battery SOC, such that the battery SOC is not lowered below a certain amount.
