Claims (4)
- 시동 온과 함께 차량의 기동시 배터리 내부저항을 측정하는 제1단계와;배터리 내부저항 측정 결과, 배터리 내부저항이 기동 및 사용 가능한 배터리 내부저항 수치인 제1기준저항보다 크면, 회생제동시 발전 출력을 고정시키는 제2단계와;고정된 발전 출력으로 회생제동이 이루어지는 제3단계와;회생제동에 따른 배터리 충전이 이루어짐과 함께 배터리 충전전류가 기준충전전류와 비교하여 크면, 배터리 정전압 충전 제어가 수행되는 제4단계와;정전압 충전이 진행된 후, SOC를 초기화시키는 제5단계;를 포함하는 것을 특징으로 하는 하이브리드 차량의 배터리 성능 보상 및 SOC 초기화 방법.
- 청구항 1에 있어서, 상기 제2단계는 배터리 내부저항을 측정 결과, 배터리 내부저항이 기동 및 사용 불가한 배터리 내부저항 수치인 제2기준저항보다 크면, 배터리 교체를 경고하는 단계를 더 포함하는 것을 특징으로 하는 하이브리드 차량의 배터리 성능 보상 및 SOC 초기화 방법.
- 청구항 1에 있어서, 상기 제4단계는 회생제동에 따른 배터리 충전이 이루어짐과 함께 배터리 충전전류가 기준충전전류와 비교하여 더 작으면, 배터리 교체를 경고하는 단계를 더 포함하는 것을 특징으로 하는 하이브리드 차량의 배터리 성능 보상 및 SOC 초기화 방법.
- 청구항 1에 있어서, 상기 SOC를 초기화시키는 단계는 정전압 충전시, 배터리 충전 전류를 측정하여 연산 SOC의 초기화를 설정하는 배터리 충전 전류가 수입됨을 판단하는 과정을 통하여, 일정 전류가 수입될 때 수렴전류에 의한 SOC를 추정하여 이 추정값을 SOC 초기화값으로 설정하여 SOC를 초기화시키는 것으로 진행되는 것을 특징으로 하는 하이브리드 차량의 배터리 성능 보상 및 SOC 초기화 방법.
