The present invention relates to a mild hybrid system for a vehicle. An objective of the present invention is to provide a mild hybrid system for a vehicle which integrates two batteries of different types arranged in a conventional system into one to reduce an overall system size, and improve power conversion efficiency of a DC-DC converter. According to the present invention, the mild hybrid system for a vehicle can reduce loss by energy conversion of a DC-DC converter by reducing an operating zone of the DC-DC converter in comparison to a conventional system, and increase overall system efficiency by charging an integrated battery with electric energy generated by power regeneration during a generation operation of an MHSG.

    본 발명은 차량용 마일드 하이브리드 시스템에 관한 것으로, 기존 시스템에 구비되는 서로 다른 타입의 2가지 배터리를 하나로 통합 구성하여 시스템 전체 사이즈를 축소하는 동시에, DC-DC 컨버터의 전력 변환 효율을 향상할 수 있는 차량용 마일드 하이브리드 시스템을 제공하는데 그 목적이 있다. 본 발명에 따른 차량용 마일드 하이브리드 시스템에 의하면, 기존 시스템 대비 DC-DC 컨버터의 동작 구간이 줄어듦에 따라 DC-DC 컨버터의 에너지 변환에 따른 손실을 저감할 수 있으며, MHSG의 발전 동작 시 전력 회생의 의해 생성되는 전기에너지가 모두 통합 배터리에 충전됨으로써 시스템 전체 효율이 증가되는 효과를 얻을 수 있다.
