바이모달 트램의 직렬형 하이브리드 추진시스템 구성과 운전모드

초록

A bimodal tram is being developed to combine the flexibility of a bus with the punctuality of a train. The propulsion system of the bimodal tram is a series hybrid-type that uses a set of CNG engine generators and Li-polymer batteries. In this paper, the configuration of the series hybrid propulsion system for bimodal tram and three driving modes : hybrid, battery and engine modes are described.
