The present invention relates to an energy management system for an electric tram driven by a dual proton-exchange membrane fuel cell (PEMFC) and a battery and, more particularly, to an energy management system for an electric tram driven by a PEMFC and a battery, which uses the dual PEMFC and the battery as energy sources, and generates a pulse-width modulation (PWM) signal to control a first DC/DC converter, a second DC/DC converter, and a third DC/DC converter installed at the rear ends of the dual PEMFC and the battery to boost an output voltage. The energy management system comprises: an upper layer (100) which assigns power required for an electric tram to the dual PEMFC and the battery; a middle layer (200) which distributes the reference power of the dual PEMFC to PEMFC 1 and PEMFC 2; and a lower layer (300) which generates a PWM signal. Therefore, a charged state of the battery can be ensured within an allowable range.

    본 발명은 듀얼 PEMFC(Proton-exchange membrane fuel cell) 및 배터리에 의해 구동되는 전기 트램의 에너지 관리 시스템에 관한 것으로서, 특히 듀얼 PEMFC와 배터리를 에너지원으로 하고, 상기 듀얼 PEMFC 및 배터리의 후단에 각각 설치되어 출력전압을 승압시키는 제1 DC/DC 컨버터, 제2 DC/DC 컨버터 및 제3 DC/DC 컨버터를 제어하는 PWM(pulse-width modulation) 신호를 생성하는, 듀얼 PEMFC 및 배터리에 의해 구동되는 전기 트램의 에너지 관리 시스템에 관한 것이다.
