Hydrogen-Powered Tramcar Energy Management System

Abstract

This research focuses on the development of an Energy Management System (EMS) for a hybrid power tramcar. The proposed system integrates various components, including a drawing bus, super capacitor, battery, fuel cell, and controller. The super capacitor is connected to the traction bus through the first two-way DC/DC converters, while the battery is connected through the second two-way DC/DC converters. The fuel cell is connected to the traction bus through a control module, which includes a diode, first unidirectional DC/DC converters, and a switch. The switch and the first unidirectional DC/DC converters are connected in parallel, with the switch linking the first common node of the converters to the traction bus and the second common node to the diode. The diode is then connected to the fuel cell.
