This paper describes a powertrain test bed platform for Fuel Cell Hybrid Electric Vehicles (FCHEVs) that can be used to evaluate Energy Management Strategies (EMS). The Hardware-in-the-loop (HIL) simulation platform comprises two parts: 1) the simulation of the vehicle's electric powertrain, 2) the monitoring and control of the vehicle through the use of an ad hoc data administration and communication system that uses CAN Bus. Evaluation of the test platform is performed using an urban driving cycle, which also allows the illustration of the starting and emergency protocols.
