Energy management of multi-sources vehicles is a complex task. The higher the number of sources becomes, the higher the complexity is. Moreover, the energy management methods have to face real-time issues. As a consequence, it is important to find some testing procedures to assess the developed methods, in real-time conditions before implementation on the vehicle. In this paper, a Power Hardware-In-The-Loop simulation is implemented for a Fuel Cell - battery - Supercapacitors vehicle. The platform enables to test some Energy Management Strategies in real-time conditions.
