Short Biography

Sarr Cheikh Tidiane was born in Senegal in March 1989. He received an M.S. degree in electrical engineering from the University Cheikh Anta Diop, Dakar, Senegal, in 2015 and an M.S. degree from University of Le Havre, Le Havre, France, in 2017. He is currently a PhD student with the Groupe de Recherche en Electrotechnique et Automatique du Havre (GREAH) Laboratory, University of Le Havre. Since 2017, he has been working on power electronics, dc distribution systems, and multi-physical characterization of supercapacitors and batteries dedicated to multi-source systems.

In this paper, a hybrid electric power supply system for an electric vehicle (EV) is investigated. The study aims to reduce electric stress on the main energy source (fuel cell) and boost energetic performances using energy sources with high specific power (supercapacitors, batteries) for rapid traction chain solicitations such as accelerations, decelerations, and braking operations. The multisource EV power supply system contains a fuel cell stack, a lithium batteries module, and a supercapacitors (Sc) pack. In order to emulate the EV energy demand (wheels, weight, external forces, etc.), a bidirectional load based on a reversible current DC-DC converter was used. Fuel cell (Fc) stack was interfaced by an interleaved boost converter. Batteries and the Sc pack were coupled to the DC point of coupling via buck/boost converters. Paper contribution was firstly concentrated on the distribution of energy and power between onboard energy sources in consonance with their dynamic characteristics (time response). Second contribution was based on a new Sc model, which takes into consideration the temperature and the DC current ripples frequency until 1000 Hz. Energy management strategy (EMS) was evaluated by simulations and reduced scale experimental tests. The used driving cycle was the US Federal Test Procedure known as FTP-75.
