Study on the Energy Demand of Vehicle Propulsion to Minimize Hydrogen Consumption: A Case Study for an Ultra-Energy Efficient Fuel Cell EV in Predefined Driving Conditions
Year: 2026
Type: conference-paper
Abstract: Nowadays, the automotive industry is primarily driven by the CO 2 policy that targets net zero carbon emissions by 2035 from passenger cars and commercial vehicles.The main path to achieve this goal is the implementation of electric powertrains with the energy stored in batteries, as the case for battery electric vehicles (BEV).However, this technology still faces some difficulties in terms of energy density, overall weight, charging time, and vehicle autonomy.From the other point of view, fuel cell electric vehicles (FCEV) offer the same advantages as BEV in terms of CO 2 reduction, providing better autonomy and lower refueling time.The energy demand by the electric powertrain strongly depends on the vehicle driving conditions as it directly affects energy consumption.In that context, the article aims to study the electrical energy demand of an ultra-energy efficient vehicle intended for a Shell eco-marathon competition in order to minimize hydrogen consumption.The study was carried out over a single lap on the racing track in Nogaro, France while applying the race rules from the competition in 2023.It includes a numerical evaluation of the vehicle resistance forces in different driving strategies and experimental validation on the propulsion test bench.
