Summary The target of Shell Eco‐marathon competition of vehicle is to drive a fixed distance with the lowest quantity of fuel. To win the competition, the fuel cell‐powered propulsion system needs to be ultra efficient since the fuel cell system and transmission system are the key effects on the performance of the fuel cell‐powered propulsion system. In this study, a high‐efficiency fuel cell propulsion system has been designed and integrated in a prototype vehicle to participate the Shell Eco‐marathon Asia 2018 race. To achieve that, the vehicle dynamic is modeled to make the selection of the key components, and some experiments have been conducted to obtain the properly vehicle driving strategy. Based on the results of vehicle dynamic analysis, a high specific power proton‐exchange membrane fuel cell (PEMFC) stack with 1000 W and a high‐performance direct current (DC) brushless motor (1000 W) are selected to build the propulsion system of the Shell Eco‐marathon vehicle. Based on the experimental result, the racing time (1300‐1440 seconds) and varied range of racing speed (23‐27 km/h) are selected as the driving strategy. Finally, the efficiency of the fuel cell‐powered vehicle is analyzed. In the race at the year of 2018, the designed vehicle won the first place.

“…In contrast to many ICV races, the goal of most of the EV races is not to be the fastest but to minimize the energy consumption of the vehicles, that is, the winner is the most energy efficient vehicle. Nowadays, such races take place on the five continents and so involve worldwide universities, research centers and enterprises [1][2][3][4][5]. For the engineering schools, there are a big number of topics which have technological development and/or research aspects which can make the design and manufacturing of an Electric Race Vehicle (ERV) to be of great interest for professors and students [6].…”

This paper describes a project based learning program carried out in the E.T.S.I.I. of the University of Malaga, Spain, whose main objective is the organization of a team for the development of experimental electric racing vehicles and their evaluation in competitive races. It is shown the work done during the first two years of the project, highlighting the most important aspects of the experience: the training focused on senior students (capstone courses), the training focused on freshmen (cornerstone courses) and the university-industry collaboration for the manufacture of the prototypes and equipment designed.

The article presents a method for optimizing driving strategies aimed at minimizing energy consumption while driving. The method was developed for the needs of an electric powered racing vehicle built for the purposes of the Shell Eco-marathon (SEM), the most famous and largest race of energy efficient vehicles. Model-based optimization was used to determine the driving strategy. The numerical model was elaborated in Simulink environment, which includes both the electric vehicle model and the environment, i.e., the race track as well as the vehicle environment and the atmospheric conditions. The vehicle model itself includes vehicle dynamic model, numerical model describing issues concerning resistance of rolling tire, resistance of the propulsion system, aerodynamic phenomena, model of the electric motor, and control system. For the purpose of identifying design and functional features of individual subassemblies and components, numerical and stand tests were carried out. The model itself was tested on the research tracks to tune the model and determine the calculation parameters. The evolutionary algorithms, which are available in the MATLAB Global Optimization Toolbox, were used for optimization. In the race conditions, the model was verified during SEM races in Rotterdam where the race vehicle scored the result consistent with the results of simulation calculations. In the following years, the experience gathered by the team gave us the vice Championship in the SEM 2016 in London.
