Shell Eco-marathon Europe People's Choice Contest
School: Engineering and Technology Institute, Paris-West University (France)
Car Name: EcoCar8ES (Battery Electric Prototype category)
What is special about your car? EcoCar8ES is a supermileage prototype, all battery category, with a solar module. Two front wheels steering. Rear power train using a cheap RC hobby out-runner brushless (PM-BLDC). Very aero-dynamical body using NACA profile. Composite material. Yellow color.
Why is fuel efficiency important to your team? One major of our Education Institution is "Thermal and Energy Study." To complete and illustrate the courses it is very important that students could have a realistic project for applying the theoretical approach. Simulation by software is typically used to optimize the prototype car, year after year. Students are also building a testing bench with the objective to simulate real conditions of any track. Recorded data are the source for a good optimization of the race strategy. Students pilots are also very motivated to drive with the objective to win the SEM international challenge.
Who or what inspired you on the way to Eco-marathon? IUT-VA team was created in 1985 to compete in Shell Eco-marathon in France. The first EcoCars were using Internal Combustion Engines (ICE). In 2009 the team decided to change and adopted the electric motor. Studies are made to use micro-controller platforms based on modern technology. In this domain, students are developing hardware and software.
** Brushless controller using Field Oriented Computing algorithms.
** Pilot display on Android device, Bluetooth linked.
** Data logging on SD memory card.
** Telemetry toward the paddock using 2.4 GHz modules.
** Battery Management System and temperature controllers.
Working Toward Smarter Cities
From better mass transit to a stronger mix of renewable energy, what is the most important thing we can do to make cities smarter when it comes to energy use?
Istanbul, the only city in the world that spans two continents, is a perfect setting for a close look at the energy and sustainability challenges of our increasingly urban planet.
