Racing car with electric drive

Drive technology has an electric future – of this Fraunhofer research scientists are in no doubt. At the Sensor + Test measurement fair in Nuremberg from May 14 -16, they will use an electric racing car to present novel solutions for battery management and electronic sensor systems together with an industry partner.
The scientists are right on trend, as even FIA, the governing body for world motor sport, federation of the world’s leading motoring organizations and organizer of Formula 1, is planning a racing series for electric vehicles.

From 0 to 100 in 3.6 seconds – we’re not talking about the rapid acceleration of a Porsche Carrera or Ferrari Scaglietti, but of EVE, a racing car with a very quiet engine. EVE is powered by two electric motors, one for each rear wheel. With a maximum output of 60 kilowatts, they get the e-racer going at 4500 rotations per minute. The sprinter can reach a top speed of 140 km/h, and has a range of 22 km thanks to two lithium polymer batteries, with a combined capacity of 8 kWh. Electrical engineering students from the e-racing team at the Hochschule Esslingen University of Applied Sciences designed the 300 kg car as a voluntary project alongside their studies, and they have already competed in it at the international Formula Student Electric (FSE) race in Italy. From May 14-16, the racing car will be on show at the Sensor + Test measurement fair in Nuremberg at the joint Fraunhofer trade show booth (Hall 12, Booth 537). Scientists from the Fraunhofer Institute for Integrated Circuits IIS in Erlangen developed the entire electronic sensor system in close collaboration with Seuffer GmbH & Co.KG, an industry partner with whom the institute has been working for over 11 years. Seuffer GmbH & Co.KG is based in Calw in Baden-Württemberg, southern Germany, and sponsors the students of the E.Stall racing team.

“Electromobility as a topic is becoming ever more important. The racing car serves as a showcase for us to demonstrate novel sensor solutions as well as battery and energy management concepts,” says Klaus-Dieter Taschka, an engineer at Fraunhofer IIS. Besides wheels, brakes, damper unit, batteries and electric motors, EVE is equipped with numerous sensors. These include braking pressure, crash, temperature and acce-
leration sensors as well as sensors that monitor the accelerator and brake pedals, speed, steering angle, wheel speed and power. These last six functions could all be performed by HallinOne® sensors developed by Fraunhofer IIS, 3D magnetic-field sensors that are already a standard feature in washing machines, where they are used to determine the position and orientation of the drum.
