Hamburg, May 2013 – The GreenTeam of the University of Stuttgart has been developing its electrically powered race car E0711-4 for more than a year. The group of 36 students will - like last year - enter its race car against other universities in the "Formula Student Electric" international design competition. The GreenTeam ranks as the best German team and 3rd in the world and holds the world record for acceleration (from 0-100 km/h in 2.68 sec.). Therefore the students have already set the bar high and want to continue to build on their past success with the E0711-4.
As a club, the GreenTeam is dependent on the support of sponsors. Pfannenberg is also represented this year along with Daimler, ZF, Bosch, SKF and others. "The sponsorship is in line with the Pfannenberg company motto 'Sharing Competence'. We are pleased to support new innovations and technologies, and the younger generation in the process, especially in the area of electric mobility," explained Andreas Pfannenberg, Managing Director of Pfannenberg.
The Race Car – Air Cooling in the Battery Housing
The air-cooled battery is the critical component of an electric race car. The air captured on one side of the monocoque by means of an air duct, drawn through the battery and released on the other side of the monocoque. Due to changing weather and environmental conditions, heavily fluctuating amounts of water and impurities from particles in the air must be taken into account in choosing an appropriate filter medium. A high air delivery rate must be achieved while continuously guaranteeing the electrical safety in the battery compartment.
The Solution – 4th Generation Filter Technology
Pfannenberg offers the optimal solution for this – the exhaust filter with patented fluted filter mats. The innovative technology of the Filterfans 4.0, which is normally used in the control units of machines, enables a high air output with system of protection IP 55 for a high degree of separation and a long service life. The filter mat absorbs harmful particles on its fan-shaped fins and the large surface area ensures separation of a significantly higher share of particles than conventional fleece filters. It protects the battery housing from penetrating rainwater and foreign objects during race and thereby guarantees the safety of the electronics.
