The SolarWorld No. 1 is a solar-powered road vehicle from the Bochum University of Applied Sciences , which took part in the World Solar Challenge in 2007 and in the Global Green Challenge in 2009 . The successor model of this vehicle is the BOcruiser , the previous model is the HansGo! .
The three-wheeled SolarWorld No. 1, which reaches a top speed of over 120 km / h, is powered by a wheel hub motor in the front wheel with a maximum output of 1.4 kW. The empty vehicle weight is around 230 kg, of which the batteries take up around 25 kg. The solar cells used are gallium arsenide solar cells with an efficiency of 29%. The output of the 6 m² solar cells on the roof is 1800 watts.
Accumulators
The accumulators are 532 cells of the type UR18650-F lithium-ion accumulators. Which were obtained from the Sanyo company . For the World Solar Challenge 2007 a battery weight of 25 kg was available. A stored amount of energy of 4821 Wh at a nominal voltage of 107 V was achieved.
Solar cells
The solar cells are gallium arsenide solar cells. The maximum efficiency is 29%. In order to achieve this level of efficiency, MPPTs (Maximum Power Point Tracker) from Brusa are used in the vehicle. The total electrical power of the array is approx. 1800 W.
engine
The motor is a permanent magnet synchronous machine developed at the Bochum University of Applied Sciences. The motor has a nominal output of 1.4 kW and a maximum output of 4.2 kW. The maximum speed of the vehicle is 120 km / h.
World Solar Challenge
The vehicle was specially built for the World Solar Challenge 2007 (WSC 2007). In the race across the Australian continent (3000 km from Darwin to Adelaide) the vehicle took 4th place. It also received the Design Award for its outstanding and innovative shape. A report about the WSC 2007 and an interview with Prof. Friedbert Pautzke (professor for electromobility at Bochum University) was broadcast on November 3, 2007 in the WDR program "Lokalzeit Ruhr".
The team
During the race, the team consisted of around 30 students, who were also responsible for building the vehicle. In the team, individual working groups dealt with the electrics, mechanics, strategy and organization of the competition.
Awards
In addition to the aforementioned design award, the Bochum University of Applied Sciences, as the developer and location of SolarWorld No.1 , was named "Selected Location" on April 16, 2008 by the Germany - Land of Ideas initiative .
