The BOcruiser is a solar-powered electric vehicle from Bochum University . BOcruiser is the third vehicle from Bochum University and took part in the Global Green Challenge 2009 (GGC), a competition that took place parallel to the World Solar Challenge in 2009 . The successor model of this vehicle is the SolarWorld GT , the previous model is SolarWorld No. 1 .

mass and weight

The vehicle is about 4000 mm long, 1600 mm wide and 1400 mm high. The unladen weight of the vehicle is around 280 kg.

Accumulators

The accumulators are 532 cells of lithium-ion accumulators of the type UR18650-F, which were obtained from the company Sanyo . For the GGC 2009, a battery weight of 25 kg was available. A stored amount of energy of 4821 Wh at a nominal voltage of 103.6 V was achieved.

Solar cells

The solar cells are monocrystalline solar cells. The maximum efficiency of a cell is 21.5%. In order to achieve this level of efficiency, MPPTs (Maximum Power Point Tracker) from Drivetek are used in the vehicle. The total electrical output of the 6 m² array on the roof is approx. 1250 W.

Engines

The two motors, which are designed as wheel hub motors in the front wheels, are permanent-magnet synchronous machines developed at the Bochum University of Applied Sciences . The motors have a nominal output of 1.4 kW each and a maximum output of 4.2 kW each. The maximum speed of the vehicle is 115 km / h.

Global Green Challenge

The vehicle was specially built for the Global Green Challenge 2009 (GGC 2009). In the race across the Australian continent (3000 km from Darwin to Adelaide) the vehicle took 12th place. In addition, the BOcruiser, like its predecessor - the SolarWorld No. 1 - the Design Award for its revolutionary and innovative shape. The development of the BOcruiser prompted the organizers of the World Solar Challenge to set up their own competition class for solar vehicles for the first time in 2013, the “Cruiser Class”. The aim of the vehicles that are allowed to start in this class is to obtain road approval in their country of origin, i.e. to develop vehicles that are suitable for everyday use.

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.
