Experimental car "Schluckspecht" from the University of Applied Sciences Offenburg is breaching the Japanese course world record of battery driven cars
The team "Schluckspecht" drove 1631.5 km with his battery driven car without recharging the batteries.
The run took place at the Bosch test track in Boxberg, Germany. 4 drivers changed the seat in the Schluckspecht E continuously over the entire run time of 36 hours and 12 minutes. For complete documentation of the run an extra car where a camera was mounted followed the Schluckspecht E at any time. The TÜV Süd observed the attempt additional.The weather conditions on the excellent track with a length of 2.945 km were changeable/rainy.
This is another important achievement after the successful participation at the South- African Solar Challenge 2010 where the team covered a distance of 626.6 kilometers on public roads.
The successful record is the result of a car with a consequent light weight construction. Therefore the car got a new vehicle body called Bow- String- Structure (BSS). That is the principle of a bowstring bridge where the forces are distributed over the bows. The Schluckspecht E uses this principle by hanging the masses like the batteries and the passenger on two crossed bow tubes. With this light weight construction the single- seated car has an overall weight of 320 kg.
Another important point is the air resistance. The car body shell was developed by a design study of Mrs. Sunmin Lee (HS Pforzheim). The car body shell of the Schluckspecht E features a very low air resistance, because there is no place for an engine or transmission needed.
The car is driven by two self- developed wheel hub motors, which get their energy from 14 lithium-cobalt- battery- packs. A self- built battery- management- system monitors the safe operation of the packs.
With all of these developments the actual world record, positioned from the team of the Japan Electric Vehicle Club, of 1003 km was overbid with a distance of 1631.5 km. This was reached with a battery capacity of only 23 kWh and an average speed of 45 km/h (in comparison: the battery capacity of the Japanese team was 50 kWh and the average speed 40 km/h).
"This achievement is an indication of the high level of teaching and research and development at the University of Applied Sciences Offenburg", Professor Dr. Ulrich Hochberg explained proudly.
