Today we are launching our new website www.sdu-vikings.dk! hop in and check it out!

Due to COVID-19 the workshop has unfortunately been closed since march. Even though we have been able to design our parts during this time, we have been set back in our production. Now the workshop has finally been reopened and we are very excited to build and test Viking X! (Within the COVID-19 restrictions of SDU) ... See more

I forbindelse med 200 års jubilæet af H. C. Ørsteds opdagelse af elektromagnetismen, står vi på Torvet i Rosengårdscenteret i dag og de næste to lørdage. Kom forbi og hør om hvad vi bruger elektromagnetisme til i vores elektriske racerbil. ... See more

The accumulator for Viking X stores the energy needed to drive the car. It consists of 140 cells in series for a total maximum voltage of 588V. The cells used are pouch cells from Melasta. The total energy of the accumulator is 6.5 kWh.
The electronics in the accumulator is all about safety. This is achieved with our self-developed Accumulator Management System. The voltage and the temperature of the cells are monitored in order to ensure safe operation of the accumulator. The AMS is not only used during driving, but is also vital to charge the accumulator safely.
Many of the components, including connectors, passives, transformers and DC/DC converters are from Würth Elektronik eiSos Group.

Another part of the safety system in the accumulator is the Insulation Monitoring Device from Bender GmbH & Co. KG. This device monitors the insulation between the high-voltage system and the chassis of the car.

In order to ensure safe operation, all these safety measures have the possibility to completely isolate the accumulator from the car. ... See more

Viking X chassis design.
The chassis on Viking X is made from Docol R8 tubes and Docol 800 DP supplied by SSAB
The tubes were cut on a 3d profile laser cutter at Quicktube.
All the brackets including our welding jig were laser cut at AluSteel.
Laser cutting of tubes and plates eases the welding process substantially, since it is almost like assemblying a 3d puzzle.
The weight of the chassis including brackets and powder coat is 33,5 kg. ... See more
