Although the test and demo site is owned by Volvo Cars, Volvo Group (trucks) has full access to Hällered which is used as main test facility for new truck and bus products, and for research projects that require stringent confidential procedures.

In this test site Volvo has built a separate test track for conductive electrical road tests. Technical principle of conductive track is to facilitate “contact” between rails in the ground, connected to an upside pantograph, mounted onto the vehicle. The product name for this pantograph, at Volvo, is the so-called pick-up.

  • The electrical conductive test track at Hällered proving ground was built in summer of 2012, in joint cooperation with Alstom, the producer of APS technology (Aesthetic Power Supply), which has successfully been operating tram systems, in various cities in France.
  • The test track is 435m long and can be shut down specifically for electrical road tests without sweden3disturbing other traffic. The electrified part of the track is 275m and can today operate with DC voltage at standardized level of 750V DC.
  • Test track allows for acceleration and retardation so that vehicle can do tests at 80-100km/h when entering the electrified track.

The results of the technology evaluation from this test track will be provided to FABRIC, and if requested, test track and system can be demonstrated to FABRIC project team and partners. Preliminary tests are planned in this test site in order to give input to design and testing activities of the project, for example on expected power transfer efficiency verification, electro dynamic forces, electric circuit dynamics, overvoltage/under voltage dynamics. One of the most interesting opportunities will be to measure before any implementation electromagnetic emissions and electric field gradient within the ground which are highly relevant to ensure people safety. Additionally it will allow to benchmark at minimum cost the conductive technology implemented by VOLVO and examine the downscaling feasibility.
