Simulation platform of electric road systems – a Swedish case study

Electric Road System (ERS) is a key technology to achieve the electrification in the long haulage application due
to battery limitations. Before deciding on large scale investments in ERS, it is important to analyse what road
segments that benefit the most of such a system. A model of a hybrid powertrain configured as a long haulage
truck is developed with the possibility for dynamic charging. Simulations are performed to analyse a region in
Sweden where an ERS demonstration is built, to investigate how different ERS configurations affect the energy
consumption of the vehicle. It is found that the fuel consumption is decreased by 66% when the full road is
electrified, and the travel time decreased by 7%, compared to a conventional vehicle. Simulations also indicate
that it is beneficial to only electrify parts of the road and using the battery in the vehicle as energy buffer.
Furthermore, different data sources for road elevation and vehicle speed data have been evaluated. It is shown that
Google data and speed limit data can be useful for initial studies, but measured vehicle speed data and laser scanned
data increase the accuracy in the simulations.
