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.
