Charging strategies – implications on the interaction between an electrified road infrastructure and the stationary electricity system

This study uses a vehicle model together with detailed traffic data of the European route 39 in western Norway to estimate how the electricity demand for an electric road system varies with time and location. The aim is to better understand the impact of an electric road system on the stationary electricity system. The results show that the electricity demand for an E39 electric road system is comparable to a larger industry, potentially increasing the peak power demand in the regional electricity system with only a few percent. Yet, if all main Norwegian roads are electrified, or if vehicles can also charge their batteries while driving, there will be a significant (>10%) addition of electricity demand to the current load
