Battery electric vehicles’ contribution to the viability of charging from below electric road system based on individual driving patterns

This study uses detailed driving patterns to model the benefits of implementing an ERS in Sweden with charging from below technology that is usable by passenger BEVs. This technology would increase the utilization of ERS infrastructure and possibly lead to significant cost savings in BEVs by enabling smaller batteries. Results show that the required average battery capacity could drop up to 76 % and the expected savings of using smaller batteries range between 0.17 -6.5 M€/ERS km for a total of 2900-9300 M€. The economic net benefit is heavily dependent on the percentage of cars switching to BEV and ERS placement.
