Benefits of Electric Road System with charging from below technology to battery electric vehicles
Other conference contribution, 2021

This study uses GPS-logged movement patterns of 412 private conventional cars in Sweden to model the potential impacts and benefits of implementing an Electric Road System (ERS) that is designed to be usable also to passenger Battery Electric Vehicles (BEVs). The study inspects the possibility of eliminating stationary charging stations and allowing smaller batteries in BEVs and its economic benefit. The study examines different ERS placement scenarios, charging options and BEV shares. The results show that an ERS makes possible a drastic reduction in the required battery capacities to complete all driving. With only charging at home, the mean reduction in battery capacity is 75%, or to about 14 kWh. An average battery capacity of 87 kWh could eliminate all stationary charging. In Sweden, with an ERS net economic benefits of 29-45 billion € are expected from reduced battery capacities alone, depending on the stationary charging pattern, percentage of cars switching to BEV, ERS placement and ERS charging rate.
