Abstract

Electric road systems (ERS) are technologies that allow to charge electric vehicles (EVs) while they are driving. A large scale implementation of ERS would allow to significantly reduce the installed battery capacity on board the vehicles, which consequently reduces their weight and cost. Due to geographical, practical and economic constraints the ERS is not expected to cover the full extension of the road being electrified. Instead, the ERS is expected to be implemented in sections which together would cover only a fraction of the overall length of the road (). If vehicles are to perform charge sustained trips while on the electrified road, there is a tradeoff between and the required charging power. In this context, this work presents... (More)

Electric road systems (ERS) are technologies that allow to charge electric vehicles (EVs) while they are driving. A large scale implementation of ERS would allow to significantly reduce the installed battery capacity on board the vehicles, which consequently reduces their weight and cost. Due to geographical, practical and economic constraints the ERS is not expected to cover the full extension of the road being electrified. Instead, the ERS is expected to be implemented in sections which together would cover only a fraction of the overall length of the road (). If vehicles are to perform charge sustained trips while on the electrified road, there is a tradeoff between and the required charging power. In this context, this work presents the implications of altering in the rating of the components of three alternative powertrains purposely designed to operate in conjunction with an ERS. The energy consumption and cost of the different powertrains is compared and conclusions on the effectiveness of the different configurations are drawn.
