Efficiency evaluation of a conductive Electric Road System with respect to traffic characteristics

Abstract

Electric Road Systems (ERS) are effective charging infrastructures that allows electric vehicles to receive energy while driving. This energy is used both to propel the vehicle and to charge the battery. Sufficient deployment of ERS implies that charging opportunities become greatly increased, allowing for electric vehicles to have smaller batteries and easing some of the problems associated with static fast-charging such as queues and need for large available areas. In this paper a simulation model for a conductive electric road is introduced and experimentally validated on a conductive electric road demonstrator. Two main ERS deployment cases with corresponding traffic flows are simulated: urban and rural. The results show that the... (More)

Electric Road Systems (ERS) are effective charging infrastructures that allows electric vehicles to receive energy while driving. This energy is used both to propel the vehicle and to charge the battery. Sufficient deployment of ERS implies that charging opportunities become greatly increased, allowing for electric vehicles to have smaller batteries and easing some of the problems associated with static fast-charging such as queues and need for large available areas. In this paper a simulation model for a conductive electric road is introduced and experimentally validated on a conductive electric road demonstrator. Two main ERS deployment cases with corresponding traffic flows are simulated: urban and rural. The results show that the urban simulation case has an efficiency of 96.5% and the rural simulation case has an efficiency of 95.7%. For the urban simulation case the impact of traffic intensity and traffic congestion on the ratio of semiconductor losses and resistive losses is evaluated. This evaluation shows that for this type of ERS design semiconductor losses should be considered in future ERS deployments in urban environment where traffic congestion and queues occur. Finally, a system efficiency comparison between the urban and rural simulation cases and a conventional static charger shows that an ERS can provide equivalent or even greater system efficiency than that of a conventional static charger depending on ERS application, deployment and design.
