Operational requirements for dynamic wireless power transfer systems for electric vehicles

Abstract

This paper presents initial findings from a study to identify road operator and power distribution system operator operational requirements for dynamic wireless power transfer systems for electric vehicles. A number of solutions are currently being developed around the world but in order for them to be effective and desirable in the transport domain, they must be able to meet the key operational requirements. The results presented in this paper aim to identify key requirements, assess to what degree they should be met and discuss possible implications of these requirements on the design of dynamic wireless power transfer systems for EVs. Requirements such as misalignment tolerances between primary and secondary coils due to driver behaviour, power transfer section segmentation and separation, possible impacts on road network performance, power and energy supply capability, and implications of peak power demand profiles under varying traffic conditions are considered and addressed.
