Ensuring Thermal and Structural Robustness of Pavement Embedded Wireless Charging Pads – Testing from Materials through to Full-scale

Simon Bickerton, Professor of Mechanical Engineering and Tom Allen, Senior Lecturer in Mechanical Engineering, University of Auckland

Wireless systems for stationary and dynamic charging of electric vehicles must be integrated within, and survive the harsh thermal and structural conditions created inside pavements. In this presentation, Professor Simon Bickerton and Dr. Tom Allen discussed research at the University of Auckland, New Zealand, that focuses on systems for flexible asphalt based pavements. Working from an understanding of the properties and failure behaviour of key components such as ferrite and litz wire, the discussion included multi-physics models that are being developed for structural and thermal design of inductive power transfer (IPT) pads embedded within asphalt.
