Inductive Power Transfer Charging Infrastructure for Electric Vehicles: A New Zealand Case Study

Inductive Power Transfer (IPT) is one of the fastest evolving technologies in the development of Electric Vehicles (EVs). Dynamic charging of EVs involves charging of the vehicle without contact while in motion without the need to stop the vehicle over the energized section. Advantages over traditional systems like the elimination of recharging downtime and reducing the battery range anxiety for extended travel distance, make this technology highly promising for practical roadway implementation. This paper provides first steps towards the development of a mathematical model for the purposes of evaluating the benefits and costs to transportation infrastructure by comparing the optimal battery size and position of the electric vehicle charging section. The model is used to simulate a potential electric bus route in New Zealand for installation of the technology. The primary objective of this research is to provide a range of cost estimates of potential dynamic IPT system implementation, its feasibility and to demonstrate IPT roadways as a viable investment opportunity for potential investors thereby preparing it for possible commercialization.
