Simultaneous Wireless Power/Data Transfer for Electric Vehicle Charging

Wireless Transfer of Electric Power

In this dissertation, I describe the design and construction of a system which can transfer electric power wirelessly. This is accomplished using inductive, near-field, non-radiative coupling between self-resonant copper helices. In our first experiment, we transfered 60W of power over a distance of 2m with 45% efficiency. In our second experiment, we designed a system which can transfer power ...

Dynamic Wireless Power Transfer System for Electric Vehicle to Simplify Ground Facilities - Power Control Based on Vehicle-side Information -

Electric vehicles (EVs) have environmental advantages and the capacity for advanced motion control. However, EVs need to be charged frequently due to their limited mileage per charge. A dynamic wireless power transfer (WPT) system for EVs can extend their cruising distance and reduce the size of their energy storage system. However, when being applied to rugged roadways over long distances, it ...
