Abstract

A non-contact rapid charging inductive power supply (IPS) system has been developed and tested as a charger for electric-driven vehicles (EdV). By using this system, EdV charging can be carried out safely, easily, and in a short period. Optimizing the track and pick up design of the IPS based on finite-element electromagnetic field analyses achieved significant improvements in efficiency (92%), weight (35 kg), thickness (33 mm), and air gap length (100 mm) during 30 kW power transmission. Testing on public roads of an electric-micro bus equipped with the IPS is also detailed.
