Development of a non-contact rapid charging inductive power supply system for electric-driven vehicles

Non-contact rapid charging inductive power supply (IPS) system has been developed and tested as a charger for electric-driven vehicles (EdV). By using the developed 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 (35kg), thickness (33mm), and air gap length (100mm) during 30kW power transmissions.
