Design of Safe Wireless Power Transfer Systems for Electric Vehicles

摘要

Wireless charging of electric vehicles is convenient but in order to make it safe the exposure of humans to electromagnetic fields must be below acceptable limits. We have designed a prototype system that transmits 3 kW with an efficiency of 85% where the magnetic fields around and inside the vehicle are below the EU council recommendation of $6.25mutext{T}$ at 85 kHz.
