Application of Shaped Magnetic Field in Resonance (SMFIR) Technology to Future Urban Transportation

Abstract

Transportation with electrified vehicles can reduce global dependence on fossil fuels and reduce the emission of green house gases. Recent developments have been focused on the development of electric vehicles, hybrid electric vehicles and fuel cell vehicles. However, the commercial deployment of electric vehicles has lagged behind due to technological issues in associated with the battery including: price, weight, volume, driving distance, and limited investment in charging infrastructure. Shaped magnetic field in resonance (SMFIR) technology enables electric vehicles to overcome these limitations by transferring electricity wirelessly from the road surface while vehicle is in motion. This work describes the innovative SMFIR technology used in the KAIST online electric vehicle (OLEV) project as well as its impact on the future of urban transportation. The system integration of the power supply into the OLEV and the vehicle system architecture is also discussed.
