Economic and Environmental Feasibility, Architecture Optimization, and Grid Impact of Dynamic Charging of Electric Vehicles using Wireless Power Transfer
Integration of wireless power transfer (WPT) into roadways and vehicles represents a promising alternative to traditional transportation. In this study, the economic feasibility, environmental impact and infrastructure optimization of inmotion WPT in the U.S. is evaluated using dynamic vehicle models integrated with GPS stamped real world drive cycle data. Results show total vehicle level savings greater than the WPT EV purchase price with a societal level infrastructure payback time of 7.4 years at 25% fleet penetration for deployment in the U.S. Environmental results show the technology to be beneficial in terms of global warming impact and all criteria pollutants with the exception of SOx. Optimizing the technology for consumer satisfaction shows that up to 99% of light duty real world drive cycles are satisfied with a 25 mile on board electrical range utilizing 50 kW in motion WPT on high speed roadways. Additionally, overall grid impact is expected to be minimal if vehicle togrid power transfer is implemented.
