Power Chapter WebEx: HIGH POWER AND DYNAMIC WIRELESS CHARGING OF ELECTRIC VEHICLES
HIGH POWER AND DYNAMIC WIRELESS CHARGING OF ELECTRIC VEHICLES
Dynamic charging or dynamic wireless power transfer (DWPT) can significantly alleviate range anxiety and concurrently reduce the on-board battery capacity required, there by reducing the weight, volume, and cost of EVs. Transferring power at higher levels (~ 200 kW) will lead to reduction of percentage of roadway or infrastructure that needs to be electrified thereby making the technology more viable. Existing wireless charging technology for LD vehicles is limited to 20 kW charge rates; this is not sufficient for most dynamic DWPT applications, especially at higher vehicle speeds. In some applications, five or more 20 kW systems have been used in parallel to achieve higher power levels. Although this may be a reasonable approach for MD and HD vehicles, it is not practical for light-duty passenger vehicles where space is limited and fitting more than one or two coil assemblies on the vehicle is infeasible. This seminar focusses on the challenges and ORNL’s approach to overcome them to enable a practicable 200 kW dynamic wireless EV charging system.

Biography:
Veda Prakash Galigekere (Senior Member, IEEE) was born in Bengaluru, India, in 1982. He received the B.E. degree in electrical engineering from Visvesvaraya Technological University, Bengaluru, India, in 2004, and the M.S. and Ph.D. degrees in electrical engineering from Wright State University, Dayton, OH, USA, in 2007 and 2012, respectively. In 2008 and 2012, he was an Intern with the General Electric Global Research Center, Bengaluru, India. From 2012 to 2016, he was with Lear Corporation, Southfield, MI, USA. He is currently a Research and Development Staff Member and Group Leader of Electric Drives Research Group with Oak Ridge National Laboratory, Oak Ridge, TN, USA. His research interests include high-power wireless power transfer, high-frequency resonant converters, impedance source converters, and small-signal modeling and control of pulsewidth modulation dc–dc converters. Dr. Galigekere was a Guest Associate Editor of the IEEE Transactions on Power Electronics. He is currently an Associate Editor of the IEEE Transactions on Industry Applications.
