2021 IEEE Workshop on Emerging Technologies: Wireless Power (WoW)

June 1 – 4, 2021, San Diego, CA, USA

Shaping the Future of RF Wireless Power Transmission

Cesar Johnston

Chief Operating Officer and Executive Vice President of Engineering, Energous

Abstract: The proliferation of handheld devices across our daily lives means we are often tethered via wires to power outlets. New, inductive-based technologies are enabling us to remove wires from the equation and eliminate the frustration of having to periodically plug in our gadgets. But, as wireless charging evolves and customers’ requirements increase, a second-generation technology is needed to support multiple device charging, freedom of placement, and most important wireless power delivery at-a-distance from the wireless charger—not just at contact. Cesar Johnston, COO and EVP of Engineering at Energous and a leading authority on wireless power, will share his vision for the future of Wireless Power Transmission and the five big breakthroughs that are enabling this emerging technology to transform the way consumers and industries wirelessly charge and power electronic devices at home, in the office, in the car and beyond.

High Power Dynamic Wireless Charging for Trucks

Mr. Andy Daga

CEO and Co-founder, Momentum Dynamics

Abstract: As the world moves forward toward electrified transportation and logistics, it has become increasingly clear that charging infrastructure is critical to the rate of adoption, and even the rate of production of electric vehicles. We recognize that not all-electric vehicles are passenger cars – in fact, they necessarily include every type of vehicle – including all classes of trucks, buses, industrial equipment, logistics handling, and even rail and marine vehicles. Each of these use cases has a set of technical, operational, and economic requirements. The common challenges in the deployment and operation of EV charging infrastructure that can meet the needs of all of these types of vehicles are: maximizing utilization of the vehicles and charging equipment; minimizing the capital expense of the infrastructure and determining who will bear it; minimizing overall operating expense (including charging costs) and simplifying operations; operating within spatially constrained areas; minimizing changes to efficient operations; and determining how operators of charging equipment can build sustainable, profitable economic models. To date, these challenges have not been adequately addressed by manually operated conductive (or plug-in) charging. The presentation will provide a status update on the commercialization of automatically operated inductive charging, and how inductive charging has proven its capacity to solve each of these problems. The case for a common automatic charging system composed of inductive charging modules that can be scaled to any type of vehicle and any power level will be made.

Speaker's Bio: Andy’s fascinating story takes him from his birthplace of Brooklyn, NY, through Ithaca NY where his family developed the best Italian Restaurant in town through Hawaii, degrees in structural and civil engineering, architecture and space science and technology, ground-breaking work at NASA and his current role at Momentum Dynamics. Prior to founding Momentum Dynamics, Andy was a leading consultant to the aerospace industry and contributed to the design of the International Space Station solar power array system, the Mars Pathfinder program, and future mission planning studies with NASA and the US Department of Defense. Andy will admit that this layered journey wasn’t fully planned, but nor did it happen by accident: as a child, Andy would travel with his family from his home in Brooklyn to visit their extended family in Philadelphia, PA (hence our home today in Malvern PA). This route took him through New Jersey and past the bleak refineries of Route 95. As a lover of architectural beauty, the outdoors and being obsessive about ‘all things efficiency’, the New Jersey oil refineries were the antithesis of everything Andy wanted the world to be. Fast forward to Andy’s time at NASA. He came upon the idea of inductive charging while mulling on ways to save cable weight on the International Space Station and future Mars missions. Why employ heavy cabling to carry electrons when it could be done efficiently through a vacuum or even the air itself? Out of this thought was born Momentum Dynamics. Through his varied experiences Andy has developed a strong capacity to identify engineering talent and manage multidisciplinary engineering and business teams. Andy is a member of the Institute of Electrical and Electronics Engineers (IEEE), and the Society of Automotive Engineers (SAE) where he serves on a number of standards committees. He believes that every precious piece of our finite resources should be fully valued and carefully spent. He envisions a world of zero emissions, zero cables and zero wasted miles doing anything but making our lives better. He is a devoted husband, family man, polymath and entrepreneur. He is passionate about his dogs and his team at MD – perhaps in that order. He is still working to make the world a better place, one electron at a time.

Wireless Charging for Electric Vehicles: Moving to Mainstream

Dr. Morris Kesler

Chief Technical Officer, Witricity

Abstract: The desire for wireless charging of electric vehicles has been around for at least a decade and is now poised to move onto mainstream electric vehicles (EVs). Interest in EVs and in electric mobility, in general, has never been greater, and automakers and other E-mobility companies are investing heavily in new platform development. Wireless charging technology is ready to make charging these platforms a simple, hassle-free experience and even enable new opportunities for mobility and autonomy. The first standard development activity for EV wireless charging recently (October 2020) culminated with the publication of the SAE J2954 standard for wireless charging of light-duty vehicles. This opens the door for broad deployment, providing a means for creating systems that are interoperable across different manufacturers and vehicle types and makes public wireless charging infrastructure possible. However, a wireless power product involves much more than just power transfer. In this presentation, we will review requirements for a practical EV wireless charging system, explore key system considerations and solutions, and look at where the technology is headed as we move into the age of E-mobility.

Wireless Charging for Electrified Roadways

Dr. Burak Ozpineci

Distinguished R&D Staff Head | Vehicle and Mobility Systems Research Section, Oakridge National Laboratory (ORNL), USA

Abstract: With the demonstrations of high power static wireless charging systems, high power dynamic wireless charging is a possibility for future electrified roadways. Dynamic wireless charging feasibility has been studied at Oak Ridge National Laboratory (ORNL) where it was shown that with higher than 200kW wireless power transfer, less than 10% of each mile could be electrified for charge sustaining operation. The idea is not necessarily charging the electric vehicle batteries to full state of charge but to provide enough energy to the vehicles so that the charge they use during a mile of roadway can be recovered. This potentially opens up opportunities for unlimited range for electric vehicles. A recent update on ORNL’s work in this area will be covered in this presentation as well as challenges observed. Possible comparisons to extreme fast charging systems will also be discussed.

Speaker's Bio: Burak Ozpineci received the B.S. degree in electrical engineering from Orta Dogu Technical University, Ankara, Turkey, in 1994, and the M.S. and Ph.D. degrees in electrical engineering from The University of Tennessee, Knoxville, TN, USA, in 1998 and 2002, respectively. In 2001, he joined the Post-Master’s Program with Power Electronics and Electric Machinery Group, Oak Ridge National Laboratory (ORNL), Knoxville, TN, USA. He became a Full Time Research and Development Staff Member in 2002, the Group Leader of the Power and Energy Systems Group in 2008, and the Group Leader of the Power Electronics and Electric Machinery Group in 2011. Presently, he is serving as the Section Head for the Vehicle and Mobility System Research Section and managing the Electric Drive Technologies Program at ORNL. He also serves as a Joint Faculty with the Bredesen Center, The University of Tennessee. Dr. Ozpineci is a Fellow of IEEE.

Jesse Schneider

Chair, SAE Wireless Power Transfer Taskforce, J2954; CEO/ CTO at ZEV Station

Abstract: Electric and Plug-in Electric vehicles are just beginning to be commercialized in large scale production which are charged through conductive charging with multiple plug types. There are numerous advantages which wireless power transfer (WPT) offers, effectively charging without cables, related to improved customer acceptance of the charging and automatic charging of autonomous electric vehicles. In order to establish a worldwide standard, to ensure a smooth implementation of the WPT to 11kW related to safety, performance, interoperability vehicle alignment SAE published the J2954 standard. The standard establishes a specification for the vehicle & infrastructure EVSE coils, EMC/EMF limits and a common methodology for validation and testing WPT. An overview of the newly published Standard, SAE J2954 will be given including some background for the testing with automaker and supplier systems to validate. In addition, plans for the next phase of standardization for both light and heavy-duty electric vehicles will be given.
