Keynote Session 1

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. Cesar Johnston is Chief Operating Officer and Executive Vice President of Engineering for Energous. He’s responsible for accelerating open innovation in new and emerging wireless power technologies, systems, and markets. Cesar is a seasoned technologist, entrepreneur, and investor. Prior to Energous, Cesar has had a broad experience in large enterprises and startups. He has previously served as Vice President of Engineering for Wireless Connectivity at Marvell Semiconductor. During his time with Marvell, Cesar led Marvell’s worldwide R&D and development of all Wi-Fi, Bluetooth, FM, and NFC products. Prior to Marvell, Cesar drove technology innovation at Broadcom responsible for 802.11g and 802.11n products.

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.

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.

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.

Morris Kesler is the Chief Technology Officer at WiTricity Corporation where he leads research and development activities in wireless power technology. He joined WiTricity in 2007 and has served as Chief Engineer and vice president of research and development.

Wireless Power 2.0: What Will It Take to Get There and When Will It Happen?

Dr. Alex Lidow, CEO and Co-founder, Efficient Power Conversion, USA

Abstract: There are hundreds of millions of people who have experienced the first generation of wireless power transfer technology based on inductive coupling and the Qi format. The promise of convenience has only partially been realized as the limitations of precise positioning and slow charging speeds have become more acute as fast charging of cell phones has become more important to the consumer. Magnetic resonance has long promised to overcome the limitations of Qi with its ability to (a) safely transfer much higher power, (b) enable spatial freedom stemming from large surfaces that can produce uniform magnetic fields, and (c) the ability to have one transmitter couple to a multitude of receivers. In this talk we will discuss the technological, financial, and emotional barriers that need to be broached before widespread consumer adoption of this next generation wireless power technology will gain traction.

Alex Lidow is CEO and co-founder of Efficient Power Conversion Corporation (EPC). Since 1977 Dr. Lidow has been dedicated to making power conversion more efficient upon the belief that this will reduce the harm to our environment and increase the global standard of living.

Addressing the Charging Problem for Every Vehicle Type: Universal Wireless Power

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.

Andy Daga’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

29 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.

Worldwide Standardization of Wireless Power Transfer for EVs, SAE J2954

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.

Shaping the Future of RF Wireless Power Transmission Cesar Johnston, Chief Operating Officer and Executive Vice President of Engineering, Energous

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.

To Get A Grip on The Earth and Shake It: Nikola Tesla’s Scheme for Wireless Power Transmission W. Bernard Carlson, Vaughan Professor of Humanities, University of Virginia

Along with developing a practical AC motor, Nikola Tesla [1856-1943] contributed to electrical engineering by working for fifteen years on a scheme to transmit power wirelessly around the world. Inspired by the experiments of Heinrich Hertz and spurred on by a rivalry with Guglielmo Marconi, Tesla built two broadcasting stations, first in Colorado Springs [1899-1900] and then at Wardenclyffe on Long Island [1901-1905]. At these locations, Tesla pumped energy into the earth’s crust in order to set up a stationary electromagnetic wave at the earth’s resonant frequency. Tesla believed that people would tap into this wave for power and messages by simply grounding a receiver that “would be no bigger than a pocket watch.” In this talk, I will outline the evolution of Tesla’s thinking about wireless power in the 1890s and 1900s as well as his unsuccessful efforts to launch a business around this technology with funding from J.P. Morgan and others. Overall, I will suggest that Tesla was motivated to provide messages and power to millions of people and hence was among the first to recognize that the Information Revolution of the twentieth century would be about empowering individual users.

Wireless Power and Power Beaming Paul Jaffe, U.S. Naval Research Laboratory (NRL)

Language and nomenclature affect the way we think. In recent years, the taxonomy of wireless power has grown to include technologies and modalities across a wide range. Whether it refers to short- range energy

transmission between systems without connectors or long-range delivery of energy over distances far exceeding a meter, there is value in defining the different classifications of wireless power transmission. In this keynote, Dr. Jaffe will give a summary overview of different approaches to one such classification scheme, in which power beaming will be distinguished as a clear subset of wireless power transmission. He will review recent progress for microwave, millimeter-wave, and optical power beaming, and discuss near-term plans and next steps. The discussion will be framed by the contexts of emerging applications and of longer-term visions of future possibilities.

Addressing the Charging Problem for Every Vehicle Type: Universal Wireless Power Andrew Daga, CEO and Co-founder, Momentum Dynamics

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.

Safety of RF Wireless Power Transfer Technology James Lin, Professor Emeritus, University of Illinois at Chicago

Wireless power transfer (WPT) systems are being deployed to provide needed electric power either directly or via battery-charging services using a very wide spectrum. The optimism on WPT technology is clearly driven by the ubiquity of cell phones, laptops, and other mobile communication devices. Aside from not having to plug in the mobile phone or laptop, an fascinating cause for the interest in battery charging through WPT comes from the potential for mobile communication devices to get their electrical power the same way they get their data through harvesting ambient electromagnetic radiation. The dream is a truly wireless mobility scenario with completely tether-free electric power supply for mobile phones, laptops, electric appliances, and various transportation systems. Beyond wireless communication uses, the level of transmitted electromagnetic power required for large-scale or commercial implementation of WPT would be substantial. A key facet of the system design and research effort should include consideration of biological effects and human safety, especially in the RF region of the electromagnetic spectrum. This talk will feature my perspectives

on RF safety of WPT technologies.

Abstract: Currently, there is a strong drive to electrify the transportation sector as a solution to the environmental and economic impacts of vehicles using internal combustion engines. However, to-date, limitations of battery technologies have hindered the uptake of electric vehicles (EVs). For example, the main drawbacks commonly associated with EVs are the limited range and long charging times, both of which are a direct result of the low energy and power densities of current battery technologies. These issues are further aggravated due to the fact that the EVs need to be plugged-in to refuel, as it can take many hours to fully-charge a depleted EV battery. Although, fast and extreme fast charging systems have been developed and deployed to help EV users refuel in a fraction of an hour, this is achieved at the expense of battery life and user safety. In contrast, wireless charging of stationary and in- motion electric vehicles promises a future where EVs are replenished organically, thus avoiding long charging times, range anxiety and battery degradation. An ubiquitous wireless charging infrastructure, especially one that is bi-directional, can be used to provide grid services, thus not only drastically improving the uptake of EVs, but also supporting grids with high penetration of renewable electricity. This workshop will start with a brief discussion on the history of wireless power transfer (WPT) technology. Subsequently, the fundamental operating principles of a wireless EV charger will be presented, and commonly used wireless charging and magnetic solutions will be reviewed. This will be followed by a discussion on some of the unique magnetic topologies developed by the WPT research group at the University of Auckland, highlighting their key features and benefits. To conclude the presentation, our vision for a ubiquitous wireless charging infrastructure will presented along with key research questions that needs to be addressed to make this vision a reality.

• EMC and EMF Safety Issues in Near Field Wireless Power Transfer Systems

• Mauro Feliziani, University of L’Aquila, Italy Abstract: The objective of this presentation is to analyze aspects of electromagnetic compatibility (EMC) and electromagnetic field (EMF) safety of near-field wireless power transfer systems. In particular, the next generation of electric vehicles (EVs) equipped with WPT systems is being studied. WPT systems used to wirelessly recharge electric vehicle internal batteries are intentional sources of time-varying magnetic fields in and around electric vehicles. A major concern is therefore the compliance of emitted magnetic fields with EMC and EMF safety standards and regulations, also because the use of traditional magnetic field mitigation technique is not efficient, or can reduce the performance of the WPT systems. Additionally, the use of carbon fiber reinforced polymer (CFRP) for EV bodyshells increases public health concerns as CFRP is quite transparent to the magnetic field. The talk is primarily aimed at advanced models and methods for shielding, field mitigation, coil design, and human exposure. The evaluation of electromagnetic interference (EMI) of active implantable medical devices (AIMDs) in patients inside and outside electric vehicles is also presented. Finally some information is provided on dynamic WPT systems in urban and suburban areas.

• WPT Patent Landscape

• Fritz M. Fleming Abstract: On January 1, 2013, the United States Patent and Trademark Office (USPTO) moved from using the United States Patent Classification (USPC) system to the Cooperative Patent Classification (CPC) system, a jointly developed system with the European Patent Office (EPO). CPC has now been adopted by many countries throughout the world. This short course will provide an introduction to the Cooperative Patent Classification (CPC) system and where various WPT technologies are classified. The evolution of WPT patent classification will be discussed with an emphasis on the advantages of using CPC, as well as differences between CPC and IPC (International Patent Classification) used by WIPO (World Intellectual Property Organization). In CPC, WPT is primarily classified in H02J50, and each of the subgroups will be introduced, as well as a few areas outside of H02J50. Finally, to round out the WPT patent landscape, a graphical representation of patent publication trends will be considered. The end goal is not to make the audience an expert in patent classification, but to make the audience aware of the relevant areas of CPC for WPT. Bio: Fritz M. Fleming is a registered patent agent working as a patent consultant with Henry Feiereisen LLC based in New York City, a well-established intellectual property services firm founded in 1983, specializing in the representation of German speaking clients in all phases of the patent prosecution process. Before becoming a registered patent agent, Fritz was on active duty with the United States Air Force at Hill AFB, Utah as an F-16A Instrumentation Engineer from 1985-1990. Fritz then joined the United States Patent and Trademark Office (USPTO) as a patent examiner in 1991, where he worked until he retired in 2019. While at the USPTO, Fritz primarily examined power distribution technologies (USPC 307, now CPC H02J), seeing his first WPT application in 1992. Over the decades to follow, the number of WPT filings steadily increased and he became very interested in WPT and saw the various WPT technologies and applications evolve during his tenure at the USPTO. In 2014, he went to the EPO in Munich as part of a USPTO delegation to discuss the switch from USPC to CPC and the need for a more detailed classification of WPT given the rapidly increasing filings in WPT. Fritz also served as a Quality Nominee (QN) and worked with EPO

70 counterparts to make major revisions to the H02J schedule in CPC, including the addition of new subgroups for WPT in H02J50. During his time at the USPTO, he examined over 1600 patent applications, with over 160 of those being WPT related. He also taught WPT technology and classification to fellow examiners and the contractor responsible for re-classifying a large portion of WPT patent documents in H02J. He reviewed the work of many junior patent examiners and performed quality control over random samples of the contractor’s reclassification work. While at the USPTO, Fritz also served as an advanced technology analyst in the United States Air Force Reserves at the Defense Intelligence Agency. Fritz graduated from Southern Methodist University, Dallas, Texas, in 1985 with a BSEE (Summa Cum Laude, Tau Beta Pi, and Eta Kappa Nu) and minors in German and Applied Mathematics. He has a Master of Science Degree in Physics from the University of Utah, Salt Lake City, Utah (1990). Fritz also graduated from Squadron Officer School, Maxwell AFB, Montgomery, Alabama (1989). He currently lives in rural Virginia on a small farm with his wife and daughters.

• Analysis and Benefits of GaN in High Frequency Applications

• Paul Wiener, GaN Systems Abstract: The last cord to cut is power. We did it with our phones moving from landline to IP or mobile phones and with Internet connectivity from dial-up to Wi-Fi. There is a lot of excitement and commitment to bring wireless power mainstream. But one thing remains clear the current low frequency wireless power transfer (WPT) technology is low power, slow charging and low efficiency – this will not advance the market. What is needed is high power, fast charging, high efficiency, drop-and-charge placement, multi-device charging flexibility with power levels suitable for all markets and gallium nitride (GaN) power transistors can deliver this. Applications getting attention and penetrating the market include robots, drones, ebikes, power tools and medical devices. In this workshop, Paul Wiener of GaN Systems will give an overview of wireless power today and will go into detail on the limitations of WPT1.0, the wireless power user requirements, and the need to move to WPT2.0, and how GaN transistors are enabling these higher power level applications. Paul will lead an interactive workshop where attendees will come away with a better understanding of gallium nitride, its importance in wireless power and the reliability of the technology, the GaN market and where the primary growth will occur in the next several years. Bio: Paul Wiener is GaN Systems’ Vice President of Strategic Marketing. Prior to joining GaN Systems, Paul led the power magnetics business unit at Eaton. Paul brings more than 25 years’ experience in operations, sales and marketing, and business development. His experience includes vice president of sales at Fultec Semiconductor Inc. and several management roles at Genoa, BroadLogic, and Raychem. Paul earned his MBA from Golden Gate University and his bachelor’s degree in business from the University of California at Berkeley.

Workshop for Novel Compact Size Single and Multi-bands DGS Resonators for Wireless Power Transfer, and Energy Harvesting

• Coupled Defected Ground Structures Resonators Principles and Applications • Adel Bedair, Egypt-Japan University of Science and Technology, Alexandria, Egypt.

Abstract: This presentation introduces a novel technique for high efficiency and compact size wireless power transfer (WPT) systems. These systems are based on coupled defected ground structure (DGS) resonators with high quality factor, the DGS resonator is loaded by chip capacitors for miniaturization. Simulated electric field and magnetic field intensity within a DGS structures will be presented. Procedures for DGS equivalent circuit extraction using approximate quasi-static modelling will be developed. The theory for realizing the coupling matrix using coupled DGS resonators will be detailed. An analytical design procedure is then developed to calculate the optimum design parameters for a proposed WPT system. Performance improvement of different types of filters using DGS Structures, including 3D DGS coupled resonator filter will be reviewed. Different shapes of DGSs (H- shape and semi-H-shape) are proposed. The semi-H-shaped DGS realizes larger inductance value, and this results in higher WPT efficiency. Instead of using an inductive-fed resonant coupling, we propose capacitive-fed resonant coupling, which reduces the design complexity and enhances the efficiency further. The optimized structures are fabricated and measured. The simulation and measurement results are in good agreement. The proposed semi-H-shaped DGS WPT system has a peak efficiency of 73% at a transmission distance of 25 mm. Bio: Adel B.

• Dual-band Rectenna Using Voltage Doubler Rectifier and Four-Section Matching Network • Ahmed Allam, Mohamed Ali, Egypt–Japan University of Science and Technology, Alexandria, Egypt.

Abstract: This presentation introduces the design, fabrication and measurement results of a dual-band rectenna with maximum measured conversion efficiency of 63% and 69% at f1 = 1.95 GHz and f2 = 2.5 GHz, respectively over wide band of the input power, 14 and 15.5 dBm for conversion efficiency above 50% at f1 and f2, respectively with RL = 1KΩ. In addition, a dual-frequency band low input power rectenna will be presented. The rectenna comprises a cpw rectifier integrated with rectangular split ring antenna loaded by spiral strip line. Single diode series connection topology is used to miniaturize the losses at low input power. Spiral coil in addition to two short circuit stubs are used as a matching network for maximum power transfer between the antenna and the rectifying circuit. The rectifier is optimized and fabricated, then integrated with the antenna to introduce the proposed rectenna. The proposed rectenna operated at low input power with relatively high measured RF-DC conversion efficiency up to 74% at −6.5 dBm at the first resonant frequency f1 = 700MHz and 70% at −4.5dBm at the second band f2 = 1.4GHz at resistive load of 1.9KΩ. The measured rectenna sensitivity (the rectenna ability to receive low power with acceptable conversion efficiency) reaches up to −20dBm with conversion efficiency of 47% and 36% at f1 and f2, respectively and dc output voltage of 0.18V. The measured efficiency is over 50% from −18 to −3.5dBm and from −15 to −1.5dBm at f1 and f2, respectively. The antenna, as well as the rectifier circuit, are designed and tested separately. Finally, the matching circuit is designed, and the integration is done on the same PCB substrate.
