ITIC Automotive Test Bed Offers Wireless Charging as a Service
GREENVILLE, S.C., October 27, 2015 /3BL Media/ — The International Transportation Innovation Center (ITIC) is the host site for a new wireless charging R&D test bed for electrified automotive vehicles. The wireless power transfer test bed was developed by Clemson University’s International Center for Automotive Research (CU-ICAR) in collaboration with Oak Ridge National Laboratory, ITIC, Toyota, Cisco, Duke Energy and Evatran.
The test bed has been part of a major collaborative R&D initiative that recently passed a formal project review by the U.S. Department of Energy (DOE).
The ITIC facility becomes one of the first operating wireless charging test beds in the U.S., where entities may use its capabilities as an R&D service. Entities can do this without a business partner that has previously researched new wireless charging technology and services.
This achievement opens the door for ITIC to begin marketing wireless charging test and development services to automotive manufacturers, suppliers and related technology companies. It also allows program collaborators to move forward with the next project phase: the testing of wireless charging of moving electric vehicles (dynamic or in-motion wireless charging). Those tests will begin later this fall in a program directed by CU-ICAR at ITIC.
The first test demonstrated wireless power transfer systems integrated into two different Toyota vehicle models. One of the vehicles was tested at a power transfer rate of 6.9 kilowatts and achieved an overall efficiency of greater than 85 percent. The systems tested used wireless power transfer technology developed by Oak Ridge National Laboratory and communication tools developed in collaboration with Cisco.
The wireless power transfer project development started in 2013 after Oak Ridge National Laboratory (ORNL) received an $8.1 million grant from the Department of Energy. ORNL subcontracted CU-ICAR to develop the grid-side and vehicle-side communication system for wireless charging, and researched the potential impact of electromagnetic fields.
CU-ICAR partnered with ITIC to develop a physical test bed to support the testing of the vehicle and infrastructure interaction during the wireless charging process.
The Virginia-based company Evatran integrated the coil systems and power electronics components developed by ORNL into the test vehicles provided by Toyota. CU-ICAR and Cisco collaborated on the development of the communication radios, both in the vehicles and on the roadside. Duke Energy provided the grid connectivity and the power supply infrastructure. CU-ICAR guided ITIC in the layout and design of the physical test bed, and in the development and monitoring of the test procedures.
Researchers now are preparing for the next project phase of wireless charging of vehicles moving over a sequence of coils commonly referred to as Dynamic Wireless Charging (DWC).
The ITIC wireless charging test bed can support both stationary as well as in-motion wireless charging. Although the first development stage of in-motion wireless charging will be performed at lower speeds (under 35 mph), a built-out option already has been identified on a mile-long straightaway road segment to test dynamic wireless charging at higher speeds. The ITIC test bed has been prepared to also support higher power levels of up to 250 kilowatts.
“We are excited to see how the many pieces of system design, vehicle integration and test bed implementation are finally coming together,” said P.T. Jones, the ORNL program manager of the overall project effort. “This has been a great collaborative effort between multiple partners to show the benefit of wireless charging for the world of transportation and support the future of the technology.”
CU-ICAR Principal Investigator and ITIC Chief Technology Officer Dr. Joachim Taiber explains “The integration of stationary and in-motion wireless charging of electrified vehicles into one scalable test bed and the development of a suitable communication and grid infrastructure that can support different speed and power levels makes this test site layout and location unique.”
Jae Lee, Toyota research and development manager, said “We see great potential in understanding the technology of wireless charging to deliver value to our customers. In particular, we see the need to work more on dynamic wireless charging and to automate the charging process.”
Ashok Moghe, Principal Engineer, Chief Technology and Architecture Office, Cisco, said “This has been a great team effort across the connected vehicle ecosystem. The communication solution developed in collaboration with Cisco and CU-ICAR and validated at ITIC is a critical piece in a multi-mode wireless power transfer platform.”
Mike Rowand, Director Technology Development at Duke Energy, said “Preparing for the future infrastructure requirements for electric vehicles is important to Duke Energy, therefore we are pleased to collaborate with Clemson University ICAR and their partners in the establishment of a wireless charging test site at the ITIC.”
