Based on the Qualcomm Halo™ wireless electric vehicle charging technology (WEVC), Qualcomm designed and built a wireless electric vehicle charging system capable of charging an EV dynamically at up to 20 kilowatts at highway speeds.
A charging strip is laid on the road and can charge an EV as it rolls over the strip. To show how it works, Qualcomm equipped two Renault Kangoo vehicles with Qualcomm's Halo DEVC receivers.
Qualcomm also demonstrated simultaneous charging, in which two vehicles on the same track can charge dynamically at the same time.
The vehicles can pick up charge in both directions along the track, and in reverse, showing how the Qualcomm Halo DEVC system supports real-world implementation of dynamic charging.
The dynamic charging demonstrations took place at Satory Versailles, an sparsely populated area of Versailles, capital of the Yvelines department, in north-central France.
FABRIC is a €9 million project, mostly funded by the European Commission, addressing the technological feasibility, economic viability, and socio-environmental sustainability of wireless dynamic electric vehicle charging.
The project began in January 2014 and will continue through December 2017.
It is being conducted by a consortium of 25 organizations from nine European countries, including automotive manufacturers, suppliers, service providers and research organizations from automotive, road and energy infrastructure domains.
The test track was built by VEDECOM, the Institute for Energy Transition, set up within the framework of the French government's Future Investment Program, which is dedicated to individual, low-carbon and sustainable mobility.
VEDECOM is one of the FABRIC collaborators. It is responsible for providing the demonstration of dynamic charging at Satory using the Qualcomm Halo DEVC system.
"Our engineers and management have fully supported this project since the very beginning as it aligns perfectly with our focus on EVs, charging systems and mobility services," said Luc Marbach, chief executive officer, VEDECOM.
"We are a public-private partnership focused on pre-competitive research," Marbach said. "The installation of one of the world’s first DEVC test platforms has provided us with a unique test facility and we look forward to expanding our expertise with the future testing."
Many partners are involved in this research. At Satory Versailles, there is a laboratory on vehicle-infrastructure-driver interactions, a research unit focusing on the automated road, the so-called "intelligent road" of tomorrow.
Research conducted there is dependent on the French institute of science and technology for transport, spatial planning, development and networks, a public research institution created in 2011.
Qualcomm Technologies and VEDECOM integrated the source part of the Qualcomm Halo DEVC system in the test track, while VEDECOM and Renault integrated the receiving part onto two Renault Kangoo vehicles.
"Being part of this exciting project has enabled us to test and further research dynamic charging on our Kangoo Z.E. vehicles," said Eric Feunteun, electric vehicle program director, Groupe Renault.
"Our engineers have worked very closely with the Qualcomm Technologies and VEDECOM teams to complete the DEVC system integration demonstration as part of FABRIC," said Feunteun. "We see dynamic charging as a great vision to further enhance the ease of use of EVs, thus the accessibility of EVs for all."
Now that the demonstration is completed, the Qualcomm has handed over the Halo DEVC system to VEDECOM to perform tests for FABRIC.
The tests will evaluate the operation, safety and efficiency of energy transfer to the vehicles for practical scenarios, such as vehicle identification and authorization on entering track, power level agreement between track and vehicle, speed and alignment of vehicle along track.
Steve Pazol, vice president and general manager, wireless charging, Qualcomm Incorporated, said, "We are inventors. We are wireless electric vehicle charging technology. This dynamic charging demonstration is the embodiment of this."
"I am immensely proud of what we have achieved," said Pazol. "The combination of a global team of expert engineers and Qualcomm Halo technology, which covers all aspects of WEVC systems, irrespective of the magnetics used, has enabled us to really push the boundaries of the possible and outline our vision for future urban mobility."
Qualcomm's technologies powered the smartphone revolution and connected billions of people, Pazol explained. "We pioneered 3G and 4G, and now we are leading the way to 5G and a new era of intelligent, connected devices."
"Our products are revolutionizing industries," he said, "including automotive, computing, IoT, healthcare and data center, and are allowing millions of devices to connect with each other in ways never before imagined."
