Renault has partnered with Qualcomm Technologies and Vedecom around a project aimed at dynamic recharging, in other words charging the batteries of an electric vehicle while it is on the move. In the trial carried-out on the test track, two Renault Kangoo Z.E. have been able to recharge their batteries simultaneously travelling in both directions, specifically delivering a charge of 20 kW at a speed of up to100 km/h.
The dynamic charging demonstration was carried-out in the 100 meters long test track built by Vedecom in Satory, Versailles, near Paris, under the project FABRIC. Qualcomm Technologies and Vedecom have installed the primary part of the dynamic electric vehicle charging system on the test track while Vedecom and Renault have integrated the ancillary parts into two Renault Kangoo Z.E.
Vedecom will soon launch a new testing phase. These tests will evaluate the operation, safety and efficiency of energy transfer to the vehicles for a wide range of practical scenarios including vehicle identification and authorization on entering track, power level agreement between track and vehicle, speed and alignment of vehicle along track, Renault reports in a statement released by NewsPress.
The tests are part of the EUR 9 million FABRIC project, partly funded by the European Union. It addresses the technological feasibility, economic viability and socio-environmental sustainability of the wireless dynamic electric vehicles charging. It began in January 2014 and will continue through December 2017.
FABRIC is comprised of a consortium of 25 partners from nine European countries, including automotive manufacturers, equipment manufacturers, service providers and research organizations on automotive, road and energy infrastructure. FABRIC´s main objective is to carry out a feasibility analysis of the wireless dynamic charging of electric vehicles as a means of extending electric vehicles ranges, Renault notes.
“Contributing to this exciting project has allowed us to test and continue to seek the dynamic recharging on our Kangoo Z.E.,” says Eric Feunteun, director of Renault Group’s Electric Vehicles Program. “Our research engineers have worked closely with the Qualcomm Technologies and Vedecom teams to achieve a successful demonstration of the integration of dynamic electric vehicle charging system under FABRIC. We regard dynamic recharging as a way to further improve utilization of electric vehicles and their accessibility ” he adds.
“We are inventors, we recharge electric vehicles with no need of a cable. This dynamic recharging demonstration embodies this idea” said Steve Pazol, vice president and general manager, Wireless Charging, Qualcomm Incorporated. “I am very proud of what we have done. The combination of a team of expert engineers from around the world and Qualcomm Halo technology, which covers all aspects of WEVC, regardless of the magnetism used, has allowed us to go further on and describe our vision of the future of urban mobility, “he said.
