Qualcomm Shows How To Wirelessly Charge Electric Vehicles While Driving


While there are technologies being introduced to make batteries better, Qualcomm is pushing itself ahead by working on a technology that doesn't need you to stop your vehicle to charge it.

Not only would this technology be useful for current EV enthusiasts, but it would be huge for the widespread adoption of electric cars. Qualcomm on Thursday demonstrated the ability to recharge two Renault Kangoo EVs for up to 20 killowatts while they traveled at highway speeds, using the San Diego company's dynamic electric vehicle charging (DEVC) system. He calls DEVC "a solid, robust, and fit for objective dynamic charging system for electric vehicles". Unlike a tram (or even a slot car) that must remain connected to a power source at all times, away from dynamic charging roads the specially equipped Kangoo Z.E. functions like a normal electric vehicle. The technology was able to charge the vehicles' batteries at speeds of over 100 km/h (62 mph), with them travelling in either direction.

"The tests will evaluate the operation 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 said. "Our engineers have worked very closely with Qualcomm Technologies".

The dynamic charging project began in 2017, with evaluation of the system set to take place until the end of 2017 with 25 partners and nine European countries involved in the program. The main aim of FABRIC is to conduct feasibility analysis of wireless DEVC as a means of EV range extension.

Qualcomm is the latest company to unveil a DEVC system this week. "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". The DEVC system has been created to support real-world implementation of dynamic charging.

"We are inventors. We are WEVC. This dynamic charging demonstration is the embodiment of this", said Steve Pazol, vice president and general manager, Wireless Charging, Qualcomm Incorporated.

The technology, which is being trialled at the Fabric technology test track south of Paris, is based around United States tech company Qualcomm's Halo wireless charging system, which is used to charge Formula E's BMW i8 safety vehicle.

Qualcomm made it clear it will not manufacture the equipment and prefers a licensing business model.
