Using inductive transfer of energy, Qualcomm has developed a technology capable of wirelessly charging Electric Vehicles (EVs) – even when driving.
Qualcomm’s Halo EV charging technology uses inductive wireless energy transfer to eliminate the plug-in cord used for most EVs today. The technology works by fitting cars with a receiver pad that enables automatic charging when the car is parked via a transmitter pad embedded in the road.
Qualcomm claims that its technology transfers power with the same efficiency as a cable. The company aims to embed wireless charging in continuous strings along the roadway, with EVs constantly being powered as they drive over them.
A two-year feasibility study has been carried out in London, to learn more about the feasibility and issues around charging EVs wirelessly in an urban centre. Additionally, Mercedes-Benz have announced that one of their 2018 models will include wireless charging technology, indicating that one of the leading manufacturers is backing the technology.
Why you should care
Wireless EV charging addresses key challenges to electric car uptake: charging convenience and battery size and cost. The technology could be rolled out in public parking facilities and strategically across the road network before expanding further. The more charging spots, the greater the potential reductions in battery size for EVs.
