Sophisticated wireless charging offers EV advance

Sophisticated wireless charging technology could offer major benefits to users of electric vehicles. A number of firms have been working together on developing new wireless charging systems that could reduce delays and extend range for drivers. Inductive-charging systems are being tested at present, with Renault carrying out research in Europe on its electric vehicles. The inductive-charging technology relies on the use of electrically-wired pads that generate electro-magnetic fields. When a car is positioned over one of these pads, even for a short period, its batteries will receive a short charging burst that will top up batteries and extend range before a full recharge is required. Positioning the pads at traffic lights, in parking areas for convenience stores or in the garages of vehicle owners would allow recharging. And this would mean there would be no need to plug the vehicle in for recharging to be carried out. The technology could also help address the issue of range anxiety, the concerns over how much charge remains in a battery, which has so far hindered sales of electric vehicles.
