Volvo is testing and integrating new wireless charging technology for electric vehicles. The testing will occur over a 3-year period and will involve a fleet of fully electric Volvo XC40 Recharge cars that will be used as taxis and charged wirelessly at stations in Gothenburg, Sweden.
“Gothenburg Green City Zone lets us try exciting new technologies in a real environment and evaluate them over time for a potential future broader introduction,” said Mats Moberg, head of Research and Development at Volvo Cars. “Testing new charging technologies together with selected partners is a good way to evaluate alternative charging options for our future cars.”
The charging starts automatically when a compatible vehicle parks over the charging pad that’s embedded in the street. Energy is sent through the charging pad that’s picked up by the receiving unit in the vehicle. To make lining up the vehicle on the pad easier for the driver, Volvo will use its 360-degree camera system.
For the Volvo XC40 Recharge cars the wireless charging power is more than 40 kW, making it approximately four time faster than a wired 11 kW AC charger, and almost as quick as a wired 50kW DC fast charger.
The Volvo XC40 Recharge cars will be used more than 12 hours a day and driven 100,000 km (62,137 miles) annually. Volvo Cars will use it as the first durability test of fully electric vehicles in a commercial usage scenario.
i have a great idea for charging cars while in motion g-mail me at maynard2372@gmail,com till later go green super idea should be heard billion dollar idea, thomas jandre
It’s not rocket science… you simply have a secondary winding on the bottom of the vehicle (half of a transformer) with the primary winding in the street/pad. AC voltage in inductively coupled into the secodary… rectified… and current-regulated to the battery, with provision for prevention of back feeding (the rectifying diode bridge takes care of that). …but HEY… why not put a secondary winding into the fiberglas BODYWORK, so when you drive down those endless miles of interstate, with those 39KV powerlines up above, the car “scavanges” power from THEM as well?
