ElectReon has successfully wirelessly charged a fully electric 40-ton truck and trailer at a test facility in Sweden. The next step will be to charge the truck through dynamic wireless power transfer on a public road in Gotland, Sweden. The Smartroad Gotland project is the first wireless electric road system (ERS) for trucks and buses on public roads. ERS supports electric power transfer to vehicles while in motion and has the potential to increase energy efficiency with a reduced need of batteries. The dynamic wireless power transfer (DWPT) system consists of three key elements; the coil transferring energy to a receiver on the vehicle and a management unit controlling the process. The management unit is connected to the electric grid and transfers energy to copper coils buried 8 cm below the roadway, when a valid vehicle is exactly above. The energy is wirelessly transferred from the coil to a […]
