The ability to charge electric vehicles using inductive and cable-free technology would make it possible to ’fill-up’ with electric charge more often and for shorter periods of time. In turn, this would enable such vehicles to be fitted with smaller batteries, which would reduce lithium use and save time. The Institute of Electrical Energy Conversion (iew) at the University of Stuttgart has applied for multiple patents for this technology. [Picture: University of Stuttgart / Max Kovalenko]

Picture: University of Stuttgart / Max Kovalenko] - The researchers working with Nejila Parspour at the iew develop wireless electrical road networks, where electric cars and commercial vehicles can be automatically charged, either when moving or stationary, for example when parked on a parking lot or waiting at traffic lights. To enable this, inductors are embedded into the road surface. As soon as the vehicle drives over these it activates the charge coils in the road and electrical energy is transmitted to the vehicle via a magnetic field. This technology can significantly increase the range of electric vehicles.
