E-vehicle Can be Charged Automatically

Electric Vehicle’s charging is the biggest issue, nowadays. Many charging stations have to be installed in the country and numbers of startups are working on the same direction. Inductive charging has come up with a biggest option which can develop and further expand electromobility.

electromobilityA research team at the Institute of Electrical Energy Conversion (IEW) of the University of Stuttgart, which is headed by Prof. Dr. Nejila Parspour, has been focusing for years on the inductive energy transfer, among other things, of e-vehicles.

The scientists at the IEW are researching the development of wireless electrical road systems with which commercial and passenger EVs can be charged without cables while driving or stationary. This is critical for increasing the range of electric vehicles. The efficiencies achieved with the systems developed at iew are over 95 percent.

Since public charging stations are still rare, inductive charging possibilities would also create more capacity – at relatively comparable costs. The e-vehicle could then be charged on the way to work and in the parking lot. It would no longer be necessary to plug the car in for charging all night, for example.

Prof. Dr. Nejila Parspour sees the greatest potential for further developments in analyzing the energy path. Contactless charging technology works using charging coils. For dynamic charging, i.e. while driving, induction coils will be put into the road surface. As soon as the vehicle is on top of them, the charging coils in the road are activated, and transfer electrical energy to the vehicle via a magnetic field. The scientific team around Prof. Parspour has already filed patent applications for different inventions in order to further advance the idea of inductive static and inductive dynamic charging. One of the most important inventions relates to positioning tolerance that allows for inductive charging regardless of the vehicle height and width.
