To shape future mobility and intelligent energy infrastructure, MAHLE and SIEMENS have committed to lead the development of inductive charging for electric vehicles. The wireless power transfer system is based on coil systems utilizing resonant coupling with impedance matching networks located on the vehicle and ground assembly sides. This wireless power transfer system facilitates transfer efficiencies of up to 92% with optimal positioning. The detection of living or foreign objects ensures safety. Successful standardization guarantees the compatibility of the vehicle and ground wireless charging assemblies produced by different manufacturers. The end user experiences convenient and reliable wireless charging due to the positioning system, which is robust to environmental influences. The full automation of the wireless power transfer system, without physical user interaction, enables charging of autonomous vehicle fleets and makes the acceptance of charging as part of everyday life obsolete.
The continuous power transfer of 11 kW has been demonstrated in a test vehicle in the laboratory and in a parking lot. To roll out inductive charging technology, ground assemblies will be installed in private, semi-public and public parking areas. MAHLE and SIEMENS are also developing wireless bi-directional power transfer capability to enable the use of the battery capacity of grid-friendly vehicles, as part of a sustainable energy infrastructure.
