The company signed a letter committing to work with German automotive producer MAHLE in order to bring home wireless electric vehicle charging. The plans include technical collaboration and joint interoperability testing.

MAHLE and Siemens intend to work together in the field inductive charging of electric vehicles. Both companies have signed an agreement to this effect.

“Wireless charging of electric vehicles is emerging as a major market for the future. It will make driving much more enjoyable, as drivers won’t need to use cables or connectors. This is an essential requirement for autonomous mobility. The transfer efficiency of wireless, inductive charging is comparable to plug-in systems,” stated Stefan Perras, head of pre-development and innovation for charging infrastructure at Siemens AG.

The planned cooperation between German companies includes coordinated standardization efforts within the relevant pre-standardization or standardization bodies. It is hoped that gaps will be closed to ensure interoperability between charging infrastructure and vehicles.

A close exchange of ideas is also planned to develop an inductive charging solution for electric vehicles. MAHLE will contribute its many years as an automotive supplier, and Siemens its expertise on the charging infrastructure.

Both parties plan to conduct extensive cross-testing and interoperability between the charging equipment on a vehicle (secondary coil), and the charging infrastructure.

This will allow for technical improvements, validation of inductive charging systems and ensure interoperability. Some of the testing will take place as part of publicly funded programs.

MAHLE’s latest announcement is this one. In recent years, MAHLE has intensified its efforts in wireless charging development. These include two projects that were funded by the German Federal Ministry for Economic Affairs and Climate Action.

One project aims at developing a cross-manufacturer vehicle inductive charging system. A standard method for measuring electromagnetic compatibility inductive systems is being developed in the second.
