The standardization organization SAE International has selected Mahle Group's positioning system as a global standard solution for the wireless charging of electric vehicles. This decision represents a significant advancement in the standardization of inductive charging for electric cars.

"Mahle sets standards. The decision by the renowned SAE for our technology confirms Mahle's system expertise in electrification. This will be a strong impetus for e-mobility," said Arnd Franz, Chairman of the Group Management Board and CEO.

The Mahle positioning system, known as the Differential-Inductive-Positioning-System (DIPS), enables precise alignment of electric vehicles over a charging coil. This system uses a magnetic field to automatically connect with the charging point when the vehicle approaches it. A special display in the vehicle's dashboard assists drivers with accurate positioning, after which the charging process begins automatically. This applies to both manually driven and autonomously parking vehicles.

"With Siemens and Witricity, we have two strong partners by our side with whom we are jointly advancing the overall system of charging infrastructure and vehicle technology," said Dr. Harald Straky, Head of Central Corporate Research and Advanced Engineering at Mahle.

According to Mahle, the wide applicability of the system also enables future dynamic applications: charging via induction coils while driving. For this, Mahle – together with Electreon Wireless – has also formulated a standard.

The recognition by SAE International closes a ten-year gap in the standardization of inductive charging and marks an important step towards cross-manufacturer compatibility. According to Mahle, the company plans to offer its solution to the industry under fair, reasonable, and non-discriminatory (FRAND) terms, which promotes the wide implementation and rapid market introduction of this technology.
