Utilizing a magnetic field, the Differential Inductive Positioning System (DIPS) automatically connects with the controlled charging point as an electric vehicle approaches it.
Mahle, a German Tier-1 automotive supplier, has developed an innovative vehicle positioning system that seamlessly aligns an electric vehicle (EV) with a wireless EV charger’s coil embedded in the ground. This system has been selected by SAE International, previously known as the Society of Automotive Engineers, as the global standard for wireless EV charging. This move by the prestigious non-profit organization, known for bringing together mobility professionals to foster safe, clean, and accessible mobility solutions, marks the completion of a decade-long gap in the standardization of inductive EV charging. Mahle’s universal solution is set to accelerate the widespread adoption of this efficient alternative to traditional wired charging for electric and hybrid vehicles.
Arnd Franz, Mahle’s CEO, asserts that SAE International’s endorsement of their technology validates Mahle’s expertise in the field of electrification and signifies a major push towards e-mobility.
The Differential Inductive Positioning System (DIPS) system operates on a magnetic field and automatically connects with the charging point as the EV nears it. An onboard navigation system aids the driver in positioning the vehicle precisely so that charging starts automatically.
DIPS is also engineered to function with autonomous parking vehicles, guiding the parking system for accurate positioning. This Mahle system ensures easy and consistent parking even in adverse conditions like snow or wet leaves.
Industry experts emphasize the need to standardize all elements involved in wireless EV charging, from infrastructure to vehicles, to guarantee compatibility across different manufacturers and facilitate the introducing of market-ready solutions. Mahle intends to offer its technology to the entire industry under a fair, reasonable, and non-discriminatory (FRAND) licensing model.
The versatility of DIPS is also expected to support future mobile applications, like charging through induction coils while driving, a standard co-developed with Electreon Wireless.
Mahle has strongly advocated wireless charging infrastructure for electric vehicles, viewing it as a convenient and viable option. The company collaborates closely with Siemens and Witricity in advancing the integrated system of charging infrastructure and automotive engineering, as stated by Dr Harald Straky, Head of Corporate Research and Advanced Engineering at Mahle.
