Inductive charging of electric vehicles is much more convenient as there is no need to fiddle with cables or search for a charging station with a suitable plug.
Mahle has developed a positioning system called DIPS (Differential Inductive Positioning System) which SAE International, a developer of global technology standards, including the standardisation of the vehicle identification number, has now chosen as the global standard solution for wireless charging. The cross-manufacturer solution paves the way for the comprehensive and rapid market launch of an attractive alternative to wired charging for batteries and electric and hybrid vehicles.
“Mahle is setting standards” said Arnd Franz, Chairman of the Mahle Management Board and CEO. “The renowned SAE’s decision in favor of our technology confirms the systems expertise of Mahle in electrification as well. This will be a strong impetus for e-mobility.”
The DIPS is based on a magnetic field and automatically establishes a connection with the controlled charging point as the electric vehicle approaches. A special navigation system in the vehicle display supports the driver, and the car is soon in the ideal position. The charging process begins automatically. This also works with an autonomous parking vehicle, where the parking system receives the necessary positioning instructions instead of the driver. The Mahle positioning system means that the parking process can be carried out very easily and reproducibly in one go. This also applies to unfavourable environmental conditions such as snow cover or wet leaves on the bottom plate.
For the wireless charging of electric vehicles, all components relating to both the infrastructure and the vehicle side must be standardised. Only then can both the vehicle manufacturers and the infrastructure providers bring a solution to market that ensures compatibility regardless of the manufacturer. Mahle will make its solution accessible to the entire industry via a license model under FRAND (fair, reasonable, and non-discriminatory) conditions.
The broad applicability of the system will also enable mobile applications in the future, such as charging via induction coils while driving. Mahle has also formulated the standard for this together with Electreon Wireless.
In terms of charging infrastructure, Mahle has long relied on wireless charging, which is a convenient and promising alternative for electric vehicles.
“Siemens and Witricity are two strong partners at our side with whom we are jointly advancing the complete system of charging infrastructure and automotive engineering” said Dr. Harald Straky, Head of Corporate Research and Advanced Engineering at Mahle.
