Just as wireless charging is a boon to mobile phones, it will be a game changer for electric

German auto parts manufacturer Mahle reckons it has developed a positioning system that
allows an electric vehicle to be simply, reliably and precisely aligned above the charging
coil in the floor.

The Mahle positioning system DIPS (Differential Inductive Positioning System) represents
a paradigm shift in the field of e-mobility.

It 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 then begins automatically. This also works with
an autonomous parking vehicle, where the parking system receives the necessary
positioning instructions instead of the driver.

Thanks to the unique Mahle positioning system, the parking process can be carried out
very easily and reproducibly in one go. And it will also work in unfavourable environmental
conditions, such as snow or wet leaves on the bottom plate.

The cross-manufacturer solution from Mahle now paves the way for the comprehensive
and rapid market launch of this attractive alternative to wired charging for batteries and
electric and hybrid vehicles.

“Mahle is setting standards. The renowned SAE’s decision in favour of our technology
confirms the systems expertise of Mahle in electrification as well,” Mahle’s Arnd Franz

“This will be a strong impetus for e-mobility.”

SAE International has selected the Mahle positioning system as the global standard
solution for wireless charging. The organisation develops global technology standards,
including the standardization of the vehicle identification number. It boasts more than
128,000 engineers and technology experts from the aerospace, automotive and
commercial vehicle industries.
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,”
Mahle’s Dr Harald Straky said.
