Mahle’s wireless charging positioning system DIPS (Differential Inductive Positioning System) has been chosen by SAE International as the global standard solution for wireless charging. Wireless (or inductive) charging of EVs is far more convenient for drivers and DIPS allows vehicles to be simply, reliably, and precisely aligned above a charging coil in the floor. By choosing DIPS, SAE International – the renowned non-profit association for the progress of mobility technologies – has closed the last gap in standardization of inductive charging. Mahle’s cross-manufacturer solution now paves the way for the comprehensive and rapid market launch of the viable alternative to wired charging for BEVs, EVs, and PHEVs.
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.
For the wireless charging of electric vehicles, all components relating to both the infrastructure and the vehicle side must be standardized. 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.
“The SAE’s decision in favor of our technology confirms the systems expertise of Mahle in electrification,” said Arnd Franz, Chairman of the Mahle Management Board and CEO. “This will be a strong impetus for e-mobility.”
