DIPS, an innovative technology by Mahle, facilitates automatic alignment and connection with the charging point as an EV approaches, improving the efficiency of the wireless charging process.
DIPS operates on a magnetic field basis, enabling seamless and accurate positioning of the vehicle over the charging pad, even under challenging conditions like snow or wet leaves. This technology is not only applicable to manual parking but also enhances the capabilities of autonomously parking vehicles by providing necessary positioning instructions.
The charging pad, referred to as the "ground assembly" by SAE, generates a low-frequency magnetic field, which is detected by the "vehicle assembly" for precise positioning. Looking ahead, Mahle, in partnership with Electreon Wireless, is also setting standards for dynamic inductive charging, allowing EVs to charge while in motion.
The SAE J2954 standard promises up to 93% efficiency in charging processes, marking a significant advancement in inductive charging technology. Mahle, with partners Siemens and Witricity, is at the forefront of developing comprehensive wireless charging solutions for EVs.
SAE International, representing over 128,000 engineers and technology experts across various industries, envisions EV charging to be as straightforward as parking and leaving the vehicle. Jesse Schneider, Chairman of the SAE Wireless Power Transfer Task Force, notes that the adoption of DIPS completes the standard for efficient, automated, and all-weather wireless charging and parking, addressing a crucial gap in the commercialization of wireless EV charging.
