SAE International‘s Wireless Power Transfer & Alignment Taskforce has selected Electreon, a global wireless Electric Vehicle (EV) charging company, and MAHLE’s wireless positioning methodology for the global SAE J2954 standard.
With rapid growth in EV adoption, solely relying on plug-in charging is falling short of enabling the convenient and efficient powering of EVs. Electreon’s wireless charging can charge EVs quickly and safely, eliminating range anxiety, and lowering the total costs of EV ownership while reducing battery capacity needs.
This makes it one of the most environmentally sustainable, scalable, and compelling available charging solutions. A missing piece of this puzzle is formalizing universal standards for interoperable, safe, automated wireless charging.
Electreon’s wireless power transfer system, as the selected field-validated alignment methodology for SAE J2954, enables reliable wireless charging through coils embedded in roads and parking spots. This standardized inductive charging technology promises a seamless, automated charging experience to greatly accelerate mass EV adoption.
The newly announced SAE J2954 standard establishes Electreon’s DIPS as the global industry’s wireless charging alignment methodology. By standardizing the DIPS technology for wireless power transfer, the J2954 protocol enables seamless automated charging across public and private infrastructure.
DIPS works by using a magnetic field between the ground assembly (in-road charging coil) and the vehicle assembly (vehicle receiver) to guide precise alignment for charging. The new updated standard, scheduled to be published in 2024, will include specifications for fine alignment, pairing/authentication, and alignment checks between the in-road coil and receiver.
With operational projects in Germany, Italy, Sweden, Israel, and the US, Electreon already runs dozens of public real-world wireless charging projects in which it has demonstrated multiple vehicles charging both dynamically as they drive over the electrified road, and while parked. Electreon has spearheaded the efforts in developing this global standard for dynamic wireless charging and has incorporated this solution which is now part of the standard in its projects.
The updated SAE J2954 standard solves a major barrier on the path to scalable wireless EV charging deployments.
“Electreon is a global leader in wireless charging and has already proven its implementation with numerous OEMs for both static and dynamic wireless charging cases,” stated Dr. Andreas Wendt co-chair of the J2954-3 Power Transfer working group, and Regional Director of Electreon Germany GmbH. “Yet, this SAE certification for our alignment methodology for SAE J2954 is the official recognition of Electreon’s technical expertise at the highest global standard and will enable us to drive full-steam ahead with our automotive partnership integration strategies.”
