SAE J2954 is a standard for wireless power transfer (WPT) for electric vehicles led by SAE International. It defines three classes of charging speed, WPT 1, 2 and 3, at a maximum of 3.7 kW, 7.7 kW and 11 kW, respectively. This makes it comparable to medium-speed wired charging standards like the common SAE J1772 system. A much more powerful WPT9 is being defined in J2954/2 for 500 kW charging for heavy-duty vehicles which have the room necessary to mount t… WebJan 17, 2024 · KIWI International Air Lines.
