J2954/3
The SAE J2954 standard establishes an industry-wide specification that defines acceptable criteria for Light Duty EVs and SAE RP J2954/2 establishes the same for Heavy Duty. SAE RP SAE J2954. SAE RP J2954/3 establishes interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for dynamic wireless power transfer (D-WPT) of both light and heavy duty plug-in electric vehicles. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels as SAE J2954/1 & SAE J2954/2 with some variations. A standard for WPT based on these charge levels enables selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging and ease of customer use. SAE J2954/3 addresses unidirectional charging, from grid to vehicle; bidirectional energy transfer may be evaluated for a future standard.
