Scope
This document covers the general physical, electrical, functional, testing, and performance requirements for conductive power transfer, primarily for vehicles using a conductive ACD connection capable of transferring DC power. It defines conductive power transfer methods, including the infrastructure electrical contact interface, the vehicle connection interface, the electrical characteristics of the DC supply, and the communication system. It also covers the functional and dimensional requirements for the vehicle connection interface and supply equipment interface. New editions of the documents shall be backwards compatible with the older editions. There are also sub-documents which are identified by a SAE J3105/1, SAE J3105/2, and SAE J3105/3. These will be specific requirements for a specific interface defined in the sub-document.

Rationale
The original document was initially intended for on-route charging and not necessarily in a depot setting with vehicles charging adjacent to one another. The significant change in this current update is that an RFID tag has been added including the logic to ensure that the correct vehicle is paired with the correct infrastructure prior to enabing charge in close proximity. The vehicle height requirements were modified to correct an oversight. Y-cap requirements were changed to reflect a better technical solution. Sequential charging logic was added to allow for it. All timing diagrams were updated for the new subjects. A new appendix, Appendix I, is included to help clarify the additions required to support sequential charging and RFID/EVCCID pairing. A new appendix, Appendix J, is added to document the test procedure for validating the new sections of the document. Appendix I was used by the committee to verify that the system described and controls do work. A week in October was spent at the Heliox facility with more than 12 experts ranging from OEMs, charging OEMs, control OEMs, and others. Finally, miscellaneous grammar and typos were corrected.

Issuing Committee
The Hybrid Technical Standards Committee reports to the Powertrain Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to the field of hybrid vehicle technology. The following topics are within the scope of this committee's work: safety aspects of hybrid systems in vehicles, test procedures to establish the performance of hybrid systems and components, nomenclature, as well as vehicle interface and serviceability requirements Participants in the SAE Hybrid Technical Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.

listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
