This document details one of the connections of the SAE J3105 document. The connections are referenced in the scope of the main document SAE J3105. SAE J3105/1 details the infrastructure-mounted pantograph, or cross-rail connection. All the common requirements are defined in the main document; the current document provides the details of the connection.
This document covers the connection interface relevant requirements for an electric vehicle power transfer system using a conductive ACD based on a cross-rail design. To allow interoperability for on-road vehicles (in particular, buses and coaches), one configuration is described in this document. Other configurations may be used for non-standard applications (for example, mining trucks or port vehicles).
Conductive automated connection devices (ACD) solutions are attractive to heavy-duty applications where downtime resulting from charge operations need to be minimized and the operator prefers to make the connection without leaving the operator's seat. The existing SAE charging standards do not address conductive ACD charging solutions that serve to promote all day operation of high capacity electric vehicles. The infrastructure-mounted pantograph is suitable for power transfer up to 600 kW with Level 1 and up to 1.2 MW for Level 2. It is hands-free, vertically engaged, and is positioned on the infrastructure above the vehicle.

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 ¿ vehicle interface and serviceability requirements Participants in the SAE Hybrid Technical Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.
* Redlines comparisons are available for those standards 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.
