Scope:

SAE J2293 establishes requirements for Electric Vehicles (EV) and the off-board Electric Vehicle Supply Equipment (EVSE) used to transfer electrical energy to an EV from an Electric Utility Power System (Utility) in North America. This document defines, either directly or by reference, all characteristics of the total EV Energy Transfer System (EV-ETS) necessary to insure the functional interoperability of an EV and EVSE of the same physical system architecture. The ETS, regardless of architecture, is responsible for the conversion of AC electrical energy into DC electrical energy that can be used to charge the Storage Battery of an EV, as shown in Figure 1.

Rationale:

This stabilized Recommended Practice documents for reference the historical state of energy transfer systems and communications for electric vehicles as they existed in 2008, as defined in SAE J1772 (per published version 11-1-2001) for conductive charging and SAE J1773 (per published version 11-1-1999) for inductive charging.

SAE J1772 continues to be updated to reflect the latest in conductive charging technology. See the latest available version of J1772.

SAE J1773 remains unchanged for inductive charging.

Documentation for the now-emerging “wireless” inductive charging systems will be published when available.

Grid power quality for supplying charging systems is covered in SAE document series J2894.

For state-of-the-art documentation on charging communications, refer to the SAE documents in the series J2836, J2847, J2931, and J2953.
