Energy Transfer System for Electric Vehicles - Part 2: Communication Requirements and Network Architecture

Document Number: J2293/2
Date Published: July 2008

Issuing Committee:
Hybrid Committee

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. The different physical ETS system architectures are identified by the form of the energy that is transferred etween the EV and the EVSE, as shown in figure 2. It is possible for an EV and EVSE to support more than one architecture. This document does not contain all requirements related to EV energy transfer, as there are many aspects of an EV and EVSE that do not affect their interoperability. specifically, this document does not deal with the characteristics of the interface between the EVSE and the Utility, except to acknowledge the Utility as the source of energy to be transferred to the EV.many aspects of an EV and EVSE that do not affect their interoperability. specifically, this document does not deal with the characteristics of the interface between the EVSE and the Utility, except to acknowledge the Utmany aspects of an EV and EVSE that do not affect their interoperability. specifically, this document does not deal with the characteristics of the interface between the EVSE and the Utility, except to acknowledge the Utility as the source of energy to be transferred to the EV.many aspects of an EV and EVSE that do not affect their interoperability. specifically, this document does not deal with the characteristics of the interface between the EVSE and the Utility, except to acknowledge the Utility as the source of energy to be transferred to the EV.ility as the source of energy to be transferred to the EV.
