6、ms. SAE J2931 identifies the requirements and protocols, as various options are available to the consumer and utility. Battery Electric Vehicles (BEV) were developed several years ago and the connector, EVSE and analogue interface was described in SAE -DQGKDVEHHQXSGDWHGWREHWWHUPDWFK3OXJ -In Hybrid V
7、ehicle (PHEV) criteria. Utility companies are developing the smart grid communication and control system to balance this additional load with available distribution and several options will be available to the consumer. Plug-In Vehicle (PEV) and EVSE digital communication is required to insure the c
8、ustomer is able to roam and connector any PEV to any EVSE for these additional features. Considerably more manufacturers have entered the market PEVs and EVSEs with more BEV and PHEV combinations, and also offer a wide variety of EVSEs from 120V and 240V AC, plus DC charging where the EVSE includes
9、an off-board charger for faster rates. This market will continue to expand and change, and the customers need to connect and charge any PEV with any EVSE using their preferred communication medium and still interface with the local utility. FOREWORD The recent inception of the PEV (Plug-In Electric
10、Vehicle) and its related charging standards has brought a high level of concern regarding the interoperability between PEVs and related grid equipment. Because of the variation of charging standard implementation it is currently difficult to ensure that any PEV will be able to interface and communic
11、ate successfully with supply equipment or other grid devices available to consumers. 7RPHHWWKHQHHGVRI3(9RSHUDWRUVWKH3(9FKDUJLQJSURFHVVPXVWKDYHSOXJDQGSODLQWHURSHUDELOLWPHDQLQJWKDWany specific PEV and any related supply equipment must interface and communicate properly without special effort by the op
12、erator. The acceptance of the PEV as a supplement to fossil fuel vehicles is dependent on the interoperability, reliability and convenience of the charge process. In order to meet these criteria PEV charging standards must be sufficiently robust and must have a significant focus on achieving interop
13、erability.

SCOPE This SAE Recommended Practice J2953/1 establishes requirements and specification by which a specific Plug
22、-In Electric Vehicle (PEV) and Electric Vehicle Supply Equipment (EVSE) pair can be considered interoperable. The test procedures are further described in J2953/2. 1.1 Purpose This document assembles and clarifies the requirements for multiple levels of interoperability as defined in related PEV cha
23、rging standards (listed below). It provides support for charging systems which are developed according to SAE J1772 and may also implement the digital communication requirements within SAE J2836 and SAE J2847 standards. There is also support for SAE J2931 which identifies the vehicle to grid require
24、ments and protocols as various options are available to the consumer and utility. This document also functions as a tool for documenting interoperability issues and standards gaps that can be communicated to standards committees, ultimately leading to refining vehicle charging related SAE standards.
25、 1.2 Rational Analyzing the number of real world PEV EVSE combinations that show interoperability will give insight on the effectiveness of the vehicle charging related SAE standards in terms of interoperability. Using single component testing one can already see that there are inconsistencies betwe
26、en manufacture supply equipment and inconsistencies between manufacture Plug-In Electric Vehicles. Combining both components into a system allows one to discover how these inconsistencies can interact to afIHFWWKHVVWHPVDELOLWWRSHUIRUPFRUUHFWO 1.3 Revision Information: This first revision addresses i
