8、al standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internatio
9、nal organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended
10、 for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

16、facturers to make a very significant effort to reduce the energy consumption of their vehicles. They are presently developing vehicles partly or completely propelled by electric energy. Those vehicles will reduce the dependency on oil, improve global energy efficiency and reduce the total CO 2emissi
17、ons for road transportation if the electricity is produced from renewable sources. To charge the batteries of such vehicles, specific charging infrastructure is required. Much of the standardization work on dimensional and electrical specifications of the charging infrastructure and the vehicle inte
18、rface is already treated in the relevant ISO or IEC groups. However, the question of information transfer between the vehicle, the local installation and the grid has not been treated sufficiently. Such communication is beneficial for the optimization of energy resources and energy production system
19、s as vehicles can recharge at the most economic or most energy-efficient instants. It is also required to develop efficient and convenient payment systems in order to cover the resulting micro-payments. The necessar y communication channel may ser ve in the future to contribute to the stabilization
20、of the electrical grid as well as to support additional information services required to operate electric vehicles efficiently. ISO 2013 All rights reserved v Road vehicles Vehicle to grid communication interface Part 1: Gener al information and use-case definition 1 Scope ISO 15118 specifies the co
21、mmunication between Electric Vehicles (EV), including Battery Electric Vehicles and Plug-In Hybrid Electric Vehicles, and the Electric Vehicle Supply Equipment (EVSE). As the communication parts of this generic equipment are the Electric Vehicle Communication Controller (EVCC) and the Supply Equipme
22、nt Communication Controller (SECC), ISO 15118 describes the communication between these components. Although ISO 15118 is oriented to the charging of electric road vehicles, it is open for other vehicles as well. This part of ISO 15118 specifies terms and definitions, general requirements and use ca
23、ses as the basis for the other parts of ISO 15118. It provides a general overview and a common understanding of aspects influencing the charge process, payment and load levelling. ISO 15118 does not specify the vehicle internal communication between battery and charging equipment and the communicati
24、on of the SECC to other actors and equipment (beside some dedicated message elements related to the charging). All connections beyond the SECC, and the method of message exchanging are considered to be out of the scope as specific use cases. NOTE 1 Electric road vehicles specifically are vehicles in
25、 categories M (used for carriage of passengers) and N (used for carriage of goods) (compare ECE/TR ANS/WP.29/78 ev.2). This does not prevent vehicles in other categories from adopting ISO 15118 as well. NOTE 2 This part of ISO 15118 is destined to orientate the message set of ISO 15118-2. The absenc
26、e of any par t icular use case in this part of ISO 15118 does not imply that it shall not put into practice, with the required messages. NOTE 3 This part of ISO 15118 and ISO 15118-2 are designed to work independent of data transfer medium used. However, this series of documents are made for fitting
27、 the specified data link layers in the corresponding documents in this series. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated
