scope:

ISO 15118 specifies the communication between Electric Vehicles(EV), including Battery Electric Vehicles and Plug-In HybridElectric Vehicles, and the Electric Vehicle Supply Equipment(EVSE). As the communication parts of this generic equipment arethe Electric Vehicle Communication Controller (EVCC) and the SupplyEquipment Communication Controller (SECC), ISO 15118 describes thecommunication between these components. Although ISO 15118 isoriented to the charging of electric road vehicles, it is open forother vehicles as well. This part of ISO 15118 specifies terms anddefinitions, general requirements and use cases as the basis forthe other parts of ISO 15118. It provides a general overview and acommon understanding of aspects influencing the charge process,payment and load levelling. ISO 15118 does not specify the vehicleinternal communication between battery and charging equipment andthe communication of the SECC to other actors and equipment (besidesome dedicated message elements related to the charging). Allconnections beyond the SECC, and the method of message exchangingare considered to be out of the scope as specific use cases. NOTE 1Electric road vehicles specifically are vehicles in categories M(used for carriage of passengers) and N (used for carriage ofgoods) (compare ECE/TR ANS/WP.29/78 ev.2). This does not preventvehicles in other categories from adopting ISO 15118 as well. NOTE2 This part of ISO 15118 is destined to orientate the message setof ISO 15118-2. The absence of any particular use case in this partof ISO 15118 does not imply that it shall not put into practice,with the required messages. NOTE 3 This part of ISO 15118 and ISO15118-2 are designed to work independent of data transfer mediumused. However, this series of documents are made for fitting thespecified data link layers in the corresponding documents in thisseries.
