IEC 63119-1 establishes a basis for the other parts of IEC 63119, specifying the terms and definitions, general description of the system model, classification, information exchange and security mechanisms for roaming between EV charge service providers (CSPs), charging station operators (CSOs) and clearinghouse platforms through roaming endpoints.
IEC 63119-1 is applicable to high-level communication involved in information exchange/interaction between different CSPs, as well as between a CSP and a CSO with or without a clearinghouse platform through the roaming endpoint.
IEC 63119-1 on information exchange for electric vehicle charging roaming service is useful for:
The information exchange of roaming focuses on actors between different CSPs, as well as between a CSP and CSO with or without clearing house platform through the roaming endpoint. The clearing house is an optional actor to complete the roaming functions, which can be completely or partially executed directly between different service providers.
IEC 63119-1 guideline provides roaming-related communication exchange to users and specifies the general relationship of roaming with the relevant technologies.
IEC 63119-1 also covers best industry guidance on classification of roaming service models. Roaming types are classified according to three basic modes: peer-to-peer or direct mode, clearing house mode, and mixed mode, depending on whether there is an intermediary to facilitate the roaming process as regards different types of roaming functions. The difference between the clearing house mode and the mixed mode is determined by the charging service module. To allow for a quicker response and an improved user experience, the mixed mode allows for direct communication between different roaming endpoints to initiate and control charging sessions.
