Information exchange for electric vehicle charging roaming service - Part 2: Use cases

The Standard specifies roaming use cases of information exchange between EV Charge Service Providers (CSP), Charging Station Operators (CSOs) and Clearing House platforms through roaming endpoints. The elementary use cases defined in this document of IEC 63119-2 are designed to support the user to have access to the EV supply equipment which doesn’t belong to the Home-CSP. IEC 63119 series are applicable to high-level communication involved in information exchange/interaction between different CSPs, as well as between a CSP and CSO with or without Clearing House platform through the roaming endpoint. IEC 63119 series do not specify the communication either between Charging Station (CS) and Charging Station Operator (CSO) or between EV and CS.

Échange d'informations pour le service d'itinérance de la recharge des véhicules électriques - Partie 2: Cas d'utilisation

L'IEC 63119-2:2022 spécifie les cas d'utilisation en itinérance de l'échange d'informations entre les prestataires de services de recharge (CSP, Charging Service Providers) de VE, les opérateurs de bornes de charge (CSO, Charging Station Operators) et les plateformes d'échanges de données par le biais d'un nœud final d'itinérance. Les cas d'utilisation élémentaires définis dans le présent document sont conçus pour aider l'utilisateur à accéder au système d'alimentation pour VE qui n'appartient pas au CSP contractuel. L'IEC 63119 (toutes les parties) s'applique aux communications de haut niveau dans le cadre des échanges d'informations/interactions entre les différents CSP, mais aussi entre un CSP et un CSO avec ou sans plateforme d'échange de données par le biais du nœud final d'itinérance. L'IEC 63119 (toutes les parties) ne spécifie pas la communication entre la borne de charge (CS, Charging Station) et l'opérateur de bornes de charge (CSO) ni entre le VE et la CS.

Izmenjava informacij za gostovanje storitev napajanja električnih vozil - 2. del: Primeri uporabe (IEC 63119-2:2022)

Standard določa primere uporabe gostovanja pri izmenjavi informacij med ponudniki storitev polnjenja električnih vozil (CSP), operaterji polnilnih postaj (CSO) in platformami Clearing House prek končnih točk gostovanja. Primeri osnovne uporabe, opredeljeni v tem dokumentu standarda IEC 63119-2, so zasnovani tako, da so uporabniku v pomoč pri dostopu do opreme za napajanje električnih vozil, ki ne spada v Home-CSP.
Skupina standardov IEC 63119 se uporablja za komunikacijo na visoki ravni, ki poteka pri izmenjavi podatkov/interakcijami med različnimi ponudniki storitev napajanja, pa tudi med ponudniki storitev napajanja in operaterji polnilnih postaj s platformami Clearing House prek končnih točk gostovanja ali brez njih.
Skupina standardov IEC 63119 ne določa komunikacije med polnilno postajo (CS) in operaterjem polnilne postaje (CSO) ali med električnim vozilom in polnilno postajo.
