This document specifies conformance tests in the form of an abstract test suite (ATS) for a system under test (SUT) implementing an electric-vehicle or supply-equipment communication controller (EVCC or SECC) with support for WLAN-based high-level communication (HLC) according to ISO 15118‑8 and against the background of ISO 15118-1. These conformance tests specify the testing of capabilities and behaviours of an SUT, as well as checking what is observed against the conformance requirements specified in ISO 15118‑8 and against what the implementer states the SUT implementation's capabilities are.
The capability tests within the ATS check that the observable capabilities of the SUT are in accordance with the static conformance requirements defined in ISO 15118‑8. The behaviour tests of the ATS examine an implementation as thoroughly as practical over the full range of dynamic conformance requirements defined in ISO 15118‑8 and within the capabilities of the SUT (see NOTE below).
A test architecture is described in correspondence to the ATS. The abstract test cases in this document are described leveraging this test architecture and are specified in descriptive tabular format for the ISO/OSI physical and data link layers (layers 1 and 2).
In terms of coverage, this document only covers normative sections and requirements in ISO 15118‑8. This document can additionally refer to specific tests for requirements on referenced standards (e.g. IEEE, or industry consortia standards, like WiFi Alliance) as long as they are relevant in terms of conformance for implementations according to ISO 15118‑8. However, it is explicitly not intended to widen the scope of this conformance specification to such external standards, if it is not technically necessary for the purpose of conformance testing for ISO 15118‑8. Furthermore, the conformance tests specified in this document do not include the assessment of performance nor robustness or reliability of an implementation. They cannot provide judgments on the physical realization of abstract service primitives, how a system is implemented, how it provides any requested service, nor the environment of the protocol implementation. Furthermore, the abstract test cases defined in this document only consider the communication protocol and the system's behaviour defined ISO 15118‑8. The power flow between the EVSE and the EV is not considered.
NOTE Practical limitations make it impossible to define an exhaustive test suite, and economic considerations can restrict testing even further. Hence, the purpose of this document is to increase the probability that different implementations are able to interwork. This is achieved by verifying them by means of a protocol test suite, thereby increasing the confidence that each implementation conforms to the protocol specification. However, the specified protocol test suite cannot guarantee conformance to the specification since it detects errors rather than their absence. Thus, conformance to a test suite alone cannot guarantee interworking. Instead, it gives confidence that an implementation has the required capabilities and that its behaviour conforms consistently in representative instances of communication.

Le présent document spécifie les tests de conformité sous la forme d'une suite de tests abstraite (ATS) pour un système sous test (SUT) implémentant un contrôleur de communication de véhicule électrique (CCVE) ou d'infrastructure de recharge (CCIR) qui prend en charge la communication de haut niveau (CHN) basée sur un réseau local sans fil (WLAN) conformément à l'ISO 15118-8 et sur la base de l'ISO 15118-1. Ces tests de conformité spécifient les tests de capacités et de comportements d'un SUT, puis vérifient les résultats obtenus par rapport aux exigences de conformité définies dans l'ISO 15118-8 et aux capacités d'implémentation du SUT définies par l'implémenteur.
Les tests de capacités définis dans la suite de tests abstraite (ATS) vérifient que les capacités observables sur le SUT respectent les conditions de conformité statique définies dans l'ISO 15118-8. Les tests de comportement de la suite de tests abstraite (ATS) examinent en détail une implémentation donnée dans l'ensemble des conditions de conformité dynamique définies dans l'ISO 15118-8, ainsi que dans les limites des capacités du SUT (voir NOTE ci-après).
Une architecture de test est décrite sur la base de la suite de tests abstraite (ATS). Les tests élémentaires abstraits définis dans le présent document sont décrits sur la base de cette architecture de test et sont spécifiés sous la forme de tableaux descriptifs pour la couche ISO/OSI physique (couche 1) et la couche ISO/OSI liaison de données (couche 2).
Le présent document ne couvre que les sections normatives et les exigences de l'ISO 15118-8. Le présent document peut également renvoyer vers des tests spécifiques pour les exigences relatives aux normes citées (par exemple, les normes de l'IEEE ou des normes établies par des consortiums industriels, comme la Wi-Fi Alliance) sous réserve que ces tests présentent un intérêt pour la conformité des implémentations conformément à l'ISO 15118-8. Toutefois, le présent document n'a pas pour objet d'élargir le domaine d'application de cette spécification de conformité à de telles normes externes, si cela n'est pas techniquement nécessaire pour les tests de conformité conformément à l'ISO 15118-8. En outre, les tests de conformité spécifiés dans le présent document n'incluent pas l'évaluation des performances, de la robustesse ou de la fiabilité d'une implémentation. Ces tests ne peuvent pas évaluer l'implémentation physique des primitives de services abstraites, la manière dont est implémenté un système, la manière dont celui-ci fournit un service demandé, ni l'environnement d'implémentation du protocole. Par ailleurs, les tests élémentaires abstraits définis dans le présent document couvrent uniquement le protocole de communication et le comportement du système définis par l'ISO 15118-8. Le flux de puissance transitant entre l'IRVE et le VE n'est pas pris en compte.
NOTE En raison de limites techniques, il n'est pas possible de définir une suite de tests exhaustive, à cela s'ajoutent des motifs d'ordre budgétaire qui peuvent également restreindre les tests. Le présent document a donc pour but d'augmenter la probabilité que différentes implémentations puissent fonctionner de manière interopérable. Pour vérifier ces implémentations, une suite de tests de protocole est ainsi spécifiée afin de garantir la conformité de chaque implémentation à la spécification du protocole. Cependant, la suite de tests de protocole spécifiée ne peut pas garantir la conformité d'une implém

Ta dokument določa preskuse skladnosti v obliki abstraktnih preskuševalnih nizov (ATS) za sistem za preskušanje (SUT), ki uporablja komunikacijski krmilnik električnega vozila ali opreme za napajanje (EVCC ali SECC) s podporo za komunikacijo na visoki ravni (HLC) na osnovi WLAN v skladu s standardom ISO 15118-8 in na podlagi standarda ISO 15118-1. Ti preskusi skladnosti določajo preskušanje zmogljivosti in delovanja sistema za preskušanje, pa tudi preverjanje ugotovitev s primerjavo z zahtevami glede skladnosti, določenimi v standardu ISO 15118-8, ter z navedbami izvajalca glede zmogljivosti izvajanja sistema za preskušanje.
Preskusi zmogljivosti znotraj abstraktnega preskuševalnega niza preverjajo, ali so opazne zmogljivosti sistema za preskušanje skladne z zahtevami glede statične skladnosti, določenimi v standardu ISO 15118-8. Preskusi delovanja znotraj abstraktnega preskuševalnega niza preverjajo izvajanje tako temeljito, kot je praktično mogoče, na podlagi polnega razpona zahtev glede dinamične skladnosti, določenih v standardu ISO 15118-8, in znotraj zmogljivosti sistema za preskušanje (glej OPOMBO spodaj).
Testna arhitektura je opisana ob upoštevanju sistema za preskušanje. Abstraktni preskusni primeri v tem dokumentu so opisani na podlagi te preskusne arhitekture ter so podani v opisni tabelarični obliki za fizično plast in podatkovno povezovalno plast ISO/OSI (plasti 1 in 2).
Ta dokument zajema samo normativne razdelke in zahteve v standardu ISO 15118‑8. Dokument lahko dodatno zajema posebne preskuse za zahteve referenčnih standardov (npr. IEEE ali skupni standardi konzorcijev, npr. zavezništvo WiFi) pod pogojem, da so ti ustrezni v smislu skladnosti za implementacije v skladu s standardom ISO 15118‑8. Vendar pa ni izrecno namenjen širjenju področja uporabe te specifikacije skladnosti na take zunanje standarde, če to ni tehnično potrebno za namene preskušanja skladnosti v skladu s standardom ISO 15118‑8. Poleg tega preskusi skladnosti, opisani v tem dokumentu, ne zajemajo ocenjevanja učinkovitosti niti robustnosti ali zanesljivosti implementacije. Ne morejo zagotoviti presoje glede fizične realizacije primitivov abstraktnih storitev, kako je sistem implementiran, kako zagotavlja katero koli zahtevano storitev, niti glede okolja implementacije protokola. Poleg tega abstraktni preskusni primeri, opredeljeni v tem dokumentu, upoštevajo samo komunikacijski protokol in delovanje sistema, kot je določeno v standardu ISO 15118‑8. Pretok energije med opremo za napajanje električnega vozila in električnim vozilom ni upoštevan.
General Information
Overview
EN ISO 15118-9:2023 (ISO 15118-9:2022) defines an abstract test suite (ATS) for wireless vehicle-to-grid (V2G) communication focusing on the physical and data link layers (ISO/OSI Layers 1 and 2). The standard specifies conformance tests for systems under test (SUT) implementing an Electric Vehicle Communication Controller (EVCC) or Supply Equipment Communication Controller (SECC) that support WLAN-based high-level communication (HLC) as defined in ISO 15118-8. Tests are described in a structured, tabular format and supported by a described test architecture.
Key topics and technical requirements
- Abstract Test Suite (ATS): Provides capability and behaviour tests to verify observable SUT capabilities against the static and dynamic conformance requirements in ISO 15118-8.
- Test architecture: Defines platform adapters, SUT adapter interfaces, codecs and test system components to execute the ATS.
- Physical & Data Link Layer focus: Tests target ISO/OSI Layer 1 (radio/bit transmission) and Layer 2 (data link/frame handling) for WLAN-based HLC.
- Capability tests (PICS-related): Verify declared, static features of an implementation match observed behaviour.
- Behaviour tests (PIXIT-related): Exercise dynamic protocol requirements within the SUT’s declared capabilities to check runtime behaviour.
- Test definitions & identifiers: Structured conventions for test suite identifiers, modules, test cases, verdicts and test profiles to support repeatable conformance testing.
- Scope limits: Explicitly excludes performance, robustness, reliability, environmental factors, power-flow assessment (EVSE ↔ EV) and exhaustive coverage. The ATS increases confidence in conformance but does not guarantee interoperability.
Practical applications and users
- EV and EVSE manufacturers: Validate WLAN-based V2G stack implementations (EVCC/SECC) against ISO 15118-8 requirements.
- Conformance and certification labs: Use ATS to create repeatable test campaigns for wireless physical/data link layer conformance.
- Test tool vendors: Implement the described test architecture, platform adapters and test case templates for automated conformance testing.
- Standards and interoperability consortia: Leverage the ATS as a prerequisite for downstream interoperability testing and certification programs.
- System integrators: Confirm that the communication controller behaviour aligns with declared capabilities before field deployment.
Related standards
- ISO 15118-8: High-level communication (HLC) specification - primary normative reference for test requirements.
- ISO 15118-1: General background and system context for vehicle-to-grid interfaces.
- IEEE / Wi-Fi Alliance and industry specs: May be referenced where relevant for WLAN-specific requirements, but ISO 15118-9 does not extend conformance scope to external standards unless technically necessary.
This standard is essential for teams implementing or testing wireless V2G communication stacks who need structured, repeatable conformance testing at the PHY and data link layers.

ISO 15118-9:2022(E)
Introduction
Resulting from the wireless physical and data link layer requirements defined in ISO 15118-8, a
corresponding set of abstract test cases is necessary to verify the conformance of implementations.
This document, therefore, defines a conformance test suite for the wireless physical and data link layer
protocols in order to derive a common and agreed basis for conformance tests. The resulting test suite
is a prerequisite for downstream interoperability tests. Since interoperability furthermore involves
the actual application logic of an implementation, those tests are beyond the scope of this document.
Hence, this document focuses on the interface aspects and the corresponding requirements given in
ISO 15118-8 only.

Physical and data link layer conformance test for wireless
communication
1 Scope
This document specifies conformance tests in the form of an abstract test suite (ATS) for a system under
test (SUT) implementing an electric-vehicle or supply-equipment communication controller (EVCC or
SECC) with support for WLAN-based high-level communication (HLC) according to ISO 15118-8 and
against the background of ISO 15118-1. These conformance tests specify the testing of capabilities and
behaviours of an SUT, as well as checking what is observed against the conformance requirements
specified in ISO 15118-8 and against what the implementer states the SUT implementation's capabilities
are.
The capability tests within the ATS check that the observable capabilities of the SUT are in accordance
with the static conformance requirements defined in ISO 15118-8. The behaviour tests of the ATS
examine an implementation as thoroughly as practical over the full range of dynamic conformance
requirements defined in ISO 15118-8 and within the capabilities of the SUT (see NOTE below).
A test architecture is described in correspondence to the ATS. The abstract test cases in this document
are described leveraging this test architecture and are specified in descriptive tabular format for the
ISO/OSI physical and data link layers (layers 1 and 2).
In terms of coverage, this document only covers normative sections and requirements in ISO 15118-8.
This document can additionally refer to specific tests for requirements on referenced standards (e.g.
IEEE, or industry consortia standards, like WiFi Alliance) as long as they are relevant in terms of
conformance for implementations according to ISO 15118-8. However, it is explicitly not intended to
widen the scope of this conformance specification to such external standards, if it is not technically
necessary for the purpose of conformance testing for ISO 15118-8. Furthermore, the conformance tests
specified in this document do not include the assessment of performance nor robustness or reliability
of an implementation. They cannot provide judgments on the physical realization of abstract service
primitives, how a system is implemented, how it provides any requested service, nor the environment
of the protocol implementation. Furthermore, the abstract test cases defined in this document only
consider the communication protocol and the system's behaviour defined ISO 15118-8. The power flow
between the EVSE and the EV is not considered.
NOTE Practical limitations make it impossible to define an exhaustive test suite, and economic considerations
can restrict testing even further. Hence, the purpose of this document is to increase the probability that different
implementations are able to interwork. This is achieved by verifying them by means of a protocol test suite,
thereby increasing the confidence that each implementation conforms to the protocol specification. However,
the specified protocol test suite cannot guarantee conformance to the specification since it detects errors rather
than their absence. Thus, conformance to a test suite alone cannot guarantee interworking. Instead, it gives
confidence that an implementation has the required capabilities and that its behaviour conforms consistently in
representative instances of communication.

3.1
abstract test case
complete and independent specification of the actions required to achieve a specific test purpose (3.25),
defined at the level of abstraction of a particular abstract test method, starting in a stable testing state
and ending in a stable testing state and optionally involves one or more consecutive or concurrent
connections
Note 1 to entry: The specification should be complete in the sense that it is sufficient to enable a test verdict
(3.29) to be assigned unambiguously to each potentially observable test outcome (i.e. sequence of test events).
Note 2 to entry: The specification should be independent in the sense that it should be possible to execute the
derived executable test case (3.7) in isolation from other such test cases (i.e. the specification should always
include the possibility of starting and finishing in the 'idle' state).

5.2 Test system description
TTCN-3 is used in this document to define/specify the test system architecture and test suite
conventions, where applicable. TTCN-3 is, however, not mandatory for the implementation of a
conformance test system according to this document.
[V2G9-001] The implementers of conformance tests shall verify that the test purposes implemented
in their executable test cases are identical to the abstract test cases described in this
document.
NOTE In this document, test cases are not programmatically specified in TTNC-3 core language. This will be
revisited for the next edition of the document.
6 Test architecture reference model
6.1 General information
Figure 1 provides an overview of the test architecture for this document. The following subclauses
define the interface requirements for platform and SUT adapters (see 6.2, 6.3) as well as the codecs (see
6.4). The test suite is defined in detail in the remainder of this document.
Figure 1 — Test architecture reference model
6.2 Platform adapter interface
The platform adapter within the test system is responsible for timers and external functions. Besides
means for timers, which are typically provided as part of the test framework, no external functions are
defined for this document.
ISO 15118-9:2022(E)
[V2G9-002] The platform adapter of the test system shall implement the TriPlatformPA and the
TriPlatformTE interfaces as defined in ETSI ES 201 873-5 V4.9.1:2022, 6.5.3.
6.3 SUT adapter interfaces
The SUT adapter within the test system adapts the TTCN-3 communication operations to the SUT based
on an abstract test system interface and implements the real test system interface. It is responsible
of propagating message requests and procedure-based calls from the test execution (see Figure 1) to
the SUT, and of notifying the test execution of any received test events by appending them to its port
queues.
[V2G9-003] Any SUT adapter of the test system shall implement the TriCommunicationSA and the
TriCommunicationTE interfaces as defined in ETSI ES 201 873-5 V4.9.1:2022, 6.5.2.
NOTE 1 The actual implementation of these adapters is out of scope of this document.
[V2G9-004] The ISO 15118-8 SUT adapter of the test system shall send/receive the encoded MAC
frame format to/from the SUT as defined in IEEE 802.11-2012, section 8.
NOTE 2 For association support according to ISO 15118-8 the management frames according to IEEE 802.11-
2012, section 8.3.3 are used and embedded in the frame body field of the MAC frame format.
[V2G9-005] The wireless communication module of the ISO 15118-8 SUT adapter of the test system
shall be certified by WiFi Alliance ('Wi-Fi CERTIFIED n').
The majority of requirements in ISO 15118-8 are based on IEEE 802.11n. WiFi Alliance certification is
therefore required for the ISO 15118-8 SUT adapter in order to ensure the test system complies with
IEEE 802.11n.
[V2G9-006] In case SUT is a STAUT, the ISO 15118-8 SUT adapter of the test system shall support
operation at both the 2,4 GHz and 5 GHz frequency bands in parallel (simultaneous dual
band support).
[V2G9-007] The wireless communication module of the ISO 15118-8 SUT adapter of the test system
shall at least support all allowed channels per frequency band that are applicable for
the SUT according to ISO 15118-8:2020, Tables 1, 2, and Annex D.
NOTE 3 Depending on the target market of the SUT, not all the channels listed in ISO 15118-8:2020, Tables 1
and 2 are allowed to be used due to national regulation.
NOTE 4 A collection of national regulations in usage of the U-NII band channels is listed in ISO 15118-8:2020,
Annex D.
[V2G9-008] The ISO 15118-8 SUT adapter of the test system shall support active and passive scan-
ning procedure according to IEEE 802.11-2012.
6.4 Codecs
A codec is responsible for the external encoding and decoding of TTCN-3 values into bit strings suitable
to be sent to the SUT. The test execution (TE) determines which codec shall be used and passes the
TTCN-3 data to the appropriate encoder to obtain the encoded data. Received data is decoded in this
entity by using the appropriate decoder, which translates the received data into TTCN-3 values cf.
ETSI ES 201 873-5 that can be matched against expected values or templates.
[V2G9-009] All codecs in this document shall implement the TCI-CD interface as defined in ETSI ES
201 873-6 V4.13.1:2022, 7.3.2.
ISO 15118-9:2022(E)
NOTE 1 For conformance testing in this document, the IEEE 802.11n codec (see Figure 1) is used to encode or
decode messages consumable by the tester into bit strings consumable by the SUT.
NOTE 2 The exact implementation of the IEEE 802.11n codec is out of scope of this document.
[V2G9-010] The ISO 15118-8 codec shall encode message values of the test system into correspond-
ing MAC frames consumable by the SUT as defined in ISO 15118-8:2020, 7.2.6 and 7.3.5
and IEEE 802.11-2012.
[V2G9-011] The ISO 15118-8 codec shall decode MAC frames as defined in ISO 15118-8:2020, 7.2.6
and 7.3.5 and IEEE 802.11-2012 into message values consumable by the test system.
7 Test suite conventions
7.1 General information
This clause defines all conventions that are relevant for conformance tests of SUTs implementing
ISO 15118-8.
7.2 Test suite structure (TSS)
A test suite is a complete set of test cases, possibly combined into groups or modules, that are necessary
to perform conformance testing for a given SUT.
Each executable test case stimulates the SUT with specific inputs and the reactions are observed
and evaluated. Depending on the test purpose different pre-conditions and post-conditions shall be
considered for the formulation of the test behaviour. The pre-conditions, post-conditions as well as test
behaviours are encapsulated into individual functions and stored within separate modules. Thus, a
complete test case is composed by the actual test behaviour enveloped by pre- and post-conditions. The
corresponding grouping of functions can therefore be assigned to the lowest abstract hierarchical level
(see Figure 2). The test cases are defined on the second level.
ISO 15118-9:2022(E)
Figure 2 — General overview of the test suite structure (TSS)
The test profile is a collection of self-contained test cases as well as PICS (see 7.3.3) and PIXIT (see 7.3.4)
in order to represent a given use case. The selection is based on the use cases of the ISO 15118 series
and its corresponding requirements.
Hence, the test suite structure (TSS) is segmented into subgroups defined according to ISO 15118 use
cases for conformance testing. Table 1 shows these subgroups, which are used for the organization of
the test case specifications as well as for the test suite identifiers (see 7.4 for detail).

7.3 Test profiles
This subclause defines test profiles for conformance with ISO 15118-8. A test profile consists of a test
configuration as well as a selection and assignment of PICS/PIXIT. Depending on the test configuration
a set of test components and ports are defined. The test profile furthermore includes a test group
defining the set of relevant test cases and the sequence in which they are executed in order to perform
a conformance test for a given use case.
ISO 15118-9:2022(E)
7.3.1 Test configurations
The test configuration reflects various ISO 15118 scenarios. The main entities for the system under test
(SUT) are:
— electric vehicle communication controller (EVCC),
— supply equipment communication controller (SECC).
The combination of entities and additionally used test components are grouped by test configuration
IDs (CF_Part_ID). Table 2 shows the test configurations for this document.

Frequently Asked Questions
EN ISO 15118-9:2023 is a standard published by the European Committee for Standardization (CEN). Its full title is "Road vehicles - Vehicle to grid communication interface - Part 9: Physical and data link layer conformance test for wireless communication (ISO 15118-9:2022)". This standard covers: This document specifies conformance tests in the form of an abstract test suite (ATS) for a system under test (SUT) implementing an electric-vehicle or supply-equipment communication controller (EVCC or SECC) with support for WLAN-based high-level communication (HLC) according to ISO 15118‑8 and against the background of ISO 15118-1. These conformance tests specify the testing of capabilities and behaviours of an SUT, as well as checking what is observed against the conformance requirements specified in ISO 15118‑8 and against what the implementer states the SUT implementation's capabilities are. The capability tests within the ATS check that the observable capabilities of the SUT are in accordance with the static conformance requirements defined in ISO 15118‑8. The behaviour tests of the ATS examine an implementation as thoroughly as practical over the full range of dynamic conformance requirements defined in ISO 15118‑8 and within the capabilities of the SUT (see NOTE below). A test architecture is described in correspondence to the ATS. The abstract test cases in this document are described leveraging this test architecture and are specified in descriptive tabular format for the ISO/OSI physical and data link layers (layers 1 and 2). In terms of coverage, this document only covers normative sections and requirements in ISO 15118‑8. This document can additionally refer to specific tests for requirements on referenced standards (e.g. IEEE, or industry consortia standards, like WiFi Alliance) as long as they are relevant in terms of conformance for implementations according to ISO 15118‑8. However, it is explicitly not intended to widen the scope of this conformance specification to such external standards, if it is not technically necessary for the purpose of conformance testing for ISO 15118‑8. Furthermore, the conformance tests specified in this document do not include the assessment of performance nor robustness or reliability of an implementation. They cannot provide judgments on the physical realization of abstract service primitives, how a system is implemented, how it provides any requested service, nor the environment of the protocol implementation. Furthermore, the abstract test cases defined in this document only consider the communication protocol and the system's behaviour defined ISO 15118‑8. The power flow between the EVSE and the EV is not considered. NOTE Practical limitations make it impossible to define an exhaustive test suite, and economic considerations can restrict testing even further. Hence, the purpose of this document is to increase the probability that different implementations are able to interwork. This is achieved by verifying them by means of a protocol test suite, thereby increasing the confidence that each implementation conforms to the protocol specification. However, the specified protocol test suite cannot guarantee conformance to the specification since it detects errors rather than their absence. Thus, conformance to a test suite alone cannot guarantee interworking. Instead, it gives confidence that an implementation has the required capabilities and that its behaviour conforms consistently in representative instances of communication.

Die Norm EN ISO 15118-9:2023, tituliert "Road vehicles - Vehicle to grid communication interface - Part 9: Physical and data link layer conformance test for wireless communication", stellt ein wichtiges Dokument im Bereich der Elektrofahrzeugkommunikation dar. Ihr Hauptfokus liegt auf der Spezifikation von Konformitätstests in Form einer abstrakten Testsuite (ATS) für Systeme, die einen Kommunikationscontroller für Elektrofahrzeuge (EVCC) oder Ladegeräte (SECC) implementieren und WLAN-basierte Hochkommunikation (HLC) gemäß ISO 15118-8 unterstützen. Die Stärken dieser Norm liegen in ihrer detaillierten Strukturierung von Tests, die sowohl die Fähigkeiten als auch die Verhaltensweisen eines Systems im Test (SUT) überprüfen. Diese Tests sind darauf ausgerichtet, sicherzustellen, dass die beobachtbaren Fähigkeiten des SUT den statischen Konformitätsanforderungen entsprechen, die in ISO 15118-8 definiert sind. Darüber hinaus untersucht die Norm dynamische Konformitätsanforderungen und bietet somit eine umfassende Analyse der Implementierung. Ein weiterer relevanter Aspekt der EN ISO 15118-9:2023 ist die Beschreibung einer Testarchitektur, die den Rahmen für die abstrakten Testfälle bereitstellt. Diese Testfälle sind in einer klaren und beschreibenden tabellarischen Form für die physikalischen und datalink-Schichten (Schichten 1 und 2) der ISO/OSI-Referenzarchitektur spezifiziert. Achtung sollte jedoch darauf gelegt werden, dass das Dokument nur normative Abschnitte und Anforderungen aus ISO 15118-8 abdeckt und keine Leistungs- oder Robustheitsbewertungen der Implementierungen vornimmt. Die Relevanz dieser Norm ist besonders in der heutigen Zeit zu erkennen, da sie darauf abzielt, die Interoperabilität unterschiedlicher Implementierungen zu fördern. Sie erhöht die Wahrscheinlichkeit, dass diese Systeme nahtlos zusammenarbeiten, was für die Entwicklung eines funktionierenden Netzwerks von Elektrofahrzeug-ladeinfrastruktur von entscheidender Bedeutung ist. Obwohl die Testsuite keine absolute Garantie für die Konformität bietet, vermittelt sie das Vertrauen, dass die Implementierungen die erforderlichen Fähigkeiten besitzen und sich konsistent in repräsentativen Kommunikationsszenarien verhalten. Insgesamt stellt die EN ISO 15118-9:2023 eine wertvolle Richtlinie für die Entwicklung und Prüfung von Systemen dar, die im Bereich Elektrofahrzeuge agieren. Ihre sorgfältige Konzeptionierung und der Fokus auf die Einhaltung von Konformitätsanforderungen machen sie zu einem unverzichtbaren Dokument für die Branche.
La norme SIST EN ISO 15118-9:2023 se distingue par la rigueur de son approche dans la définition des tests de conformité pour les systèmes de communication entre véhicules électriques et équipements d'alimentation (EVCC ou SECC). Son domaine d'application est clair et précis, portant spécifiquement sur la vérification des capacités et des comportements des systèmes en relation avec les exigences normatives établies dans ISO 15118-8 et dans le contexte d’ISO 15118-1. Un des points forts de cette norme réside dans sa capacité à offrir une suite de tests abstraite (ATS) qui facilite l'évaluation des systèmes sous test (SUT). Les tests de capacités définis vérifient que les fonctionnalités observables des SUT correspondent aux exigences statiques de ISO 15118-8, tandis que les tests de comportement engagent une analyse exhaustive des exigences dynamiques, garantissant ainsi une couverture substantielle des différents scénarios d'interaction. La norme propose une architecture de test bien définie, structurant les cas de tests abstraits dans un format tabulaire descriptif qui facilite leur compréhension et leur mise en œuvre. Ce format contribue à une meilleure interprétation des sections physiques et de liaison de données (couches 1 et 2), ce qui renforce son utilité dans des applications pratiques. En termes de pertinence, la norme SIST EN ISO 15118-9:2023 répond à un besoin crucial dans l'écosystème en pleine expansion des véhicules électriques, où la communication sans fil entre le véhicule et l'équipement d'alimentation devient de plus en plus prévalente. Son exclusion explicite de l'évaluation des performances, de la robustesse et de la fiabilité des implémentations souligne son objectif spécifique d'assurer la conformité du protocole sans s'aventurer dans des considérations techniques non nécessaires, ce qui permet de se concentrer pleinement sur les interactions conformes au protocole. En somme, cette norme est un outil essentiel pour garantir l’interopérabilité et la cohérence des implémentations dans le domaine de la communication entre véhicules « Vehicle to grid », favorisant ainsi un environnement propice au développement de technologies avancées dans le secteur de la mobilité électrique.
The standard EN ISO 15118-9:2023 provides a comprehensive framework for conformance testing within the vehicle-to-grid communication ecosystem, focusing specifically on the physical and data link layer conformance tests for wireless communication. Its scope is precisely defined, covering the abstract test suite (ATS) for systems that implement an electric vehicle communication controller (EVCC) or supply equipment communication controller (SECC) compliant with ISO 15118-8. This is critical as it ensures that the necessary communication protocols enable interoperability among various electric vehicle (EV) and charging infrastructure systems. One of the significant strengths of this standard lies in its rigorous capability and behavior testing. The ATS facilitates a structured approach to determine whether the observable capabilities of a system under test (SUT) align with the static requirements of ISO 15118-8. Additionally, the behavior tests provided within the ATS offer a practical examination of dynamic conformance requirements, allowing for a thorough assessment of how the SUT performs during various scenarios. This dual approach enhances the reliability of communication protocols and promotes confidence in system performance. Another key element of EN ISO 15118-9:2023 is its focus on maintaining a clear connection to existing standards without broadening its application to external norms unnecessarily. It supports specific references to standards such as IEEE and WiFi Alliance where relevant for conformance yet remains tightly bound to the requirements of ISO 15118-8. This ensures that the standard remains focused and applicable for implementations specifically addressing the vehicle-to-grid communications. Moreover, the test architecture detailed in the standard reinforces the clarity and applicability of the test cases, organized in a user-friendly tabular format corresponding to the ISO/OSI model. This structure enhances usability, enabling implementers to find pertinent information easily and apply it effectively in their testing regimes. Despite acknowledging practical limitations in fully exhaustive testing, EN ISO 15118-9:2023 aims to increase the likelihood of successful interworking between different implementations. While it cannot guarantee conformance or performance on its own, it fosters an environment of trust and consistency across implementations by verifying basic capabilities and behaviors as outlined in the standard. In summary, EN ISO 15118-9:2023 is a pivotal standard for those involved in the EV market, facilitating robust and reliable vehicle-to-grid communications through thorough conformance testing. Its focused scope, structured methodology, and emphasis on interoperability make it a valuable resource for stakeholders aiming to ensure compliance with the evolving electrical vehicle protocols.
EN ISO 15118-9:2023に関するレビューとして、この規格は、電気自動車と供給設備間のコミュニケーションに焦点を当てた重要なドキュメントです。この標準の範囲は、電気自動車（EV）または供給機器コミュニケーションコントローラー（EVCCまたはSECC）を実装するためのシステムに対する準拠テストを指定しています。これにより、ISO 15118-8に基づくWLANを使用した高レベルコミュニケーション（HLC）をサポートします。 本規格の強みは、抽象テストスイート（ATS）を通じて、システムの能力と挙動をしっかりとテストできる点です。これにより、ISO 15118-8で定義された静的準拠要件との観察可能な能力の整合性をチェックします。また、動的準拠要件に対する実装を徹底的に調査するためのビヘイビアテストも含まれており、これはEVCとSECC間の通信の信頼性向上に寄与します。 この文書が特に重要なのは、テストアーキテクチャと抽象テストケースを明確に定義している点です。これにより、物理層およびデータリンク層におけるコミュニケーションプロトコルの実装を評価する際の基準が提供されます。ただし、ISO 15118-8に基づく準拠テストの目的において、他の外部基準を広げる意図はありません。これにより、実装のパフォーマンスや堅牢性、信頼性の評価は含まれていないことが明示されています。 この標準は、異なる実装が相互運用できる可能性を高めることを目的としており、プロトコルテストスイートを通じて、各実装がプロトコル仕様に準拠していることへの信頼性を提供します。重要なのは、準拠テストスイートにより、エラーを検出することができるものの、仕様への完全な準拠を保証するものではない点です。そのため、異なる実装間の相互運用性を確保するためには、加えて他の検証手法が必要となることが示唆されています。 EN ISO 15118-9:2023は、電気自動車における先進的な通信技術の標準化を支援する重要な文書であり、持続可能な交通システムの発展に寄与することが期待されます。
표준 EN ISO 15118-9:2023은 전기 차량과 공급 장비 간의 통신 인터페이스를 정의하며, 물리적 및 데이터 링크 계층의 적합성 테스트를 위한 문서입니다. 이 표준의 주요 범위는 전기 차량 통신 제어기(EVCC)와 공급 장비 통신 제어기(SECC)의 무선 통신 능력을 확인하는 데 초점을 맞추고 있습니다. ISO 15118-8에 규정된 고수준 통신(HLC) 지원을 통해 시스템의 역량 및 동작을 평가하는 데 필요한 검사를 제시합니다. 이 문서는 추상 테스트 수트(ATS)를 통해 시스템의 능력과 동작을 확인하는 적합성 테스트를 제시합니다. ATS 내의 기능 및 행동 테스트는 ISO 15118-8에서 정의된 정적 및 동적 적합성 요구 사항에 기반하여 수행됩니다. 이로 인해 다양한 구현체들이 상호 운용할 수 있는 확률을 높이며, 테스트 아키텍처를 기반으로 한 추상 테스트 케이스들은 문서 내에서 명확히 설명되어 있습니다. 표준의 강점 중 하나는 테스트의 범위가 ISO 15118-8의 규범 섹션 및 요구 사항으로 한정되어 있어, 명확한 기준에 기반한 검사가 이루어진다는 점입니다. 또한, 구현자의 주장을 기반으로 시스템의 적합성을 검증함으로써, 상호 운용성에 대한 신뢰를 증대시킵니다. 그러나, 특정 외부 표준(예: IEEE, WiFi Alliance 등)과의 적합성에 대한 검사는 기술적으로 필요하지 않은 한 확장되지 않도록 명시되어 있습니다. 이에 따라, 성능이나 신뢰성, 안정성 평가를 포함하지 않으며, 물리적 구현의 실체나 프로토콜 구현의 환경에 대한 판단을 제공하지 않습니다. 결과적으로, EN ISO 15118-9:2023 표준은 전기 차량 통신 시스템의 효과적인 테스트 및 검증을 통해 상호 운용성을 촉진하고, 각 구현체가 요구되는 기능을 갖추고 일관된 행동을 보인다는 신뢰를 높여주는 중요한 역할을 합니다.
