Road vehicles - Vehicle to grid communication interface - Part 4: Network and application protocol conformance test (ISO 15118-4:2018)
ISO 15118-4:2018 specifies conformance tests in the form of an Abstract Test Suite (ATS) for a System Under Test (SUT) implementing an EVCC or SECC according to ISO 15118-2. These conformance tests specify the testing of capabilities and behaviors of an SUT as well as checking what is observed against the conformance requirements specified in ISO 15118-2 and against what the supplier 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 15118-2. The behavior tests of the ATS examine an implementation as thoroughly as is practical over the full range of dynamic conformance requirements defined in ISO 15118-2 and within the capabilities of the SUT (see NOTE).
A test architecture is described in correspondence to the ATS. The conformance test cases in this document are described leveraging this test architecture and are specified in TTCN-3 Core Language for ISO/OSI Network Layer (Layer 3) and above. The conformance test cases for the Data Link Layer (Layer 2) and Physical Layer (Layer 1) are described in ISO 15118-5. Test cases with overlapping scopes are explicitly detailed.
This document does not include specific tests of other standards referenced within ISO 15118-2, e.g. IETF RFCs. 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 test cases defined in this document only consider the communication protocol defined ISO 15118-2. Power flow between the EVSE and the EV is not considered.
NOTE 1 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. What it does do is give confidence that an implementation has the required capabilities and that its behavior conforms consistently in representative instances of communication.
NOTE 2 This document has some interdependencies to the conformance tests defined in ISO 15118-5 which result from ISO/OSI cross layer dependencies in the underlying protocol specification (e.g. for sleep mode)

Le présent document spécifie des tests de conformité sous la forme d'une suite de tests abstraits (ATS) pour un système à tester (SUT) implémentant un EVCC ou un SECC conformément à la norme ISO 15118-2. Ces tests de conformité spécifient le contrôle des capacités et des comportements d'un SUT ainsi que la vérification de ce qui est observé en comparaison des exigences de conformité spécifiées dans la norme ISO 15118-2 et en comparaison des capacités de l'implémentation du SUT formulées par le fournisseur.
Les tests de capacités compris dans l'ATS vérifient que les capacités observables du SUT sont conformes aux exigences de conformité statiques définies dans la norme ISO 15118-2. Les tests de comportement de l'ATS examinent une implémentation de la manière la plus approfondie possible sur l'ensemble de l'éventail des exigences de conformité dynamiques définies dans la norme ISO 15118-2 et dans les limites des capacités du SUT (voir NOTE).
Une architecture de test est décrite en rapport avec l'ATS. Dans le présent document, les cas de test de conformité sont décrits en s'appuyant sur cette architecture de test et sont spécifiés en langage noyau TTCN-3 pour la couche réseau (Couche 3) ISO/OSI et supérieures. Les cas de test de conformité pour la couche liaison de données (Couche 2) et la couche physique (Couche 1) sont décrits dans la norme ISO 15118-5. Des cas de test dont les domaines d'application se recoupent sont détaillés de manière explicite.
Le présent document n'inclut pas les tests spécifiques d'autres normes données en référence dans la norme ISO 15118-2, par ex., les RFC de l'IETF. En outre, les tests de conformité spécifiés dans le présent document n'incluent pas l'évaluation du rendement, de la robustesse ou encore de la fiabilité d'une implémentation. Ils ne peuvent servir à la formulation de jugements sur la réalisation physique de primitives de service abstraites, sur la manière dont un système est implémenté, sur la manière dont il fournit un quelconque service requis, ou sur l'environnement de l'implémentation du protocole. En outre, les cas de test définis dans le présent document prennent uniquement en considération le protocole de communication défini dans la norme ISO 15118-2. Le flux d'énergie entre l'EVSE et l'EV n'est pas pris en compte.
NOTE 1 Les limitations pratiques empêchent la définition d'une suite de tests exhaustive, et des considérations économiques peuvent restreindre le test encore davantage. Par conséquent, le présent document a pour but d'accroître la probabilité d'interopérabilité de différentes implémentations. Cela est réalisé en les vérifiant au moyen d'une suite de tests de protocole qui permet ainsi d'augmenter la certitude selon laquelle chaque implémentation est conforme à la spécification du protocole. Cependant, la suite de tests de protocole spécifiée ne peut garantir une conformité à la spécification étant donné qu'elle détecte les erreurs plutôt que leur absence. Par conséquent, la conformité d'une suite de tests ne peut garantir à elle seule une interopérabilité. En revanche, cela apporte la garantie qu'une implémentation présente les capacités requises et que son comportement est systématiquement conforme dans des instances représentatives de communication.
NOTE 2 Le présent document présente certaines interdépendances avec les tests de conformité définis dans la norme ISO 15118-5 qui découlent de dépendances inter-couches ISO/OSI dans la spécification du protocole sous-jacent
Cestna vozila - Komunikacijski vmesnik med vozilom in omrežjem - 4. del: Preskus skladnosti omrežja in aplikacijskega protokola (ISO 15118-4:2018)
Standard ISO 15118-4:2018 določa preskuse skladnosti v obliki niza abstraktnih preskusov (ATS) za sistem za preskušanje (SUT), ki uporablja komunikacijski krmilnik električnega vozila (EVCC) ali komunikacijski krmilnik opreme za napajanje (SECC) v skladu s standardom ISO 15118-2. 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 15118-2, ter z navedbami dobavitelja glede zmogljivosti izvajanja sistema za preskušanje.
Preskusi zmogljivosti znotraj niza abstraktnih preskusov preverjajo, ali so opazne zmogljivosti sistema za preskušanje skladne z zahtevami glede statične skladnosti, določenimi v standardu ISO 15118-2. Preskusi delovanja znotraj niza abstraktnih preskusov preverjajo izvajanje tako temeljito, kot je praktično mogoče, na podlagi polnega razpona zahtev glede dinamične skladnosti, določenih v standardu ISO 15118-2, in znotraj zmogljivosti sistema za preskušanje (glej OPOMBO).
Testna arhitektura je opisana ob upoštevanju sistema za preskušanje. Primeri preskusov skladnosti v tem dokumentu so opisani na podlagi te testne arhitekture in so podani v jedrnem jeziku TTCN-3 za omrežno plast ISO/OSI (plast 3) in višjo. Primeri preskusov skladnosti za podatkovno povezovalno plast (plast 2) in fizično plast (plast 1) so opisani v standardu ISO 15118-5. Preskusni primeri s prekrivajočimi se področji so izrecno opisani.
Ta dokument ne zajema posebnih preskusov iz drugih standardov, na katere se sklicuje znotraj standarda ISO 15118-2, npr. IETF RFC. 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 primeri preskusov, opredeljeni v tem dokumentu, upoštevajo samo komunikacijski protokol, določen v standardu ISO 15118-2. Pretok energije med opremo za napajanje električnega vozila in električnim vozilom ni upoštevan.
OPOMBA 1: Zaradi praktičnih omejitev je nemogoče definirati izčrpen niz preskusov, še dodatno pa lahko preskušanje omejijo ekonomski dejavniki. Tako je namen tega dokumenta povečati verjetnost za medsebojno delovanje različnih implementacij. To se doseže tako, da se te implementacije preverijo s sredstvi niza preskusov protokola, s čimer se poveča verjetnost, da je posamezna implementacija skladna s specifikacijo protokola. Vendar pa podani niz preskusov protokola ne more zajamčiti skladnosti s specifikacijo, saj zaznava napake in ne odsotnosti implementacij. Tako skladnost z nizom preskusov sama po sebi ne more zajamčiti medsebojnega delovanja. Na ta način se samo prepriča, da implementacija vključuje zahtevane zmogljivosti in da pri reprezentativnih primerih komunikacije deluje dosledno skladno.
OPOMBA 2: Ta dokument v določeni meri zajema medsebojno odvisnost s preskusi skladnosti, definiranimi v standardu ISO 15118-5, ki izhajajo iz medslojnih odvisnosti ISO/OSI v specifikaciji osnovnega protokola (npr. za način spanja).

Introduction
The first three parts of ISO 15118 describe the use cases and the technical specification of the Vehicle‐
to‐Grid Communication Interface which is intended for the optimized use of energy resources so that
electric road vehicles can recharge in the most economic or most energy efficient way. It is furthermore
required to develop efficient and convenient billing systems in order to cover the resulting micro‐
payments. The necessary communication channel may serve in the future to contribute to the
stabilization of the electrical grid as well as to support additional information services required to
operate electric vehicles efficiently and economically.
The complexity resulting from the network and application protocol requirements defined in the
second part of the standard requires a considerable amount of testing in order to enable
interoperability between independent implementations. This document therefore defines a
conformance test suite for the network and application layer protocols in order to derive a common and
agreed basis for conformance tests. The resulting test suite is a necessary 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 part two only.

Part 4: Network and application protocol conformance test
1 Scope
This document specifies conformance tests in the form of an Abstract Test Suite (ATS) for a System
Under Test (SUT) implementing an EVCC or SECC according to ISO 15118‐2. These conformance tests
specify the testing of capabilities and behaviors of an SUT as well as checking what is observed against
the conformance requirements specified in ISO 15118‐2 and against what the supplier 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 15118‐2. The behavior tests of the ATS
examine an implementation as thoroughly as is practical over the full range of dynamic conformance
requirements defined in ISO 15118‐2 and within the capabilities of the SUT (see NOTE).
A test architecture is described in correspondence to the ATS. The conformance test cases in this
document are described leveraging this test architecture and are specified in TTCN‐3 Core Language for
ISO/OSI Network Layer (Layer 3) and above. The conformance test cases for the Data Link Layer (Layer
2) and Physical Layer (Layer 1) are described in ISO 15118‐5. Test cases with overlapping scopes are
explicitly detailed.
This document does not include specific tests of other standards referenced within ISO 15118‐2, e.g.
IETF RFCs. 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 test cases defined in this document only consider the communication protocol defined ISO 15118‐2.
Power flow between the EVSE and the EV is not considered.
NOTE 1 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. What it does do is give
confidence that an implementation has the required capabilities and that its behavior conforms consistently in
representative instances of communication.
NOTE 2 This document has some interdependencies to the conformance tests defined in ISO 15118‐5 which
result from ISO/OSI cross layer dependencies in the underlying protocol specification (e.g. for sleep mode)

3.1
abstract test case
complete and independent specification of the actions required to achieve a specific test purpose
Note 1 to entry: This specification is 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 may involve one or more consecutive or
concurrent connections.
Note 2 to entry: The specification should be complete in the sense that it is sufficient to enable a test verdict to be
assigned unambiguously to each potentially observable test outcome (i.e. sequence of test events).
Note 3 to entry: The specification should be independent in the sense that it should be possible to execute the
derived executable test case in isolation from other such test cases (i.e. the specification should always include the
possibility of starting and finishing in the “idle” state).
Note 4 to entry: Compare with ITU‐T X.290.
3.2
abstract test suite
ATS
test suite composed of abstract test cases
Note 1 to entry: Compare with ITU‐T X.290.

3.3
black box testing
method of testing that examines the behavior of an SUT without considering the internal
implementation and structure of the SUT, thus relying on the SUT's open interface for testing
3.4
conformance requirements
conformance of a real system consisting of conformance to each requirement and conformance to the
set
Note 1 to entry: Set of interrelated requirements which together define the behavior of the system and its
communication. Conformance of a real system will, therefore, be expressed at two levels, conformance to each
individual requirement and conformance to the set. Applicable ISO 15118‐4 conformance tests include
requirements and transfer syntax requirements as far as they can be validated by black box testing.
