Full title and description

ISO 15118-5:2018 — Road vehicles — Vehicle to grid communication interface — Part 5: Physical layer and data link layer conformance test. This part of the ISO 15118 series specifies an Abstract Test Suite (ATS) and a test architecture for conformance testing of the physical (OSI Layer 1) and data link (OSI Layer 2) layers for EV/EVSE communication, focusing on PLC-based High Level Communication (HLC) and Basic Signaling as defined in ISO 15118-3.

Abstract

ISO 15118-5:2018 defines conformance tests (capability and behavior tests) for a System Under Test (SUT) implementing an Electric Vehicle Communication Controller (EVCC) or Supply Equipment Communication Controller (SECC). The document describes a test architecture and expresses test cases in TTCN-3 for the ISO/OSI physical and data link layers. Tests verify observable capabilities and dynamic behavior against the normative requirements of ISO 15118-3; performance, robustness, reliability and power-flow are outside the scope. The standard includes a corrected English version published in May 2018 and was confirmed after systematic review in 2023.

Scope

The standard specifies conformance test procedures (an Abstract Test Suite) for implementations of ISO 15118‑3 at the physical and data link layers. It covers capability tests to check static conformance requirements and behavior tests to examine dynamic requirements within the SUT's capabilities. The conformance tests are intended to increase interoperability confidence between different implementations of EVCC and SECC using PLC-based HLC and Basic Signaling. It does not assess power transfer, overall system implementation choices, or non-functional properties such as performance, robustness or reliability.

Key topics and requirements

• Abstract Test Suite (ATS) for physical (Layer 1) and data link (Layer 2) conformance.
• Capability tests to validate static conformance requirements from ISO 15118‑3.
• Behavior tests to validate dynamic protocol behavior within observed capabilities.
• Test architecture and test case specification expressed in TTCN-3 Core Language.
• Coverage limited to normative requirements of ISO 15118‑3; optional inclusion of referenced-standard tests only when necessary for conformance.
• Explicit exclusion of power-flow testing and assessments of implementation internals, performance or robustness.
• Interdependencies with ISO 15118-4 (conformance tests for network and application layers) due to OSI cross-layer behavior (e.g., sleep mode).

Typical use and users

Primary users include test laboratories, certification bodies, EV and EVSE (charging station) manufacturers, protocol and firmware developers, QA and validation teams, and systems integrators who need to verify that physical and data link layer implementations conform to ISO 15118‑3. The standard is used to produce repeatable test suites, implement automated TTCN-3 test harnesses, and support interoperability and certification programs (e.g., Plug & Charge readiness and V2G communication interoperability).

Related standards

ISO 15118-5 is part of the ISO 15118 series. Closely related documents include ISO 15118-3 (physical and data link layer requirements), ISO 15118-4 (network and application layer conformance test), ISO 15118-1 and -2 (general information and network/application requirements), and later/adjacent parts of the series (including ISO 15118-20). Other related standards and specifications often referenced in testing and implementation include IEC/EN standards for charging infrastructure (for example IEC 61851), industry specifications such as DIN SPEC 70121, and TTCN-3 language specifications used to express test cases.

FAQ

Q: What is this standard?

A: ISO 15118-5:2018 defines conformance tests (an Abstract Test Suite) and a test architecture for the physical and data link layers of the ISO 15118 vehicle-to-grid communication interface, focusing on PLC-based communication between EV and charging equipment.

Q: What does it cover?

A: It covers capability and behavior tests for EVCC and SECC implementations against the normative requirements of ISO 15118‑3, test case specification in TTCN-3, and a test architecture for Layers 1 and 2. It does not cover network/application layer tests (those are in ISO 15118‑4), power-flow, performance, robustness or implementation internals.

Q: Who typically uses it?

A: Test laboratories, certification bodies, EV and charging-station manufacturers, firmware and protocol developers, and QA/validation teams use it to verify conformance and support interoperability and certification efforts.

Q: Is it current or superseded?

A: ISO 15118-5:2018 is Edition 1 (published March 2018 with a corrected English version in May 2018). The publication was systematically reviewed and confirmed in 2023, so this edition remains current as the confirmed international standard.

Q: Is it part of a series?

A: Yes. It is one part of the ISO 15118 series (Vehicle to grid communication interface). Other parts cover general use cases, network and application requirements, conformance testing for higher layers, and wireless/single-pair variants (e.g., ISO 15118‑1, -2, -3, -4, -20, etc.).

Q: What are the key keywords?

A: Key keywords include ISO 15118, conformance test, EVCC, SECC, PLC, HLC, Basic Signaling, TTCN-3, physical layer, data link layer, interoperability, Plug & Charge, V2G.
