Full title and description

ISO 15118-1:2019 — Road vehicles — Vehicle to grid communication interface — Part 1: General information and use-case definition. This part of the ISO 15118 series provides general information, definitions, and use-case descriptions for the vehicle-to-grid communication interface used between electric vehicles (EVs) and charging stations to support smart charging, charging management, and energy exchange scenarios.

Abstract

ISO 15118-1:2019 establishes the high-level framework, terminology, and use-case definitions for communications between EVs and the Electric Vehicle Supply Equipment (EVSE). It explains the architecture, identifies stakeholders and actors, and outlines functional scenarios that later parts of ISO 15118 specify in technical detail. This document is intended to ensure consistent interpretation of concepts across the series and to support interoperable implementations of V2G-related services.

Scope

This document gives general information and defines use cases for the vehicle-to-grid communication interface. It describes the overall system architecture, identifies participating entities (for example, electric vehicle, EVSE, grid operator, and mobility operator), and specifies terminology, concepts, and high-level requirements that underpin the subsequent technical parts of ISO 15118. It does not prescribe protocol messages or detailed transport mechanisms; those are covered in other parts of the ISO 15118 series.

Key topics and requirements

• Definitions and terminology for vehicle-to-grid (V2G) communication
• Description of system architecture and roles (EV, EVSE, e-mobility service provider, grid operator, etc.)
• Identification of use cases for AC and DC charging, including smart charging and energy management scenarios
• High-level functional and non-functional requirements to guide implementers of ISO 15118 series
• Security and privacy considerations at a conceptual level (detailed security protocols are in other parts)
• Interoperability objectives and relationship to other standards and communications layers

Typical use and users

ISO 15118-1:2019 is used by standards engineers, product managers, and architects involved in electric vehicle charging systems, EVSE manufacturers, automotive OEMs, charge point operators, mobility service providers, and grid operators. It serves as a reference for defining system behavior and for aligning multiple stakeholders on common use cases before implementing protocol-specific parts of the ISO 15118 family.

Related standards

The ISO 15118 series (other parts) are directly related, notably ISO 15118-2 (network and application protocol requirements), ISO 15118-3 (physical and data link layers), ISO 15118-8/10 (semaphore and direct communication variants), and ISO 15118-20 (the newer consolidated revision covering V2G communication). Other related standards include IEC 61851 (charging system requirements) and OCPP (Open Charge Point Protocol) for charge station management.

FAQ

Q: What is this standard?

A: ISO 15118-1:2019 is Part 1 of the ISO 15118 series that provides general information, terminology, architecture description, and use-case definitions for vehicle-to-grid communication between electric vehicles and charging infrastructure.

Q: What does it cover?

A: It covers high-level concepts, stakeholders, system architecture, and use cases for AC and DC charging scenarios, along with conceptual security and interoperability considerations. It does not define message syntax or transport protocols; those are specified in other parts of the ISO 15118 family.

Q: Who typically uses it?

A: Automotive engineers, EVSE manufacturers, charging network operators, standards developers, and system integrators use it as a foundational reference to align on requirements and use cases before implementing detailed protocol parts.

Q: Is it current or superseded?

A: ISO 15118-1:2019 remains a published part of the ISO 15118 series. However, the ISO 15118 family has evolved, including a later consolidation (ISO 15118-20) that updates and extends the protocol definitions; implementers should check the full series for the most current technical specifications.

Q: Is it part of a series?

A: Yes. It is Part 1 of the ISO 15118 series. Other parts cover technical protocol details, physical layers, and security mechanisms (for example, ISO 15118-2, -3, -8, and the newer ISO 15118-20).

Q: What are the key keywords?

A: Vehicle-to-grid, V2G, ISO 15118, EV charging, EVSE, smart charging, interoperability, use cases, e-mobility.
