Full title and description

STB UNE-EN ISO 15118-1:2019 — Road vehicles — Vehicle to grid communication interface — Part 1: General information and use‑case definition. This part of ISO 15118 gives terms and definitions, high‑level communication (HLC) requirements and use‑case definitions for conductive and wireless communication between the electric vehicle communication controller (EVCC) and the supply equipment communication controller (SECC), and provides a common overview to support vehicle‑to‑grid and grid‑to‑vehicle energy transfer, identification/association, charging/discharging control, payment, load levelling, cybersecurity and privacy.

Abstract

Part 1 of ISO 15118 serves as the conceptual and use‑case foundation for the rest of the ISO 15118 series. It does not specify lower‑layer data link protocols but defines the HLC concepts, terminology, general requirements and typical scenarios (manual/automatic connection, conductive and wireless power transfer, vehicle charging and vehicle‑to‑grid energy return). The document is intended to enable interoperable EV–SE (EV supply equipment) interfaces across e‑mobility actors.

Scope

This part specifies terms and definitions, general requirements and use cases for high‑level communications (HLC) between the EV communication controller (EVCC) and the supply equipment communication controller (SECC) for both conductive and wireless charging. It applies to power transfer from EV supply equipment to the EV battery and from the EV battery to the supply equipment (vehicle‑to‑grid / V2G) for supplying homes, loads or the grid, and provides guidance on aspects that influence identification, association, charge/discharge control and optimisation, payment, load levelling, cybersecurity and privacy. It is intended as the conceptual foundation for other parts of ISO 15118 (e.g., message definition and protocol mappings).

Key topics and requirements

• Definitions and terminology for the ISO 15118 family (EVCC, SECC, HLC, use cases).
• Use‑case definitions covering manual and automatic connection, conductive and wireless scenarios, charging and V2G energy exchange.
• High‑level requirements for identification, authentication, association and session management between EV and charging equipment.
• Requirements and considerations for charge/discharge control, load levelling and energy optimisation.
• Overview of payment and contractual interactions related to charging sessions (high‑level).
• Cybersecurity and privacy considerations at the HLC level (architectural guidance; detailed security mechanisms are covered in other parts of the series).
• Intended interoperability goals to support message‑level specifications in ISO 15118‑2 and subsequent parts.

Typical use and users

Typical users include EV OEMs, charging station manufacturers, EV charge network operators, energy utilities, e‑mobility service providers, systems integrators and test laboratories. The standard is used during product design, interoperability testing, system architecture definition, procurement and regulatory compliance activities related to EV charging and V2G functionality.

Related standards

ISO 15118‑1 is part of the ISO 15118 series and is normally used together with ISO 15118‑2 (message sets and protocol mappings), ISO 15118‑20 (newer message/profile work), and with complementary standards such as IEC 61851 (EV conductive charging), IEC 61980 (wireless power transfer), and relevant national/adopted EN/UNE versions. Implementers also cross‑reference applicable IEC, ISO and industry documents for cybersecurity, communications and metering.

FAQ

Q: What is this standard?

A: ISO 15118‑1:2019 (nationally published as UNE‑EN ISO 15118‑1:2019) is the General Information and Use‑Case Definition part of the ISO 15118 series, defining terminology, high‑level requirements and use cases for EV–grid communications.

Q: What does it cover?

A: It covers conceptual definitions, general requirements and a set of use cases for conductive and wireless HLC between an electric vehicle’s communication controller (EVCC) and supply equipment (SECC), including charging, V2G energy flow, identification/association, payment concepts, load management and privacy/cybersecurity considerations. It does not define low‑level message encodings or specific link‑layer protocols (those are in other parts of the series).

Q: Who typically uses it?

A: EV manufacturers, charging‑station vendors, charge‑point operators, utilities, e‑mobility service providers and test houses use this part as a conceptual reference when implementing or validating ISO 15118‑based solutions.

Q: Is it current or superseded?

A: ISO 15118‑1:2019 is the 2019 edition (Edition 2). The ISO bibliographic record shows the 2019 edition as the current published edition; national adoptions (UNE‑EN) were published later in 2019. The ISO catalogue indicates the standard is on the formal ISO lifecycle and has been the basis for later parts of the series; users should check the ISO catalogue or their national body for any confirmations, amendments or newer related parts (for example ISO 15118‑20 and subsequent revisions).

Q: Is it part of a series?

A: Yes — ISO 15118‑1 is Part 1 of the ISO 15118 series (vehicle‑to‑grid communication interface); it is designed to be read with other parts such as ISO 15118‑2 (message sets) and ISO 15118‑20 (newer message/profile specifications), plus complementary IEC/EN documents for the physical charging system.

Q: What are the key keywords?

A: vehicle-to-grid, V2G, EV charging, vehicle communication controller (EVCC), supply equipment communication controller (SECC), high‑level communication (HLC), interoperability, use cases, cybersecurity, load levelling.
