Full title and description

Communication networks and systems for power utility automation - Part 90-8: Object model for E-mobility (IEC TR 61850-90-8:2016). This technical report describes an object model that maps E‑Mobility domain standards (electric vehicles and electric vehicle supply equipment) onto the IEC 61850 power‑utility automation data model to promote safety and interoperability between EV/EVSE and power‑system automation.

Abstract

IEC TR 61850-90-8:2016 demonstrates how IEC 61850‑7‑420 can be used to represent essential elements of E‑Mobility standards (including IEC 62196, IEC 61851 and ISO/IEC 15118) within the IEC 61850 information and logical node framework. The report provides object definitions, data attributes and modelling guidance to support integration of electric vehicle charging processes with power‑system automation. The focus is on modelling charging (vehicle-to-grid charging processes and related control/monitoring) to achieve interoperability; bidirectional/discharging use cases are noted as out of scope pending future standardization.

Scope

The report provides an object model and modelling rules showing how IEC 61850‑7‑420 (the distributed energy resources logical nodes) can be extended or applied to cover the main concepts and data needed for E‑Mobility charging systems. It maps EV/EVSE concepts and messages from standards such as IEC 62196 (vehicle connectors), IEC 61851 (charging systems) and ISO/IEC 15118 (vehicle‑to‑grid communications) into IEC 61850 logical nodes, data objects and services so that charging equipment and control systems can interoperate with power‑utility automation. The document concentrates on charging processes; discharging (grid‑support from vehicle batteries) is noted as out of scope until corresponding EV standards are available or updated.

Key topics and requirements

• Object model mapping between IEC 61850 (notably 7‑420) and E‑Mobility domain standards (IEC 62196, IEC 61851, ISO/IEC 15118).
• Definition and recommendations for logical nodes and data objects representing EV, EVSE and charging session attributes.
• Guidance for representing charging states, power/energy measurements, charging schedules, tariff and metering data within IEC 61850 models.
• Interoperability considerations for secure exchange of EV/EVSE information with utility automation systems.
• Normative and informative references that vendors and integrators should consult when implementing the object model.
• Notes on future extensions (for example, vehicle‑to‑grid/discharging and LVDC topics) and backward compatibility with IEC 61850 editions.

Typical use and users

Used by utilities, distribution system operators, charging station manufacturers, EVSE vendors, system integrators, software developers, testing and certification laboratories, and standards bodies. Typical applications include modelling EV charging points and sessions inside substation and distribution automation systems, integrating charging management into energy management and SCADA systems, and designing interoperable EV‑to‑grid interfaces.

Related standards

Key related publications include IEC 61850 series (especially IEC 61850‑7‑420 and IEC 61850‑7‑4), IEC 61851 (electric vehicle conductive charging systems), IEC 62196 (connectors/plugs), ISO/IEC 15118 (vehicle‑grid communication), and other technical specifications and guidance on EV metering, LVDC and grid integration. The report also references power‑system operational guidance and interoperability documents used by utilities and industry groups.

FAQ

Q: What is this standard?

A: IEC TR 61850‑90‑8:2016 is a technical report that defines an object model to map E‑Mobility (electric vehicle and EV supply equipment) concepts into the IEC 61850 power‑utility automation framework to enable interoperable charging integration.

Q: What does it cover?

A: It covers modelling rules, logical‑node/data‑object recommendations and guidance for representing charging processes, measurements and related attributes from EV/EVSE standards within IEC 61850. The focus is on charging use cases; vehicle discharging/grid‑support is identified as out of scope pending complementary EV standard work.

Q: Who typically uses it?

A: Utilities, distribution system operators, charging station and EVSE manufacturers, systems integrators, software vendors, and test/certification bodies implementing or verifying interoperability between EV charging infrastructure and power‑system automation.

Q: Is it current or superseded?

A: The report was published on 7 April 2016 (Edition 1.0). It is a technical report intended to guide implementations and was given a stability/maintenance horizon by the publisher; users should check with the IEC or their national standards body for any newer editions, amendments or incorporation of its content into later editions of IEC 61850 (for example updates to IEC 61850‑7‑420).

Q: Is it part of a series?

A: Yes — it is part of the IEC 61850 family (Communication networks and systems for power utility automation). The “90‑x” parts are technical reports and application‑oriented extensions that sit alongside the core parts such as 7‑4 and 7‑420.

Q: What are the key keywords?

A: E‑Mobility, EV, EVSE, IEC 61850, logical nodes, object model, charging, interoperability, ISO/IEC 15118, IEC 61851, IEC 62196.
