Full title and description

STB UNE-EN 61851-21-1-2017 AC-2017 — Electric vehicle conductive charging system — Part 21-1: Electric vehicle on-board charger — EMC requirements for conductive connection to an AC/DC supply. This document specifies electromagnetic compatibility (EMC) test requirements and test setups for on-board charging units (either as complete vehicles or as electronic sub-assemblies) when connected to a mains supply; an amendment/corrigendum (AC:2017) corrects editorial/technical items in the adopted text.

Abstract

IEC 61851-21-1:2017 (adopted as UNE-EN 61851-21-1:2017 in Spain and published with AC:2017 corrections) defines EMC emission and immunity requirements for electrically propelled road vehicles while connected to AC or DC supply in any charging mode. The part focuses exclusively on EMC testing (rather than other electrical tests), provides precise test configurations and introduces Annex material on artificial/asymmetric networks and integration of charging stations into test setups.

Scope

This part of IEC 61851 applies to on-board charging units of electrically propelled road vehicles (including battery electric vehicles and plug-in hybrids) when connected to AC or DC supplies and addresses EMC emission and immunity requirements for those on-board units in any charging mode. It does not apply to trolleybuses, rail vehicles, industrial trucks or vehicles designed primarily for off-road use (forestry, construction machines). The document defines required test setups, ports, limits and informative/normative annexes for artificial networks and integration of charging stations in test arrangements.

Key topics and requirements

• EMC emission and immunity test requirements for on-board EV charging units (conductive connection to AC/DC supply).
• Defined test setups and ports for conducted and radiated phenomena (including radiated RF fields, conducted disturbances, EFT/bursts, surge immunity and pulses on supply lines).
• Use of artificial networks and asymmetric artificial networks for realistic integration of charging stations into EMC tests (Annex A and related guidance).
• Clarification that this part addresses EMC only (other electrical/safety tests are covered in other parts of the IEC 61851 series).
• Applicability to testing either the complete vehicle (with on-board charger installed) or the electronic sub-assembly (ESA) level for on-board charging equipment.

Typical use and users

Manufacturers of electric vehicles and on-board chargers, EV component suppliers, test and certification laboratories, regulatory and homologation bodies, EV system integrators and charging-station manufacturers use this standard to verify EMC performance of on-board charging equipment and to ensure interoperability and compliance with regional/national EMC requirements.

Related standards

This part is one element of the IEC 61851 series. Relevant related documents include IEC 61851-1 (general requirements for EV conductive charging systems), IEC 61851-21-2 (EMC requirements for off-board charging equipment), and other parts of the EV charging family (for example IEC 61851-23/24/25 and associated connector/communication standards such as IEC 62196). Regional/adopted versions exist (EN/UNE-EN, BS EN, DS/EN, etc.).

FAQ

Q: What is this standard?

A: It is IEC 61851-21-1:2017, adopted regionally as UNE-EN 61851-21-1:2017 (with AC:2017 corrections noted) — a technical standard that defines EMC test requirements and setups for on-board electric vehicle charging equipment when connected to AC or DC supplies.

Q: What does it cover?

A: The standard covers EMC emission and immunity tests (conducted and radiated), test arrangements (including artificial network arrangements), ports and limits relevant to on-board chargers or on-board charging sub-assemblies while connected to the mains in any charging mode. It concentrates on EMC only; other electrical and safety requirements are covered in other IEC 61851 parts.

Q: Who typically uses it?

A: EV OEMs, on-board charger and power-electronics manufacturers, test laboratories, certification bodies, homologation authorities and integrators who need to prove EMC compliance of vehicle on-board charging equipment.

Q: Is it current or superseded?

A: IEC 61851-21-1:2017 is the first edition published by IEC on 19 June 2017 and remains the published edition; national/adopted versions (UNE-EN 61851-21-1:2017) and corrigenda/amendments (AC:2017) are available. The IEC webstore lists a stability date (indicative) for the publication; users should check their national standards body for any later amendments or national corrigenda.

Q: Is it part of a series?

A: Yes — it is part of the IEC 61851 series (conductive EV charging systems). Companion parts include IEC 61851-1 (general requirements), IEC 61851-21-2 (EMC for off-board equipment), IEC 61851-23/24/25 and others addressing DC charging, communications and related interfaces.

Q: What are the key keywords?
