IEC 61851-21-1:2017

Electric vehicle conductive charging system - Part 21-1 Electric vehicle on-board charger EMC requirements for conductive connection to AC/DC supply

IEC 61851-21-1:2017, together with IEC 61851-1:2010, gives requirements for conductive connection of an electric vehicle (EV) to an AC or DC supply. It applies only to on-board charging units either tested on the complete vehicle or tested on the charging system component level (ESA - electronic sub assembly).
This document covers the electromagnetic compatibility (EMC) requirements for electrically propelled vehicles in any charging mode while connected to the mains supply. This first edition, together with IEC 61851-21-2, cancels and replaces IEC 61851-21:2001. It constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61851‑21:2001:
a) this document addresses now only EMC tests instead of other electrical tests;
b) test setups are defined more precisely;
c) Annex A "Artificial networks, asymmetric artificial networks and integration of charging stations into the test setup" was added.

Système de charge conductive pour véhicules électriques - Partie 21-1: Exigences CEM relatives à la connexion conductive des chargeurs embarqués pour véhicules électriques à une alimentation en courant alternatif ou continu

L'IEC 61851-21-1:2017 , ainsi que l’IEC 61851-1:2010, spécifient les exigences relatives à la connexion conductive d’un véhicule électrique (VE) à une alimentation en courant alternatif ou continu. Elle ne s’applique qu’aux unités de charge embarquées soumises à essai soit sur le véhicule complet, soit au niveau des composants du système de charge (SEEE – sous-ensemble électrique/électronique).
Le présent document couvre les exigences de compatibilité électromagnétique (CEM) pour les véhicules à propulsion électrique, quel que soit le mode de charge, lorsqu’ils sont connectés au réseau électrique.
Il ne s’applique pas aux trolleybus, véhicules ferroviaires, camions et véhicules industriels conçus principalement pour une exploitation non routière, tels que les engins forestiers et de construction.
L'IEC 61851-21-1:2017, conjointement avec l’IEC 61851-21-2, annule et remplace l’IEC 61851 21:2001. Elle constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’IEC 61851 21:2001:
a) le présent document traite désormais uniquement des essais CEM, et non plus des autres essais électriques;
b) les configurations d’essai sont définies de manière plus précise;
c) l’Annexe A "Réseaux fictifs, réseaux fictifs asymétriques et intégration des bornes de charge dans la configuration d’essai" a été ajoutée.
