IEC 61851-21-2:2018

Electric vehicle conductive charging system - Part 21-2: Electric vehicle requirements for conductive connection to an AC/DC supply - EMC requirements for off board electric vehicle charging systems

IEC 61851-21-2:2018 defines the EMC requirements for any off-board components or equipment of such systems used to supply or charge electric vehicles with electric power by conductive power transfer (CPT), with a rated input voltage, according to IEC 60038:2009, up to 1 000 V AC or 1 500 V DC and an output voltage up to 1 000 V AC or 1 500 V DC.
This document covers off-board charging equipment for mode 1, mode 2, mode 3 and mode 4 charging as defined in IEC 61851-1:2017.
This first edition, together with IEC 61851-21-1, 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 related tests instead of other electrical tests;
b) Clauses 2 and 3 have been updated;
c) the port definition, the test-setups and their corresponding limits as well as the operation modes are defined more precisely;
d) Annexes A to F have been added.

Système de charge par conduction pour véhicules électriques – Partie 21-2: Exigences applicables aux véhicules électriques pour connexion par conduction à une alimentation en courant alternatif ou courant continu – Exigences CEM concernant les systèmes de charge non embarqués pour véhicules électriques

IEC 61851-21-2:2018 définit les exigences CEM concernant les composants ou les équipements des systèmes de charge non embarqués qui permettent d'alimenter ou de charger les véhicules électriques par une source d'alimentation électrique par transfert d'énergie par conduction (CPT ), avec une tension d'entrée assignée, jusqu'à 1 000 V en courant alternatif ou jusqu'à 1 500 V en courant continu, conformément à l'IEC 60038:2009, et une tension de sortie jusqu'à 1 000 V en courant alternatif ou jusqu'à 1 500 V en courant continu.
Le présent document traite des équipements de charge non embarqués pour les charges en mode 1, mode 2, mode 3 et mode 4 telles que définies dans l’IEC 61851-1:2017.
Les câbles sans composants électroniques ou qui ne subissent aucune coupure électrique/électronique sont considérés comme passifs (faibles). Ils sont jugés par ailleurs conformes aux exigences d'émission et d'immunité du présent document sans qu'aucun essai ne s'avère nécessaire.
Le présent document ne s'applique à aucun composant embarqué, équipement de charge ou système d'alimentation faisant partie des véhicules. Les exigences CEM concernant ce type d’équipements sont couvertes par l'IEC 61851-21-1:2017.
La conformité aux exigences d'émission et d'immunité du présent document est vérifiée lorsqu'il peut être démontré que l’équipement en essai (EUT ) satisfait aux limites respectives, lors des essais de type effectués avec le dispositif de mesure du présent document.
Les exigences concernant les systèmes de transfert d'énergie sans fil (WPT) pour véhicules électriques sont couvertes dans l’IEC 61980 (toutes les parties).
IEC 61851-21-2:2018, avec l’IEC 61851-21-1, annule et remplace l’IEC 61851-21:2001. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC 61851-21:2001:
a) le présent document ne traite que des essais de CEM plutôt que d’autres essais électriques;
b) les Articles 2 et 3 ont été mis à jour;
c) les accès, les montages d’essai et leurs limites respectives ainsi que les modes de fonctionnement sont définis de façon plus précise;
d) les Annexes A à F ont été ajoutées.
