Electric vehicle conductive charging system - Part 1: General requirements

IEC 61851-1:2010 applies to on-board and off-board equipment for charging electric road vehicles at standard a.c. supply voltages (as per IEC 60038) up to 1 000 V and at d.c. voltages up to 1 500 V, and for providing electrical power for any additional services on the vehicle if required when connected to the supply network. It includes characteristics and operating conditions of the supply device and the connection to the vehicle; operators and third party electrical safety, and the characteristics to be complied with by the vehicle with respect to the a.c./d.c. EVSE, only when the EV is earthed. This second edition cancels and replaces the first edition published in 2001. It constitutes a technical revision. The main changes with respect to the first edition of this standard are: - revision of connector definitions and current levels (Clause 8); - modification definition of pilot wire to pilot function; - division of Clause 9 to create Clauses 9 and 11; - Clause 9: specific requirements for inlet, plug and socket-outlet; - Clause 11: EVSE requirements: the basic generic requirements for charging stations; - renumbering of annexes; - deletion of previous Annex A and integration of charging cable requirements into new Clause 10; - Annex B becomes Annex A and is normative for all systems using a PWM pilot function with a pilot wire; Annex C becomes Annex B; - replacement of previous Annex D (coding tables for power indicator) with B.4 in Annex B using new values; - new informative Annex C describing an alternative pilot function system.

Système de charge conductive pour véhicules électriques - Partie 1: Règles générales

La CEI 61851-1:2010 est applicable aux systèmes embarqués ou non embarqués pour la charge des véhicules routiers électriques à des tensions alternatives normalisées (conformément à la CEI 60038) jusqu'à 1 000 V et à des tensions continues jusqu'à 1 500 V, ainsi que pour l'alimentation en énergie électrique pour tout service auxiliaire du véhicule pendant la connexion au réseau électrique, si nécessaire. Elle couvre les caractéristiques et les conditions de fonctionnement du système d'alimentation et le raccordement au véhicule, la sécurité électrique des opérateurs et des tiers, et les caractéristiques à respecter par le véhicule en ce qui concerne le courant alternatif (c.a) et le courant continu (c.c) uniquement lorsque le VE est mis à la terre. Cette deuxième édition annule et remplace la première édition, parue en 2001. Elle constitue une révision technique. Les principales modifications par rapport à la première édition de cette norme sont les suivantes: - la révision des définitions des connecteurs et des niveaux de courant (Article 8); - modification de la définition de fil pilote en fonction pilote; - division de l'Article 9 pour créer les Articles 9 et 11; - Article 9: Exigences spécifiques pour le socle de connecteur, la prise de courant; - Article 11: Dispositions du SAVE: Les exigences de base génériques pour les stations de charge; - renumérotation des annexes; - suppression de l'Annexe A précédente et introduction d'exigences techniques du câble de charge dans le nouvel Article 10; - l'Annexe B devient Annexe A et elle est normative pour tous les systèmes utilisant une fonction pilote de type PWM avec fil pilote; - l'Annexe C devient l'Annexe B; - remplacement de la précédente Annexe D (tableaux de codage pour l'indicateur de puissance) par le B.4 de l'Annexe B avec de nouvelles valeurs; - nouvelle Annexe C informative décrivant un autre système de fonction pilote.

Special national condition: National characteristic or practice that cannot be changed even over a long

period, e.g. climatic conditions, electrical earthing conditions.

NOTE If it affects harmonization, it forms part of the European Standard or Harmonization Document.

For the countries in which the relevant special national conditions apply these provisions are normative,

for other countries they are informative.

Part 1: General requirements
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in som
