Reference EN 61851-1:2011
Title Electric vehicle conductive charging system - Part 1: General requirements
Project Number 22334
Abstract/Scope 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.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
