17、T CIRCUIT USING PWM (PULSE WIDTH MODULATION) AND A CONTROL PILOT WIRE 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 interna
18、tional 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
19、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 participat
20、e 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 inte
21、rnational 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 reaso
22、nable 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
23、 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 confor
24、mity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publicati
25、on. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or f
26、or costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct
27、application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare In
28、ternational Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical develop
29、ment or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC/TS 62763, w
30、hich is a technical specification, has been prepared by IEC technical committee 69: Electric road vehicles and electric industrial trucks. Edition 2 of IEC 61851-1, published in 2010 is presently undergoing revision. This Technical Specification will be valid until the publication of Edition 3 of IE
31、C 61851-1. In this document, the numbers in square brackets at the beginning of a sentence, help to identify requirements.

The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data relate
34、d to the specific publication. At this date, the publication will be transformed into an International Standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. PD IEC/TS 62763:2013Copyright British Standards I

36、electrical energy to electric vehicles, principally for the charging of the traction batteries of the vehicle. It concerns all charging systems that ensure the pilot function with a pilot wire circuit with PWM for mode 2, mode 3 and mode 4 charging as described in the IEC 61851 series. As indicated
37、in the foreword, Edition 2 of IEC 61851-1, published in 2010 is presently undergoing revision. This Technical Specification will be valid until the publication of Edition 3 of IEC 61851-1.

39、mechanism for the supply of electrical energy to electric vehicles, principally for the charging of the traction batteries of the vehicle. It concerns all charging systems that ensure the pilot function with a pilot wire circuit with PWM for mode 2, mode 3 and mode 4 charging as described in the IEC
40、 61851 series. This document describes the functions and sequencing of events for this circuit based on the recommended typical implementation circuit parameters. The parameters indicated also ensure the interoperability of control pilot wire systems designed according to SAE J1772. This document is
41、 not applicable to vehicles using pilot functions that are not based on a PWM signal and a pilot wire. NOTE 1 In the context of this document the words “EV supply equipment” designate any one of the following: the AC EV supply equipment in mode 3, the in cable control box in mode 2 and/or the DC EV
42、supply equipment in mode 4. NOTE 2 The control pilot wire is a supplementary conductor, in addition to the power lines linking the vehicle to EV supply equipment via the vehicle coupler. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document
43、and are indispensable for its application. For dated references, only the edition cited applies.

The EV (electric vehicle) supply equipment may cut off the power after at least 5 s in case the EV will use more current than the duty cycle indicates. It is recommended to de-energize the sy
48、stem, if the measured current exceeds the current signalled by duty cycle with a tolerance of 10 %. RA03-010 The circuit parameters shall be designed in accordance with Table 2, Table 3 and 3.4. RA03-020 The functionality of the pilot line shall follow the requirements defined in Table 2, Table 6, Table 7, and Table 8.
