IEC 63002:2021
(Main)Interoperability specifications and communication method for external power supplies used with computing and consumer electronics devices
Interoperability specifications and communication method for external power supplies used with computing and consumer electronics devices
IEC 63002:2021 defines common charging interoperability guidelines for power sources (external power supplies (EPSs) and other Sources) used with computing and consumer electronics devices that implement IEC 62680-1-3 (USB Type-C Cable and Connector Specification).
This document defines normative requirements for an EPS to ensure interoperability; in particular, it specifies the data communicated from a power source to a device and certain safety elements of the EPS, cable, and device. While the requirements focus of this document is on the EPS and the behaviour at its USB Type-C connector interface, it is also important to comprehend cable assembly and device capabilities and behaviours in order to assure end-to-end charging interoperability. This document does not apply to all design aspects of an EPS. This document does not specify regulatory compliance requirements for aspects such as product safety, EMC or energy efficiency.
This document provides recommendations for the behaviour of a device when used with a power source compliant with this document. It specifies the minimum hardware specification for an EPS implementing IEC 62680-1-3. This document also specifies the data objects used by a charging system utilizing IEC 62680-1-2 to understand the identity, design and performance characteristics, and operating status of an external power supply. IEC 62680-1-2 focuses on power delivery applications ranging to 100 W for a variety of computing and consumer electronics devices including notebook computers, tablets, smartphones, small form-factor desktops, monitor displays and other related multimedia devices.
This document relies on established mechanical and electrical specifications, and communication protocols specified by IEC 62680-1-2 and IEC 62680-1-3. These specifications support methods for establishing the best performing interoperability between untested combinations of EPS and devices with the aim of improving consumer satisfaction.
Information describing the USB charging interoperability model, overview of USB Type-C and USB Power Delivery specifications, and factors for charging performance are also provided to support implementation of this document.
IEC 63002:2021 cancels and replaces the first edition published in 2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) title is changed from Identification and communication interoperability method for external power supplies used with portable computing devices;
b) Clause 4, EPS interoperability based on USB technologies, is added;
c) Clause 5, EPS specification, adds hardware and protection requirements; overvoltage protection is changed from optional to normative;
d) Annex B and Annex C are added, providing an explanation of the design features in USB Power Delivery that enhance reliability and an explanation of the concepts of charge rate and power.
Spécifications d'interopérabilité et méthode de communication pour les alimentations externes utilisées avec les dispositifs informatiques et les dispositifs électroniques grand public
L'IEC 63002:2021 définit des lignes directrices pour l'interopérabilité de la charge commune des sources d'alimentation (alimentations externes [EPS] et autres Sources) utilisées avec les dispositifs informatiques et les dispositifs électroniques grand public qui mettent en œuvre l'IEC 62680-1-3 (spécification des câbles et connecteurs USB Type-C).
Le présent document définit les exigences normatives des EPS en matière d'interopérabilité; il spécifie notamment les données communiquées par une source d'alimentation à un dispositif (voir Figure 1) et certains éléments de sécurité de l'EPS, du câble et du dispositif. Alors que les exigences définies dans le présent document concernent l'EPS et le comportement au niveau de l'interface de son connecteur USB Type-C, il est également important de comprendre les capacités et le comportement des ensembles de câbles et des dispositifs afin d'assurer une interopérabilité de bout en bout de la charge. Le présent document ne couvre pas tous les aspects de conception d'une EPS. Le présent document ne définit pas les exigences de conformité réglementaire pour des aspects tels que la sécurité des produits, la comptabilité électromagnétique (CEM) ou l'efficacité énergétique.
Le présent document fournit des recommandations pour le comportement d'un dispositif lorsqu'il est utilisé avec une source d'alimentation conforme au présent document. Il spécifie les caractéristiques matérielles minimales exigées pour une EPS qui met en œuvre l'IEC 62680-1-3. Le présent document spécifie également les objets de données utilisés par un système de charge conforme à l'IEC 62680-1-2 pour comprendre les caractéristiques d'identité, de conception et de performance, ainsi que l'état de fonctionnement d'une alimentation externe. L'IEC 62680-1-2 se concentre sur les applications d'alimentation jusqu'à 100 W pour une large gamme de dispositifs informatiques et de dispositifs électroniques grand public, notamment les ordinateurs portables, les tablettes, les mobiles multifonctions, les ordinateurs de bureau compacts, les moniteurs et d'autres dispositifs multimédias analogues.
Le présent document s'appuie sur les spécifications mécaniques et électriques établies, ainsi que sur les protocoles de communication spécifiés dans l'IEC 62680-1-2 et l'IEC 62680-1-3. Ces spécifications décrivent les méthodes qui visent à optimiser l'interopérabilité entre les combinaisons EPS-dispositif qui n'ont pas été soumises à l'essai dans le but d'améliorer la satisfaction du client.
Le présent document décrit également le modèle d'interopérabilité de la charge USB, la spécification USB Type-C et la spécification de l'alimentation électrique par port USB, ainsi que les facteurs de rendement de charge nécessaires aux fins de mise en œuvre.
L'IEC 63002:2021 annule et remplace la première édition parue en 2016. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) la présente norme a été renommée (anciennement intitulée Méthode d'identification et d'interopérabilité des communications des alimentations externes utilisées avec les dispositifs informatiques portatifs);
b) le nouvel Article 4 traite de l'Interopérabilité de l'EPS avec les technologies USB;
c) l'Article 5, Spécification EPS, fournit des exigences relatives au matériel et à la protection; la protection à maximum de tension n'est plus facultative, mais est désormais normative;
d) les nouvelles Annexe B et Annexe C décrivent les caractéristiques de conception de l'alimentation électrique par port USB qui améliorent la fiabilité; elles expliquent également les concepts de régime et de puissance de charge.

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 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 publication.
