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.

INTRODUCTION
The objective of this document is to enable common charging interoperability of external power
supplies (EPSs) used with the increasing variety of computing and consumer electronics
1
devices that implement IEC 62680-1-3 (USB Type-C® Cable and Connector Specification)
and IEC 62680-1-2 (USB Power Delivery). Broad market adoption of this document is expected
to make a significant contribution to the global goals of consumer convenience and re-usability
of power supplies by expanding common charging interoperability across different product
categories while preserving backwards compatibility with the installed base of billions of
IEC 62680 compliant devices worldwide.
This document specifies the minimum technical requirements for interoperability and includes
recommendations for EPS functionality when used with computing and electronics devices. The
approach taken by this document, focused on enabling common charging interoperability, can
allow manufacturers to innovate in aspects such as technical design, system performance, and
energy efficiency. Furthermore, common charging interoperability enables manufacturers to
design specific EPSs that match the requirements of target devices (functionality, cost, etc.)
and use cases, while at the same time enabling consumers to use the EPS for charging other
IEC 62680 compliant devices, across various product types.
IEC 62680-1-3 adoption is well underway in global markets for a wide range of devices using
as much as 100 W, including notebook computers, tablets, smartphones, small form-factor
desktop computers, and other consumer electronics devices. This document enables the
reporting of the identity and power characteristics of power sources (EPSs and other Sources)
supported by IEC 62680-1-3 (USB Type-C) and specifies interoperability guidelines when using
IEC 62680-1-2 (USB Power Delivery). The method for identification of a specific power source
can enable equipment manufacturers to ensure compliant operation using these specifications
and promotes data communication that can be used by the device to predict and mitigate
interoperability concerns when an unfamiliar or incompatible EPS is connected to the device.
EPS power delivery applications can in the future extend beyond 100 W given updates to
IEC 62680 that appropriately address the needs of higher-power products in the computing and
consumer device market.
This document also provides important information regarding consumer safety, system
reliability as well as relevant global standards and regulatory compliance.
Other international and regional standards, and government policies for "universal" or "common
power adapters" that reference this document are expected to take into account open technical
and regulatory compliance issues that are associated with untested or arbitrary combinations
of EPSs and devices such as those identified in Annex A, as well as the limitations and issues
with approaches to define "common chargers" in meeting market needs. For clarity, this
document focuses on interoperability specifications in order to support global industry in
developing safe, convenient, environmentally conscious, and end-to-end interoperable charging
solutions that meet regulatory compliance and market requirements.
