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;

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

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.
