Interoperability specifications and communication method for external power supplies used with computing and consumer electronics devices (IEC 63002:2021)

This International Standard defines common charging interoperability guidelines for power sources (external power supplies (EPS) and other Sources) used with computing and consumer electronics devices that implement the IEC 62680-1-3: USB Type-C®1 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 (Figure 1) and certain safety elements of the EPS, cable, and device. While the requirements focus of this document is on the EPS (External Power Supply) and the behavior at its USB Type-C connector interface, it is also important to comprehend cable assembly and device capabilities and behaviors in order to assure end-to-end charging interoperability. The scope does not apply to all design aspects of an EPS. An EPS compliant with this standard is also expected to follow other applicable global standards and regulatory compliance requirements for aspects such as product safety, EMC and energy efficiency.
[Figure 1]
This International Standard provides recommendations for the behavior of a device when used with a power source compliant with this document. This International Standard specifies the minimum hardware specification for an EPS implementing IEC 62680-1-3: USB Type-C. This document also specifies the data objects used by a charging system utilizing IEC 62680-1-2: USB Power Delivery Specification to understand the identity, design and performance characteristics, and operating status of an external power supply. IEC 62680-1-2 and IEC 62680-1-3 focus on power delivery applications ranging to 100W for a variety of computing and consumer electronic devices including notebook computers, tablets, smartphones, small form-factor desktops, monitor displays and other related multimedia devices.
Future updates to IEC 62680-1-2 and IEC 62680-1-3 specifications will extend to enable power delivery applications that require more than 100W while remaining within the technical limitations of the USB Type-C cable and connector solution.
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 standard.

Interoperabilitäts-Spezifikationen und Kommunikationsverfahren für externe Stromversorgungen zur Anwendung für Computer- und Unterhaltungselektronikgeräte (IEC 63002:2021)

Spécifications d'interopérabilité et méthode de communication pour les alimentations externes utilisées avec les dispositifs informatiques et les dispositifs électroniques grand public (IEC 63002:2021)

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 facul

Specifikacije in komunikacijske metode medobratovalnosti zunanjih napajalnikov, ki se uporabljajo pri računalniških in potrošniških elektronskih napravah (IEC 63002:2021)

Ta mednarodni standard določa splošne smernice glede medobratovalnosti za polnjenje za vire napajanja (zunanje napajalnike (EPS) in druge vire napajanja), ki se uporabljajo pri računalniških in potrošniških elektronskih napravah v skladu s standardom IEC 62680-1-3: Specifikacija za kable in priključke univerzalnega serijskega vodila tipa C®.
Ta dokument določa normativne zahteve za zunanji napajalnik za namene zagotavljanja medobratovalnosti; določa zlasti podatke, posredovane iz vira napajanja v napravo (slika 1) ter določene varnostne elemente zunanjega napajalnika, kabla in naprave. Čeprav se zahteve v tem dokumentu osredotočajo na zunanji napajalnik in delovanje v njegovem vmesniku priključka USB tipa C, je pomembno razumeti tudi zmogljivosti ter delovanje kabelskih sklopov in naprav, da se zagotovi medobratovalnost za polnjenje od začetka do konca. Področje uporabe se ne uporablja za vse vidike zasnove zunanjega napajalnika. Pričakuje se, da zunanji napajalnik, skladen s tem standardom, izpolnjuje tudi določila ustreznih globalnih standardov in zahteve glede skladnosti s predpisi za vidike, kot so varnost izdelkov, elektromagnetna združljivost in energijska učinkovitost.
Ta mednarodni standard podaja priporočila za delovanje naprave, kadar se uporablja z virom napajanja, skladnim s tem dokumentom. Ta mednarodni standard določa minimalno specifikacijo strojne opreme za zunanji napajalnik v skladu s standardom IEC 62680-1-3: USB tipa C. Ta dokument določa tudi podatkovne objekte, ki jih uporablja sistem za polnjenje v skladu s standardom IEC 62680-1-2: Specifikacija za zagotavljanje napajanja prek USB za razumevanje identitete, zasnove in zmogljivosti ter stanja delovanja zunanjega napajalnika. Standarda IEC 62680-1-2 in IEC 62680-1-3 se osredotočata na zagotavljanje moči (do največ 100 W) različnim računalniškim in potrošniškim elektronskim napravam, vključno s prenosnimi računalniki, tabličnimi računalniki, pametnimi telefoni, namiznimi računalniki z malim ohišjem, monitorji za prikazovanje in drugimi povezanimi večpredstavnostnimi napravami.
Prihodnje posodobitve specifikacij IEC 62680-1-2 in IEC 62680-1-3 bodo razširjene, da bo omogočeno zagotavljanje moči napravam, ki zahtevajo več kot 100 W, obenem pa bodo ostale znotraj tehničnih omejitev rešitve za kable in priključke univerzalnega serijskega vodila tipa C.
Ta dokument temelji na uveljavljenih mehanskih in električnih specifikacijah ter komunikacijskih protokolih, ki jih določata standarda IEC 62680-1-2 in IEC 62680-1-3. Te specifikacije podpirajo metode za določitev najučinkovitejše medobratovalnosti med nepreizkušenimi kombinacijami zunanjih napajalnikov in naprav s ciljem povečati zadovoljstvo potrošnikov.
V podporo izvajanju tega standarda so podane tudi informacije, ki opisujejo model medobratovalnosti za polnjenje prek USB, pregled specifikacije priključka USB tipa C in specifikacije za zagotavljanje napajanja prek USB ter dejavnike za učinkovitost polnjenja.

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.

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 for 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 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.

This document has been prepared by technical area 18: Multimedia home systems and

applications for end-user networks, of IEC technical committee 100: Audio, video and

multimedia systems and equipment. It is an International Standard.

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.

94 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in

95 addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

96 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

97 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

98 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

99 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

100 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

101 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

102 consensus of opinion on the relevant subjects since each technical committee has representation from all

103 interested IEC National Committees.

104 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

105 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

106 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

107 misinterpretation by any end user.

108 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

109 transparently to the maximum extent possible in their national and regional publications. Any divergence between

110 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

111 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

112 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

113 services carried out by independent certification bodies.

114 6) All users should ensure that they have the latest edition of this publication.

115 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

116 members of its technical committees and IEC National Committees for any personal injury, property damage or

117 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses

118 arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

119 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

120 indispensable for the correct application of this publication.

121 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

122 rights. IEC shall not be held responsible for identifying any or all such patent rights.

123 International Standard IEC 63002 has been prepared by technical area 18: Interfaces and

124 methods of measurement for personal computing equipment, of IEC technical committee 100:

125 Audio, video and multimedia systems and equipment.

156 INTRODUCTION

157 The objective of this International Standard is to enable common charging interoperability of

158 external power supplies (EPS) used with the increasing variety of computing and consumer

159 electronic devices that implement the IEC 62680-1-3: USB Type-C® cable and connector and

160 the IEC 62680-1-2: USB Power Delivery standards. Broad market adoption of this

161 International Standard is expected to make a significant contribution to the global goals of

162 consumer convenience and re-usability of power supplies by expanding common charging

163 interoperability across different product categories while preserving backwards compatibility

170 interoperability enables manufacturers to design specific EPS that match the requirements of

171 target devices (functionality, cost, etc.) and use cases, while at the same time enabling

172 consumers to use the EPS for charging other IEC 62680 compliant devices, across various

173 product types.

174 IEC 62680-1-3 adoption is well underway in global markets for a wide range of devices using

175 as much as 100 Watts including notebook computers, tablets, smartphones, small form-factor

176 desktop computers and other consumer electronics. This International Standard enables the

177 reporting of the identity and power characteristics of power sources (external power supplies

178 (EPS) and other Sources) supported by IEC 62680-1-3 (USB Type-C) and specifies

179 interoperability guidelines when using IEC 62680-1-2 (USB Power Delivery). The method for

180 identification of a specific power source can enable equipment manufacturers to ensure

181 compliant operation using these specifications and promotes data communication that can be

182 used by the device to predict and mitigate interoperability concerns when an unfamiliar or

183 incompatible EPS is connected to the device. EPS power delivery applications can in the

184 future extend beyond 100 Watts given updates to IEC 62680 that appropriately address the

185 needs of higher-power products in the computing and consumer device market.

186 This International Standard also provides important information regarding consumer safety,

187 system reliability as well as relevant global standards and regulatory compliance.

188 Other international and regional standards, and government policies for “universal/common

189 power adapters” that reference this International Standard should take into account open

190 technical and regulatory compliance issues that are associated with untested or arbitrary

191 combinations of EPS and devices such as those identified in Annex A, as well as the

192 limitations and issues with approaches to define “common chargers” in meeting market needs.

193 For clarity, this International Standard focuses on interoperability specifications in order to

194 support global industry in developing safe, convenient, environmentally conscious, and end-to-

195 end interoperable charging solutions that meet regulatory compliance and market requirements.

201 This International Standard defines common charging interoperability guidelines for power

202 sources (external power supplies (EPS) and other Sources) used with computing and consumer

203 electronics devices that implement the IEC 62680-1-3: USB Type-C Cable and Connector

204 Specification.

205 This document defines normative requirements for an EPS to ensure interoperability, in

206 particular it specifies the data communicated from a power source to a device (Figure 1) and

207 certain safety elements of the EPS, cable, and device. While the requirements focus of this

208 document is on the EPS (External Power Supply) and the behavior at its USB Type-C connector

209 interface, it is also important to comprehend cable assembly and device capabilities and

210 behaviors in order to assure end-to-end charging interoperability. The scope does not apply

211 to all design aspects of an EPS. An EPS compliant with this standard is also expected to follow

212 other applicable global standards and regulatory compliance requirements for aspects such as

213 product safety, EMC and energy efficiency.
214
215 Figure 1 – Scope of the identification, communication and control method

216 This International Standard provides recommendations for the behavior of a device when used

217 with a power source compliant with this document. This International Standard specifies the

218 minimum hardware specification for an EPS implementing IEC 62680-1-3: USB Type-C. This

219 document also specifies the data objects used by a charging system utilizing IEC 62680-1-2:

220 USB Power Delivery Specification to understand the identity, design and performance

221 characteristics, and operating status of an external power supply. IEC 62680-1-2 and IEC 62680-

222 1-3 focus on power delivery applications ranging to 100W for a variety of computing and consumer

223 electronic devices including notebook computers, tablets, smartphones, small form-factor

224 desktops, monitor displays and other related multimedia devices.

225 Future updates to IEC 62680-1-2 and IEC 62680-1-3 specifications will extend to enable power

226 delivery applications that require more than 100W while remaining within the technical

227 limitations of the USB Type-C cable and connector solution.

228 This document relies on established mechanical and electrical specifications, and

229 communication protocols specified by IEC 62680-1-2 and IEC 62680-1-3. These specifications
