Interoperability specifications of common external power supply (EPS) for use with data-enabled mobile telephones
IEC 62684:2018 is also available as IEC 62684:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62684:2018 specifies the interoperability of common external power supplies for use with data-enabled mobile telephones. It defines the common charging capability and specifies interface requirements for the external power supply. Safety and EMC aspects are not covered by this document. Safety is covered by IEC 60950-1 or IEC 62368-1 and EMC is covered by regional /national standards. This document defines interoperability based on legacy USB technologies and does not cover charging interfaces that implement IEC 62680-1-3, IEC 62680-1-2 and IEC 63002. This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Clause 1 is modified to include updated references to IEC Universal Serial Bus interface standards;
b) Clause 2 is expanded to include references to IEC Universal Serial Bus interface standards;
c) Subclause 4.1 is expanded to include requirements for non USB Micro-B plug DC plug connectors;
d) Subclause 4.4 is modified to remove obsolete requirements for common mode noise and reference requirements of IEC Universal Serial Bus interface standards;
e) Subclause 4.5 is modified to reference appropriate safety standards.
Spécifications d'interopérabilité des alimentations externes (eps) communes destinées aux téléphones mobiles avec service de données
L'IEC 62684:2018 spécifie l'interopérabilité des alimentations externes communes destinées aux téléphones mobiles avec service de données. Il définit la fonctionnalité de charge commune et spécifie les exigences d'interface relatives à l'alimentation externe.
Les aspects relatifs à la sécurité et à la compatibilité électromagnétique (CEM) ne sont pas couverts par le présent document. La sécurité est couverte par l'IEC 60950-1 ou l'IEC 62368-1. La CEM est couverte par des normes régionales/nationales.
Le présent document définit l'interopérabilité avec les technologies USB antérieures et ne couvre pas les interfaces de charge qui mettent en œuvre l'IEC 62680-1-3 (câbles et connecteurs USB Type-C™), l'IEC 62680-1-2 (alimentation électrique par port USB) et l'IEC 63002.
L'IEC 62684:2018 annule et remplace la première édition parue en 2011. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) l'Article 1 a été modifié afin de mettre à jour les références vers les normes de l'IEC relatives aux interfaces de bus série universel;
b) l'Article 2 a été enrichi afin d'inclure les références vers les normes de l'IEC relatives aux interfaces de bus série universel;
c) le 4.1 a été enrichi afin d'inclure les exigences relatives aux connecteurs mâles pour courant continu non USB Micro-B;
d) le 4.4 a été modifié afin de supprimer les exigences obsolètes en matière de bruit en mode commun et de référencer les exigences des normes de l'IEC relatives aux interfaces de bus série universel;
e) le 4.5 a été modifié afin de référencer les normes de sécurité applicables.
