计算和消费电子设备用外部电源的互操作性规范和通信方法（TA 18

[中文适用范围]： 本文件定义了用于实施 IEC 62680-1-3（USB Type-C 电缆和连接器规范）的计算和消费电子设备的电源（外部电源供应器 (EPS) 和其他电源）的通用充电互操作性指南。本文件定义了确保互操作性的 EPS 的规范性要求；特别是，它规定了从电源到设备传输的数据（图 1）以及 EPS、电缆和设备的一些安全要素。虽然本文件的要求重点在于 EPS 及其 USB Type-C 连接器接口处的行为，但为了确保持端到端的充电互操作性，还必须了解电缆组件和设备的能力和行为。本文件不适用于 EPS 的所有设计方面。本文件不规定产品安全、电磁兼容 (EMC) 或能源效率等方面的监管合规要求。 [外文原描述]： 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.
