标准范围

IEC 63002:2021定义了与实现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一起使用的电源（外部电源（EPSs）和其他电源）的通用充电互操作性指南。本文件定义了EPS的规范性要求，以确保互操作性；特别地，它规定了从电源传送到设备的数据以及EPS、电缆和设备的某些安全元件。虽然本文档的要求重点是EPS及其USB Type-C连接器接口的行为，但理解电缆组件和设备功能和行为也很重要，以确保端到端充电互操作性。本文件不适用于EPS的所有设计方面。本文件未规定产品安全、EMC或能效等方面的法规遵从性要求。本文件提供了与符合本文件的电源一起使用时设备行为的建议。它规定了实现IEC 62680-1-3的EPS的最低硬件规格。本文件还规定了利用IEC 62680-1-2的充电系统用于了解外部电源的标识、设计和性能特征以及操作状态的数据对象。IEC 62680-1-2专注于各种计算和消费电子设备（包括笔记本电脑、平板电脑、智能手机、小型台式机、监视器显示器和其他相关多媒体设备）高达100 W的功率输送应用。本文件依赖于IEC 62680-1-2和IEC 62680-1-3规定的既定机械和电气规范以及通信协议。这些规范支持在未经测试的EPS和设备组合之间建立最佳性能互操作性的方法，目的是提高消费者满意度。还提供了描述USB充电互操作性模型、USB Type-C和USB电源传输规范概述以及充电性能因素的信息，以支持本文档的实施。IEC 63002:2021取消并取代了2016年发布的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)标题从与便携式计算设备一起使用的外部电源的识别和通信互操作性方法改变；b)增加条款4，基于USB技术的EPS互操作性；c)EPS规范第5条增加了硬件和保护要求；过压保护由选配改为规范；d)增加了附录B和附录C，解释了USB电源传输中增强可靠性的设计特征，并解释了充电速率和功率的概念。

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.
