标准范围

IEC 62680-1-2:2016（E）定义了涵盖USB系统所有元件的电源传输系统，包括:主机、设备、集线器、充电器和电缆组件。本规范描述了管理高达100W的USB供电所需的体系结构、协议、电源行为、连接器和布线。本规范旨在完全兼容并扩展现有的USB基础设施。本规范旨在允许系统原始设备制造商、电源和外围设备开发商在不丧失向后兼容性的情况下，为产品多功能性和市场差异化提供足够的灵活性。USB电源传输设计为独立于用于协商电源的现有USB总线定义机制运行。

IEC 62680-1-2:2016(E) defines a power delivery system covering all elements of a USB system including: Hosts, Devices, Hubs, Chargers and cable assemblies. This specification describes the architecture, protocols, power supply behaviour, connectors and cabling necessary for managing power delivery over USB at up to 100W. This specification is intended to be fully compatible and extend the existing USB infrastructure. It is intended that this specification will allow system OEMs, power supply and peripheral developers adequate flexibility for product versatility and market differentiation without losing backwards compatibility. USB Power Delivery is designed to operate independently of the existing USB bus defined mechanisms used to negotiate power.
