标准范围

IEC 62680-1-2:20 17（E）定义了涵盖USB系统所有元件的电力输送系统，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100 W的USB供电所需的架构、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。本规范旨在为系统原始设备制造商、电源和外围设备开发商提供足够的灵活性，以实现产品多功能性和市场差异化，而不会失去向后兼容性。USB电力传输被设计为独立于用于协商电力的现有USB总线定义的机制运行，这些机制是:-[USB 2.0]、[USB 3.1]频带中对高功率接口的请求。-[USBBC 1.2]用于提供更高功率的机制(本规范未强制要求)。-[USB Type-C 1.2]用于提供更高功率的机制

IEC 62680-1-2:2017(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 behavior, connectors and cabling necessary for managing power delivery over USB at up to 100 W. 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 which are:
- [USB 2.0], [USB 3.1]in band requests for high power interfaces.
- [USBBC 1.2]mechanisms for supplying higher power (not mandated by this specification).
- [USB Type-C 1.2]mechanisms for supplying higher power
