Universal serial bus interfaces for data and power - Part 1-1: Common components - USB Battery Charging Specification, Revision 1.2
用于数据和电源的通用串行总线接口 - 第1-1部分:常用组件 - USB电池充电规范 修订1.2
IEC 62680-1-1:2015(E) contains specifications that define limits as well as detection, control and reporting mechanisms to permit devices to draw current in excess of the USB 2.0 specification for charging and/or powering up from dedicated chargers, hosts, hubs and charging downstream ports. These mechanisms are backward compatible with USB 2.0 compliant hosts and peripherals.
