BS EN 62680-3:2013

This standard BS EN 62680-3:2013 Universal serial bus interfaces for data and power is classified in these ICS categories:

• 29.200 Rectifiers. Converters. Stabilized power supply
• 33.120.20 Wires and symmetrical cables
• 29.220.01 Galvanic cells and batteries in general
• 35.200 Interface and interconnection equipment

The Battery Charging Working Group is chartered with creating 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.
