EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62680-3 testing. The Battery Charge Working Group is empowered to create specifications that define limits as well as detection, control and reporting mechanisms to allow devices to draw current above the USB 2.0 specification for charging or powering from dedicated chargers, mainframes, hubs. Charging downstream ports. These mechanisms are backward compatible with USB 2.0 compliant hosts and peripherals.
USB ports on personal computers are convenient places for Portable Devices (PDs) to draw current to charge their batteries. This convenience has led to the creation of USB Chargers, which simply spawned a USB standard-A outlet. This allows PDs to use the same USB cable to charge from a PC or a USB Charger.
For a PD to determine how much current it is allowed to draw from an upstream USB port, there must be mechanisms that allow the PD to distinguish between a Standard Downstream Port and a Charging Port. This specification defines just such mechanisms.
Because PDs can be plugged into USB chargers from various manufacturers, it's important that they all provide an acceptable user experience. This specification defines the requirements for a compatible USB charger, referred to in this specification as a USB Charger.
The Low Battery Threshold is defined as the minimum charge level of a battery, above which a device is guaranteed to be able to power on successfully.
A Low Battery is defined as a battery that is above the Dead Battery Threshold and below the Low Battery Threshold. A device with a weak Battery may or may not be able to successfully power on a device.
