Forward

ICT help economy and society reduce carbon

ICT can also reduce carbon from itself



Reduce carbon from ICTs



Reduce e-waste from ICTs

• ICT device needs AC / DC power convertor

Normally every ICT device has at lease one power charge, power adapter or power switch unit

• At the end of life, ICT devices and its power units are kinds of e-waste



Universal power charger for mobile phones and ICTs

ITU-T Study Group 5

ITU-T Recommendation L.1000 Universal power adapter and charger solution for mobile terminals and other ICT devices (March 2010)



ITU-T Recommendation L.1000 Summary

• Provides high level requirements for a universal power adapter and charger solution that will reduce the number of power adapters and chargers produced and recycled by widening their application to more devices and increasing their lifetime.

• Also aims to reduce energy consumption. The longer life cycle and possibility of avoiding device duplication reduces the demand on raw materials and waste.

• Designed to serve the great majority of mobile terminals and other ICT devices.



ITU-T L.1000 Scope

• This Recommendation describes the general requirements for a universal power adapter and charger solution for mobile terminals (e.g. mobile phones) and other ICT devices.

• This Recommendation includes basic configurations and general requirements for the power adapter and charger interface, energy efficiency, safety, electromagnetic compatibility, resistibility, and eco-environmental specifications.



L.1000 Basic configuration

One possible basic configuration of three elements for universal power adapter and charger solution



L.1000 Basic configuration

Basic elements of universal charger solution for mobile terminals



L.1000 Phase 2 study

• On April 2010, phase 2 study of L.1000 started at the ITU-T Study Group 5 meeting

• Study extends from mobile phones to more ICTs

xDSL, WLAN, Intelligent terminal, IP Phone, Media box, Netbook, Portable box, PC accessories, printer, scanner, battery charger…...



National/Regional Standardization



Future

More new powering technology may happen in the future: intelligent power supply, low voltage powering network, solar power, wind power, automatic powering……
