About Universal Charging Solution Project

A GSMA Project, supported by major GSM mobile network operators

and handset vendors, for example;

4

Project Objectives

Achieve environmental benefits by limiting the number of charger

models shipped and improving charger energy efficiency

Enhance customer experience by simplifying charging of a mobile

phone

Promote standards based and interoperable charging solutions

compatible for many mobile devices, worldwide

Enhance GSM industry reputation by communication of UCS

environmental benefits

Universal Charging Solution (UCS) explained

UCS contains three distinct parts as defined in OMTP CCLDC1

Common Power Supply

Common Detachable Cable

Charging and Local Data Connector

1 OMTP Common Charging and Local Data Connectivity 1.0

6

Common Power Supply

Present a USB Standard-A receptacle

Deliver a minimum of 850mA @ DC 5.0V 5%

Achieve a no-load consumption ≤0.15W

Meet or exceed EU directive 278/2009 energy efficiency targets

Comply with all USB-IF Battery Charging Specifications1

Standard-A receptacle

1 USB-IF Battery Charging Specification 1.1

7

Common Detachable Cable

USB Standard-A plug on Common Power Supply end

USB Micro-B plug on Terminal end

Meet all characteristics defined in USB Specification 2.02

2 USB-IF Universal Serial Bus Specification 2.0

8

USB Micro-B Plug - Detail

9

Charging and Local Data Connector

USB Micro-AB or USB Micro-B connector

Meet characteristics defined in USB-IF Micro-USB 1.013

Micro-ABReceptacle

Micro-BReceptacle

EITHER a Micro-A or Micro-B plug can be inserted.- If a Micro-A plug is inserted the device can

provide power to inserted accessory - If a Micro-B plug is inserted the device can

draw power/charge

Micro-B receptacle allows ONLY a Micro-B plug to be inserted. - The device can draw power/charge

Impact of Universal Charging Solution

Environmental Benefits

– up to a 50% reduction in standby energy consumption

– the potential elimination of up to 51,000 tonnes of duplicate chargers4

– UCS (CPS) must have a 4-star5 or higher no-load energy rating (which uses

up to three times less energy than an unrated charger) and must meet all

efficiency regulations6.

– With potentially 50% fewer chargers7 being manufactured each year, the

industry can expect to reduce greenhouse gases in manufacturing and

transporting replacement chargers by 1.44 million tonnes a year.

Consumer Benefits

– enhanced and simplify the end-user experience

– carry fewer chargers and charge from any available charger

– re-use chargers when changing handsets

– UCS provides for innovation in retail and consumer choice

4 GSMA analysis from UNEP, Gartner, European Commission Integrated Product Policy Pilot on Mobile Phones, University of Southern Queensland data. An estimated 1.2 billion mobile phones were sold in 2008, of which between 50-80 per cent were replacement handsets. That equals between 51,000 and 82,000 tonnes of replacement chargers every year. 5The Charger Energy Rating scheme is a voluntary initiative by several manufacturers to measure the amount of energy wasted when a charger is plugged in but not actively charging a connected device. 5 is the highest possible rating.6based on EU and US requirements. It is more stringent than the requirements of the European Commission Code of Conduct on Energy Efficiency of External Power Supplies (Version 3)6 or the US Environmental Protection Agency ENERGY STAR V7.7Assumes that 50 per cent of phones are replacement phones
