ITU-T L.1000 (06/2011) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The
6、ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standard
7、ization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information te
8、chnology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compl
9、iance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other ob
10、ligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.

20、he requirements of a universal charger solution for mobile terminals and other hand-held ICT devices. Further study is required to extend the solution to other ICT devices. This Recommendation also takes into consideration energy efficiency, emissions reduction and the use of scarce and raw material
21、s. It has been estimated (see Appendix VIII) that the widespread adoption of a universal charger solution for mobile phones will result in a 50 per cent reduction in standby energy consumption and approximately 14 million tons of greenhouse gas emissions each year. The universal power adapter and ch
22、arger solution will be more convenient and simpler to use for consumers who will be able to charge their mobile phones from any available universal mobile charger and use the same power adapter for many future handsets, thus eliminating up to 50000 tons of duplicate power adapters and chargers. It i
23、s noted that the environmental impact of any universal charger solution should be considered over the entire life cycle and that the transition towards a universal charger solution does not aim to replace existing chargers immediately; this is because there is an estimated 2 billion of them currentl
24、y in use. This Recommendation was drafted with support from and in consideration of activity in other SDOs and other types of organizations. This Recommendation is designed to ensure the universal charger solution operates within recognized current and voltage safety parameters by adopting existing
25、mobile terminal technologies such as computer USB output or recharging solutions in cars. Battery safety and lifetime issues have been considered in the drafting of this Recommendation. Rec.

36、fined in this Recommendation This Recommendation defines the following terms: 3.1.1 charger: A common term used to describe the power adapter for the mobile terminal or other hand-held ICT devices used to apply power to the battery. 3.1.2 detachable cable: A detachable cable connects the power adapt
37、er to the mobile terminal or other hand-held ICT device for powering through two connectors, one on the charger side and one on the side of the mobile terminal or other hand-held ICT device. 3.1.3 power adapter: The equipment that converts mains AC power voltage at the input to low DC power voltage

40、s USB Universal Serial Bus 5 Basic configuration of universal power adapter and charger solution The target basic configuration of a universal charger solution consists of: 1) a power adapter (charger of the mobile terminal), other ICT device for charging (which can also be used for data transfer),
41、or a renewable energy power supply (e.g., solar, wind); 2) a detachable cable (used for charging or data transfer) or optionally a captive cable (used for charging only), depending on market demand; 3) a mobile terminal or other hand-held ICT device. NOTE Further study is needed to specify more deta
42、ils (e.g., logical, functional or physical). Rec. ITU-T L.1000 (06/2011) 3 6 General requirements 6.1 Power adapter interface The power adapter is required to provide an output DC voltage and DC current. NOTE A dedicated specification for mobile terminals is shown in Annex B. 6.2 Energy efficiency r
43、equirements 6.2.1 No-load power consumption The no-load power consumption of the power adapter should be as low as practicable. It is expected that the industry will aim for a figure as close to zero as possible. If practicable, the power adapter should indicate to the customer its no load condition
44、. It is expected that industry will aim for power adapters and chargers to enter a shut-down mode to minimize power consumption either when the unit is removed from the supply or when the battery is fully charged, thereby ensuring significant energy savings. NOTE A dedicated specification for mobile
45、 terminals is shown in Annex B. 6.2.2 Power efficiency with load It is expected that industry will aim to minimize the power dissipated in the power adapter whilst powering the load device. An example of an evaluation of battery charging efficiency is given in Annex B. NOTE A dedicated specification
46、 for mobile terminals is shown in Annex B. 6.2.3 Solar power for chargers and mobile phones and related ICT devices Solar-powered mobile terminals could provide mobile connectivity to about two billion people across the globe that do not have access to electricity. Solar power has the advantage of b
47、eing more sustainable and better for the environment than the electricity grid which currently uses fossil fuel in its mix of energy sources. It is therefore recommended that power adapters and chargers, mobile terminals and other ICT devices be designed to make maximum use of available renewable en
48、ergy sources. NOTE 1 This can be of considerable interest for the requirements of some developing countries, e.g., solar, wind power. As an example, power adapter and charger interfaces would need to be designed so that they do not stress the batteries inside the mobile terminal or other ICT device
49、by providing too much current when solar input is also taking place. High temperature stresses on the ICT device caused by sun exposure should also be avoided. NOTE 2 In the future, this Recommendation may be updated to use additional renewable energy sources such as wind or other forms of energy harvesting as a source of power. 6.3 Safety requirements The power adapter must be a limited power source in accordance with clause 2.5 of IEC 60950-1, and comply with the safety requirements of IEC
