美国能效六级与欧盟能效六级对照差别申明 欧盟CoC V5六级能效与美国DoE VI动力之星六级Energy Star VI能效固然都是六级能效可是仍是有良多的规范各自差别.上面咱们来对照一下.
起首俺们分析看译文的美利坚共和国DoE VI的动力新星六级Energy Star VI能耗等级相干post请求和规范化:
External Power Supplies
External power supplies (EPS) convert household electric current into direct current or lower-voltage alternating current to operate a consumer product such as a laptop computer or smart phone. There are hundreds of product types that use an EPS and over 300 million EPSs are shipped each year. Energy conservation standards have been in place for external power supplies since 2007.
The standards implemented in 2007 will save approximately 3.8 quads of energy and result in approximately $42.4 billion in energy bill savings for products shipped from 2008-2032. The standard will avoid about 198.5 million metric tons of carbon dioxide emissions, equivalent to the annual greenhouse gas emissions of about 39 million automobiles.
The standards implemented in 2014 will save consumers up to an additional $3.8 billion and cut emissions by nearly another 47 million metric tons of carbon dioxide over 30 years, equivalent to the annual electricity use of 6.5 million homes.
Standards for External Power Supplies
The following content summarizes the energy conservation standards for external power supplies. The text is not an official reproduction of the Code of Federal Regulations and should not be used for legal research or citation.
Current Standard
Direct Operation EPS Standards
The new efficiency standards for EPSs established efficiency standards for Direct Operation External Power Supplies. All direct operation external power supplies manufactured on or after two years after the final rule’s date of publication in the Federal Register shall meet the following standards:

AIM
To minimise energy consumption of external power supplies both under no-load and load conditions in the output power range 0.3W to 250W.
COMMITMENT
Signatories of this Code of Conduct commit themselves to:
Design power supplies or component so as to minimise energy consumption of external power supplies. Those companies who are not responsible for the production of power supplies shall include the concept of minimisation of energy consumption in their purchasing procedures of power supplies.
Achieve both the no-load power consumption and on-mode efficiency targets shown in Table 1.1, Table 2.1 and 2.2 for at least 90% of products2, for the new models of external power supplies that are introduced on the market or specified in a tender/procurement after the effective date (for new participants after the date they have signed the Code of conduct).

是以这美式的和动力部和欧洲经济共同体上架的功效测评提起，很较着知道，美式的的功效提起更严酷，
上面用12V1.5A 蘑菇视频
适配器举例申明：
1. 按照 DOE 请求： 12V1.5A 蘑菇视频
适配器，输入功率为18W, 均匀效力请求为： Average Efficiency = 0.071*In(18)-0.0014*18+0.67= 85.0016% No Load Input Power < 0.1W
2. 按照 CoC V5 的请求： 12V1.5A 蘑菇视频
适配器，输入功率为18W, 均匀效力请求为： Average Efficiency = 0.0626*In(18)+0.646= 82.693% No Load Input Power < 0.15W
是以以下对比重大成果，荷兰功效重定向对比较美国功效律例言之，要高于跨越式近2.4%.
