                  美國能效六級與歐盟能效六級對比差異說明

                     美國能效六級與歐盟能效六級對比差異說明 歐盟CoC V5六級能效與美國DoE VI能源之星六級Energy Star VI能效雖然都是六級能效但是還是有很多的標準各自不同.下面我們來對比一下.

                   

                     首先我們來看看原文的美國DoE VI能源之星六級Energy Star VI能效相關要求和標準:


                  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 s 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 lel 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:

                     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).

                  The no-load power consumption and the energy efficiency shall be measured and declared
                  according to the method in the Annex.

                  Effective dates:
                  Tier 1: 1 January 2014
                  Tier 2: 1 January 2016

                     根據以上美國能源部和歐盟公布的能效測試要求,很明顯看出,美國的能效要求更嚴格,

                     下面用12V1.5A 電源適配器舉例說明:

                    1. 按照 DOE 要求: 12V1.5A 電源適配器,輸出功率為18W, 平均效率要求為: Average Efficiency = 0.071*In(18)-0.0014*18+0.67= 85.0016% No Load Input Power < 0.1W

                    2. 按照 CoC V5 的要求: 12V1.5A 電源適配器,輸出功率為18W, 平均效率要求為: Average Efficiency = 0.0626*In(18)+0.646= 82.693% No Load Input Power < 0.15 W

                     根據以上對比結果,美國能效要求相比較歐洲能效法規來講,要高出近2.4%.
