DOE和COC能效详解

首先我们来看看美国DoE VI能源之星六级Energy Star VI能效相关要求和标准:

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).
