The Energy Policy and Conservation

Act (EPCA) of 1975 established an

energy conservation program for

major household appliances. Section

135(c)(4) of the Energy Policy Act of

2005 amended section 325 of EPCA

(42 U.S.C. 6295) by adding subsection

Register for Email Updates

The Department is firmly committed to

informing the public of developments

associated with this rulemaking.

Register to receive email updates on

rulemaking for battery chargers and

external power supplies.

(u) for battery chargers and external

power supplies. Battery chargers are

devices that charge batteries for consumer products, including chargers

embedded in consumer products. External power supplies are devices that

convert household electric current into DC current or lower-voltage AC current

in order to operate consumer products.

Subsection (u) of EPCA directs the Secretary to specify definitions and test

procedures for measuring the energy consumption of battery chargers and

external power supplies, after providing notice and an opportunity for

comment. In establishing these test procedures, the Secretary is directed to

consider existing definitions and test procedures that measure energy

consumption in standby mode and other modes.

In addition, subsection (u) of EPCA directs the Secretary to issue a

determination, by August 8, 2008, whether energy conservation standards

shall be developed for battery chargers and external power supplies. In the

determination, the Department will assess the current and projected market

for battery chargers and external power supplies. This assessment will include

estimates of potential energy savings from technical improvements to battery

chargers and external power supplies and will suggest product classes for

energy conservation standards.

Finally, subsection (u) of EPCA requires that the Department hold a scoping

workshop to discuss and receive comments on plans for developing energy

conservation standards for battery chargers and external power supplies.

As this rulemaking process continues, DOE will post documents here and notify

stakeholders of these updates through its email distribution list. Please register

to receive notification of any updates through the gray box above.

The test procedure for battery chargers and external power supplies is part of

a rulemaking process establishing test procedures for several products

contained in the Energy Policy Act of 2005. To facilitate review of the certain

portions of this Final Rule, the Department highlighted the terms 'battery

charger' and 'external power supply' throughout the Final Rule.

Determination Analysis

The Energy Policy Act of 2005 (EPACT) directs DOE to determine whether

energy conservation standards are warranted for battery chargers and

external power supplies. As part of that process, EPACT requires that DOE hold

a scoping workshop not later than February 8, 2007, to discuss and receive

comments on plans for developing energy conservation standards for energy

use of battery chargers and external power supplies.

DOE has scheduled a scoping workshop to discuss plans for developing energy

conservation standards for battery chargers and external power supplies. In

addition, DOE has prepared two documents that constitute supporting material

for this scoping workshop. The first is called "Plans for Developing Energy

Conservation Standards for Battery Chargers and External Power Supplies."

This document describes the procedural and analytical approach DOE

anticipates using to evaluate whether energy conservation standards are

warranted for battery chargers and external power supplies, and to develop

such standards should DOE make a positive determination. The second is

called "The Current and Projected Future Market for Battery Chargers and

External Power Supplies." This document presents an initial market and

technology assessment for battery chargers and external power supplies. It

also discusses potential product classes and criteria DOE is considering in

establishing product classes.
