RIN 1904-AD45
Energy Conservation Program: Test Procedures for Battery Chargers
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: The U.S. Department of Energy (DOE) is proposing to revise its
test procedure for battery chargers established under the Energy Policy
and Conservation Act of 1975, as amended (EPCA). These proposed
revisions, if adopted, would harmonize the instrumentation resolution
and uncertainty requirements with the second edition of the
International Electrotechnical Commission (IEC) 62301 standard and
other international standards for measuring standby power.
Additionally, the proposed amendments would update and propose new
battery selection criteria for multi-voltage, multi-capacity battery
chargers, and
[[Page 46856]]
provide specific steps on how to select a battery for those chargers
when more than one battery meets the selection criteria, such as with a
multi-chemistry battery charger. The proposal also outlines new
provisions for conditioning and discharging lead acid batteries.

I. Authority and Background
Title III of the Energy Policy and Conservation Act of 1975 (42
U.S.C. 6291 et seq.; ``EPCA'' or, ``the Act'') sets forth a variety of
provisions designed to improve energy efficiency. (All references to
EPCA refer to the statute as amended through the Energy Efficiency
Improvement Act of 2015, Public Law 114-11 (April 30, 2015). Part B of
Title III, which for editorial reasons was re-designated as Part A upon
incorporation into the U.S. Code (42 U.S.C. 6291-6309, as codified),
establishes the ``Energy Conservation Program for Consumer Products
Other Than Automobiles.'' Battery chargers are among the products
affected by these provisions.
Under EPCA, the energy conservation program consists essentially of
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation
standards, and (4) certification and enforcement procedures. The
testing requirements consist of test procedures that manufacturers of
covered products must use as the basis for (1) certifying to DOE that
their products comply with the applicable energy conservation standards
adopted under EPCA, and (2) making representations about the efficiency
of those products. Similarly, DOE must use these test procedures to
determine whether the products comply with any relevant standards
promulgated under EPCA.
[[Page 46857]]
General Test Procedure Rulemaking Process
Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures
DOE follows when prescribing or amending test procedures for covered
products. EPCA provides in relevant part that any test procedures
prescribed or amended under this section shall be reasonably designed
to produce test results that measure the energy efficiency, energy use,
or estimated annual operating cost of a covered product during a
representative average use cycle or period of use and shall not be
unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))
In addition, when DOE determines that a test procedure requires
amending, it publishes a notice with the proposed changes and offers
the public an opportunity to comment on the proposal. (42 U.S.C.
6293(b)(2)) As part of this process, DOE determines the extent to
which, if any, the proposed test procedure would alter the measured
energy efficiency of any covered product as determined under the
existing test procedure. (42 U.S.C. 6293(e)(1))
Section 135 of the Energy Policy Act of 2005 (``EPACT 2005''),
Public Law 109-58 (Aug. 8, 2005), amended sections 321 and 325 of EPCA
by adding certain provisions related to battery chargers. Among these
provisions were new definitions defining what constitutes a battery
charger and a requirement that DOE prescribe ``definitions and test
procedures for the power use of battery chargers and external power
supplies.'' (42 U.S.C. 6295(u)(1)(A)) DOE complied with this
requirement by publishing a test procedure final rule on December 8,
2006, that established a new Appendix Y to address the testing of
battery chargers to measure their energy consumption and adopted
several definitions related to the testing of battery chargers. See 71
FR 71340 (codified at 10 CFR part 430, subpart B, appendix Y ``Uniform
Test Method for Measuring the Energy Consumption of Battery
Chargers''). Lastly, DOE incorporated by reference specific sections of
the EPA's ``Test Methodology for Determining the Energy Performance of
Battery Charging Systems'' when measuring inactive mode energy
consumption.
Section 310 of the Energy Independence and Security Act of 2007
(``EISA 2007''), Public Law 110-140 (Dec. 19, 2007) then amended
section 325 of EPCA by defining active mode, standby mode, and off
mode. (42 U.S.C. 6295(gg)(1)(A)) This section also directed DOE to
amend its existing test procedures by December 31, 2008, to measure the
energy consumed in standby mode and off mode for battery chargers. (42
U.S.C. 6295(gg)(2)(B)(i)) Further, it authorized DOE to amend, by rule,
any of the definitions for active, standby, and off modes (42 U.S.C.
6295(gg)(1)(B)) Accordingly, the Department issued a notice of proposed
rulemaking (NOPR) in 2008, 73 FR 48054 (Aug. 15, 2008), and a final
rule in early 2009 to establish definitions for these terms. (74 FR
13318, March 27, 2009)
Subsequently, in response to numerous testing issues raised by
commenters in the context of DOE's energy conservation standards
rulemaking efforts for battery chargers,\1\ DOE issued another NOPR on
April 2, 2010 (75 FR 16958). The NOPR proposed adding a new active mode
energy consumption test procedure for battery chargers that would
assist in developing potential energy conservation standards for these
products. DOE also proposed amending portions of its standby and off
mode battery charger test procedure to shorten the overall measurement
time. DOE held a public meeting to discuss its test procedure NOPR on
May 7, 2010, where it also received comments on the proposals set forth
in the NOPR.

---------------------------------------------------------------------------
After receiving comments at the public meeting, DOE published a
final rule that codified a new active-mode test procedure and amended
the standby and off-mode test procedures then-present in appendix Y to
subpart B of part 430 in the CFR. 76 FR 31750 (June 1, 2011). That rule
became effective 30 days after publication in the Federal Register, but
manufacturers were allotted 180 days from the rule's publication to use
the new test procedure when making written representations of the
energy efficiency of their chargers. As federal standards for battery
chargers have yet to be finalized, DOE has not required manufacturers
to submit energy efficiency data for their products tested under the
battery charger test procedure.
Following the publication of the most recent final rule, DOE
continued to receive additional questions and requests for
clarification regarding the testing, rating, and classification of
battery chargers. As part of the continuing effort to establish federal
efficiency standards for battery chargers and to develop a clear and
widely applicable test procedure, DOE published a Notice of Data
Availability (NODA) on May 15, 2014 (79 FR 27774). This NODA sought
comment from stakeholders concerning the repeatability of the test
procedure when testing battery chargers with several consumer
configurations, and on the anticipated market penetration of new
battery charging technologies that may require further revisions to
DOE's regulations. DOE also sought comment on the reporting
methodologies for manufacturers attempting to comply with the
California Energy Commission's (CEC's) efficiency standards for battery
chargers in order to understand certain data discrepancies in the CEC
database. DOE indicated its interest in soliciting feedback to
determine whether the current procedure contained any ambiguities
requiring clarification. These issues were discussed during DOE's NODA
public meeting on June 3, 2014.
To ensure the test procedure's clarity, DOE's proposal, which is
based on commenter feedback to the NODA, would make certain
clarifications to appendix Y to subpart B of 10 CFR part 430 and
include a sampling plan for battery chargers in 10 CFR part 429. These
proposed changes would include updated references to the latest version
of IEC 62301 and clarify DOE's test methods for specific types of
battery chargers to better reflect evolving technologies.
II. Summary of the Notice of Proposed Rulemaking
This proposal seeks to make several changes to the current test
procedure for measuring the energy use of battery chargers.
First, DOE is proposing to amend the existing battery selection
criteria to limit the number of batteries selected for testing to a
single battery. DOE is proposing that only the battery with the highest
rated voltage and/or highest rated charge capacity, from those among
which the battery charger is capable of charging, would be tested for
each basic model. Additionally, DOE is proposing that if at least two
distinct batteries meet the criteria of having the highest rated
voltage and highest rated charge capacity, the battery charger and
battery combination with the highest maintenance mode power would be
selected for testing. (``Maintenance mode'' is defined as ``the mode of
operation when the battery charger is connected to the main electricity
supply
[[Page 46858]]
and the battery is fully charged, but is still connected to the
charger.'' See 10 CFR part 430, subpart B, appendix Y, Sec. 2.8.)
Second, the proposed changes would exclude back-up battery chargers
embedded in continuous use devices from being required to be tested
under the DOE procedure. This proposed exclusion would harmonize with
DOE's approach currently under consideration regarding the potential
regulation of battery back-up systems (including uninterruptible power
supplies (UPSs)) as part of the Computer and Back-up Battery Systems
rulemaking.
Third, the proposed changes would harmonize DOE's test procedure
with the latest version of IEC 62301 by providing specific resolution
and measurement tolerances. These specifications would assist in
ensuring that testing is performed with equipment that is capable of
reaching these tolerances and that the resulting measurements are
repeatable and reproducible.
Fourth, DOE is proposing to change how lead acid batteries are
conditioned and discharged by applying the protocol currently used for
all other battery chemistries (excluding lithium-ion) to lead acid
batteries. DOE has become aware that a lead acid battery's condition
may vary upon purchase and this variation can impact lead acid battery
performance. In an effort to minimize these effects, DOE is proposing
to require that the batteries be conditioned prior to testing.
Additionally, DOE has been informed that discharge rate can
significantly impact the nominal battery energy of lead acid batteries,
especially in the case of flooded lead acid batteries. Stakeholders
have claimed that the discharge rate as determined by the current DOE
test procedure is higher than that during typical use, and therefore
does not give an accurate representation of the battery energy in lead
acid batteries. (NMMA, No. 12, p. 4) Accordingly, DOE is proposing to
lengthen the discharge time for lead acid batteries to mitigate these
effects.
Fifth, DOE is proposing to add product-specific certification
reporting requirements into 10 CFR 429.39(b), which is currently
reserved. DOE is also proposing to add a sampling methodology to be
used for determining representations of efficiency, energy and power
consumption, and other key battery charger characteristics. These
proposals would specify the required data elements to certify
compliance with any energy conservation standards for battery chargers
that DOE may adopt, and also would provide a method for DOE to enforce
compliance with any energy conservation standards for battery chargers
that DOE may promulgate.
Sixth, DOE is proposing to correct an internal cross-reference in
the current version of Table 3.1 contained in 10 CFR part 430, subpart
B, appendix Y and to add units to the measured and calculated values in
the table. The updates would also remove the empty value column
currently found in Table 3.1. DOE is also proposing to specify in
section 430.23(aa) that battery discharge energy should be measured
according to section 3.8 of appendix Y.
The table below summarizes the changes and the affected sections of
10 CFR parts 429 and 430.

----------------------------------------------------------------------------------------------------------------
A. Battery Selection and Testing of Multi-Voltage, Multi-Capacity
Battery Chargers
DOE sought comments on the existing battery selection methodology
included in section 4.3 ``Selection of Batteries To Use for Testing''
of the test procedure in its recent NODA as it relates to multi-
voltage, multi-voltage and multi-capacity, and multi-chemistry battery
chargers. See 79 FR 27774, 27776-27777 (May 15, 2014).The submitted
comments suggested that errors may be introduced when testing these
types of battery chargers and raised questions about the repeatability
of the test procedure when testing battery chargers capable of charging
batteries of different chemistries (i.e., chargers capable of handling
multiple battery chemistries such as lithium and nickel metal hydride).
PTI urged DOE to state explicitly how each battery charger and battery
combination should be rated. (PTI, Pub. Mtg. Transcript, No. 6 at p.
77) ITI commented that the current test procedure leaves significant
room for error and does not employ effective, reasonable and repeatable
test conditions for these types of battery chargers. (ITI, No. 19, pp.
2-3) The CA IOUs and NRDC both offered solutions to eliminate ambiguity
in battery selection for these battery chargers by suggesting that the
least expensive battery or the battery which represents the most common
intended use be selected. (California IOUs, No. 15, p. 2, NRDC, No. 20,
p. 2) DOE took all of these comments into account when developing its
proposal.
Under the current provisions for battery selection, a multi-
voltage, multi-capacity battery charger must be tested with as many as
three distinct battery types. The battery selection procedure under
Appendix Y, Section 4, Table 4.1, lays out three sets of testing
scenarios:
(a) Test unit with the lowest voltage, lowest capacity battery
utilizing only one port.
(b) Test unit with the highest voltage, lowest capacity battery
utilizing only one port.
(c) Use all ports and use the battery or configuration of batteries
with the highest total rated energy capacity.
Per section 4.3.a(2), if no batteries are packaged with the
charger, but the instructions specify or recommend batteries for use
with the charger, batteries for testing must be those recommended or
specified in the instructions and must be selected according to the
procedure in section 4.3.b, which generally requires that a tester use
Table 4.1 to determine which batteries to use when testing the
efficiency of a given battery charger. In the case of multi-chemistry
battery chargers, multiple batteries of differing chemistries may meet
the criteria outlined in 4.3.b for a single battery selection and test.
Specifically, the current test procedure is not clear which battery
chemistry, or chemistries, should be selected for testing--it indicates
only that the battery with the highest voltage or highest rated charge
capacity be selected. In this case, the test results for each battery
of differing chemistries may be inconsistent even though they have the
same voltage and charge capacity. Finally, DOE realizes that the
current battery selection criteria can result in the selection of up to
three separate batteries for testing, which increases testing burden
and may create ambiguity as to which test result to use when making a
representation about the energy efficiency of a battery charger.
[[Page 46860]]
DOE is proposing an approach that would reduce ambiguity and testing
burden, while yielding repeatable measurements of a tested unit's
energy use.
Specifically, to eliminate potential ambiguity and reduce testing
burden, DOE is proposing to modify Table 4.1 to eliminate the multiple
tests currently required for multi-voltage and multi-capacity battery
chargers and instead require that only the battery with the highest
voltage and/or highest charge capacity be selected. In doing so, DOE's
goal is to test the charger in the mode for which the battery charger
is designed to operate optimally. Based on feedback from industry
representatives and consultation with subject matter experts, DOE
understands that, if required to operate over a range of outputs, power
electronics, including battery chargers, are typically designed to
optimize components at the high output range of the device. Therefore,
DOE believes these test results will be representative of the typical
energy consumption of the battery charger and reduce the possibility of
placing undue burden on manufacturers of chargers that are able to
charge lower voltage, lower capacity batteries.
To address these same issues, DOE is also proposing that if a
battery charger is multi-voltage and multi-capacity and capable of
charging batteries of multiple chemistries (such that two or more
batteries, each with a unique chemistry, meet the proposed selection
criteria) the battery and battery charger combination resulting in the
highest maintenance mode power would be chosen for testing.
DOE anticipates that, with these proposed changes, there will be
only one set of test results, and a single rating, for each basic model
of battery charger. The resulting energy consumption calculation would
be repeatable and representative of each basic model's energy use for
which it has been optimized, while eliminating the ambiguity that
appears to be present in the current version of the procedure.
Additionally, by reducing the number of tests required, DOE believes
that the overall test burden would be reduced. DOE seeks comment on the
proposed methodology for selecting batteries for multi-voltage, multi-
capacity battery chargers, and for those cases when the battery
selection criteria results in two or more unique batteries (e.g.,
multi-chemistry battery chargers).
DOE notes that it also considered several other options to modify
the test procedure to clarify how to measure the energy use of, and
obtain a single set of energy consumption ratings for, multi-voltage
and multi-capacity battery chargers. First, DOE considered requiring
the existing battery selection criteria to be applied and then
averaging the test results to produce one set of test results. Second,
DOE considered modifying the battery selection criteria to require that
only the battery with the lowest voltage and/or lowest rated charge
capacity be selected for testing. Lastly, in the case of multi-
chemistry battery chargers, DOE considered requiring the battery
charger be considered a basic model for each base chemistry it was
capable of charging and apply the battery selection criteria separately
for each chemistry, or basic model.
Each one of these proposed solutions, however, resulted in
solutions that did not fully accomplish DOE's goals. The first option,
while producing a single set of test results, could result in an
unrepresentative measurement of the true energy consumption consistent
with any configuration of batteries the battery charger is capable of
charging. The second option, while similar to DOE's proposal, would not
produce results representative of the higher range for which battery
chargers are, typically, optimally designed when capable of charging
multiple voltages and capacities. Finally, in addressing battery
chemistry, treating each chemistry mode as a unique basic model, with
either of the previous options discussed above, did not produce a
single metric and could increase the testing burden on some
manufacturers. In DOE's view, this approach would produce test results
that are repeatable and representative of the typical energy
consumption of the battery charger under test and at the same time
reduce testing burden on manufacturers. While DOE's preliminary
determination is that these options conflict with those intentions, DOE
is seeking comment on these other options as well.
B. Back-Up Battery Chargers
DOE sought comments on applying the current test procedure to
battery chargers embedded in continuous use products, or back-up
battery chargers, in the recent NODA. See 79 FR 27774. Based on
comments received from interested parties and DOE's own analysis, DOE
is proposing to define back-up battery chargers and exclude them from
the scope of this test procedure. DOE is proposing to define back-up
battery chargers in 10 CFR 430.2 as a battery charger that: (1) Is
embedded in a separate end-use product that is designed to continuously
operate using main power (AC or DC) and (2) has as its sole purpose to
recharge a battery used to maintain continuity of load power in case of
input power failure. DOE previously referred to these battery chargers
in the context of continuous use devices in the May 2014 NODA. Examples
of such devices that integrate back-up battery chargers include UPSs
and some cable modems. Interested parties noted to DOE that continuous
use devices are becoming increasingly integrated with a variety of
products that do not perform back-up battery charging as a primary
function of the device. As a result of this integrated approach, the
battery charging function in these products often cannot be isolated
during testing (ARRIS, No. 22, p. 2). While the test procedure is
designed to measure the energy consumption and efficiency of the
battery charging functionality, the method is limited when applied to a
battery charger that is embedded among other functions that cannot be
isolated during testing. Citing this reason, ARRIS suggested that these
types of devices be excluded from the scope of the test procedure.
(ARRIS, No. 22, p. 2).
ARRIS also noted that, in the event that DOE does not exclude these
types of back-up battery chargers embedded in continuous use devices
from the scope of this procedure, DOE should add provisions
specifically to address the testing of these units. ARRIS suggested
amending the test procedure to provide for measurement of only the
battery charging functionality of continuous use devices that lack an
on/off switch and for which the battery cannot be removed. The
suggested alternative includes measuring 24-hour energy consumption
(``E24'') with a fully charged battery, then again measuring E24 with a
discharged battery. ARRIS's approach would use the absolute difference
between these two values to represent the 24-hour energy consumption of
the unit under test (UUT). (ARRIS, No. 12, p. 4-6)
Additionally, the CA IOUs and NRDC both suggested that if DOE plans
to require back-up battery chargers embedded in continuous use devices
to be tested under the current test procedure, manufacturers should add
an on-off switch to turn off all additional functionality. (CA IOUs,
No. 15, p. 3, NRDC, No. 20, p. 3) ARRIS argued, however, that adding
switches to disable non-charging functionality in a device where
multiple functions, including battery charging, have been integrated at
the system or chipset level--which helps achieve lower manufacturing
costs and increased reliability and energy efficiency--is not feasible.
(ARRIS, No. 22, p. 3).
[[Page 46861]]
Based on its own testing data and the feedback received from
commenters, at this time, DOE is proposing to exclude back-up battery
chargers that are embedded in continuous devices from the testing
requirements of the DOE battery charger test procedure. DOE may revisit
this decision in the future as circumstances permit.
Consistent with this proposed approach, DOE is also proposing to
define the term ``back-up battery charger'' in Sec. 430.2 and add to
Section 1 of Appendix Y language specifying that back-up battery
chargers would be excluded from the scope of the test procedure. DOE
recognizes that its previously proposed standards for battery chargers
considered products that would now be excluded from the scope of the
test procedure. If back-up battery chargers were removed from the scope
of test procedure, DOE would no longer consider establishing
conservation standards for these types of products as part of a
standards rulemaking for battery chargers. However, DOE is considering
energy conservation standards for some battery back-up systems
(including UPSs) as part of the Computer and Back-up Battery Systems
rulemaking. DOE seeks comments on this approach.
C. Measurement Accuracy and Precision
On June 13, 2005, the IEC published its first edition of testing
standard IEC 62301, which provided a method for measuring standby power
of household appliances. The standard quantified minimum resolution
requirements for energy measurement instruments and outlined the
necessary procedures to ensure stable energy readings for any UUT. The
standard also set limits on the uncertainties associated with any
measurement taken that is meant to represent the energy consumption of
a household device. It has since become recognized by many regulatory
bodies as the default guideline for any power or energy measurement
required for formal certification. DOE subsequently adopted
instrumentation resolution and measurement uncertainty requirements for
testing battery chargers identical to those in the IEC 62301 standard
and codified these requirements at 10 CFR part 430, subpart B, appendix
Y on June 1, 2011. 76 FR 31750.
The IEC published Edition 2.0 of IEC 62301 in January 2011. This
revised version of the testing standard refined the test equipment
specifications, measuring techniques, and uncertainty determination to
improve the method for measuring loads with high crest factors and/or
low power factors, such as the low power modes typical of battery
chargers operating in standby mode. These provisions were contained in
Section 4 of IEC 62301, with informative guidance provided in Annex B
and Annex D on measuring low power modes and determining measurement
uncertainty.
To continue to ensure test methods are harmonized, DOE is proposing
to incorporate by reference the resolution parameters for power
measurements and uncertainty methodologies found in Section 4 of the
second edition of the IEC 62301 standard. DOE seeks comment on the
merits of incorporating these revisions into the current battery
chargers test procedure in Appendix Y. DOE also seeks comment regarding
whether the use of Annex B and Annex D should be mandatory to ensure
the most accurate test results.
D. Conditioning and Discharge Rate for Lead Acid Battery Chargers
DOE received several comments from stakeholders suggesting changes
to both the conditioning of lead acid batteries and the discharge rate
for lead acid batteries. In some cases, DOE's own research also points
to a potential need to modify the current procedure to better account
for the specific characteristics of lead acid batteries. Currently, no
conditioning is performed for lead acid batteries. See 10 CFR part 430,
appendix Y, sec. 5.3.a.
First, Johnson Outdoor Marine Electronics (JOME) provided test
results with its comments indicating that the discharge energy of lead
acid batteries varies over several cycles. These results are contrary
to certain lead acid battery manufacturers' claims that conditioning is
not required. JOME stated that typical lead acid batteries are only at
75 to 80 percent capacity when they are delivered in new condition, and
JOME's test results show that lead acid battery discharge energy could
increase after just two cycles, the current value for all other battery
chemistries. (JOME, No. 9, p. 4-5) These data suggest that applying the
conditioning protocol outlined in the current appendix Y, section 5.3.c
(for batteries of other chemistries) as a prerequisite, prior to
testing lead acid batteries, will produce a more accurate
representation of battery discharge energy.
Providing the option of various discharge rates during battery
conditioning would also allow manufacturers to increase conditioning if
needed. JOME's data suggest that additional conditioning may be needed
to maximize discharge energy--in some cases up to 4 cycles or more.
Furthermore, JOME added that its conversations with battery
manufacturers indicate that a 50%-80% depth of discharge would produce
more accurate and representative results for lead acid batteries.
(JOME, No. 9, p. 4) To account for these issues, DOE is proposing to
apply the same battery conditioning provisions found in appendix Y,
Section 5.3.c, to lead acid batteries and use a 50% depth of discharge
during conditioning. DOE is seeking comment on applying the
conditioning protocol (two charges and two discharges, followed by a
charge, as a minimum) outlined in section 5.3.c of the test procedure
to lead acid batteries. DOE also seeks comment on amending the depth of
discharge requirement, during conditioning only, to 50% of the rated
voltage of the battery and what alternative depth of discharge
requirements (if any) should apply to lead acid batteries.
Second, JOME, the National Marine Manufacturers Association (NMMA),
and DOE's own research, indicate that the amount of usable energy
extracted from a lead acid battery is inversely proportional to its
discharge rate.\2\ (NMMA, No. 12, p. 3) Thus, a lead acid battery
discharged over a span of 10 hours produces a higher amount of overall
measured energy than one discharged over a period of 5 hours. To
address this issue, NMMA suggested that DOE allow for a longer
discharge cycle than the current 5 hours required in the battery
charger test procedure. (NMMA, No. 12, p. 4) Given that a longer
discharge rate may be more representative for certain lead acid
batteries, particularly those used in marine applications, DOE is
proposing to amend its procedure by providing manufacturers with the
option to choose between a 5-hour (C/5 or .2C), 10-hour (C/10 OR .1C),
or 20-hour (C/20 OR .05C) discharge rate when testing with batteries
that are rated above 1,000 watt-hours (Wh). DOE is limiting this option
to those batteries that are above 1,000 Wh because a longer discharge
cycle would do little to maximize discharge energy for batteries under
1,000 Wh, but would have a more significant impact on maximizing
discharge energy for batteries greater than 1,000 Wh. DOE seeks comment
on its proposed approach for lead acid batteries and whether the
approach as described above would require any adjustments. Should
adjustments be needed, DOE seeks feedback on what those adjustments
should be.

[[Page 46862]]
E. Sampling and Certification Requirements
DOE is proposing to update 10 CFR 429.39, section (a),
``Determination of represented value,'' and reserved section (b),
``Certification Reports,'' to detail how to apply the sampling plan to
calculate a represented value for each measure of energy consumption,
time, and power recorded as part of the battery charger test procedure,
and subsequently report those ratings during certification. For each
basic model, these ratings would be determined by applying the
statistical requirements outlined in 10 CFR 429.39 to a sample of
battery charger units that are tested according to the test procedure
in appendix Y. Specifically, a represented value would be calculated in
watts (W) for the measured maintenance mode power, the measured standby
mode power, and the measured off mode power; the Wh rating would be
calculated for the measured battery discharge energy and the measured
24-hour energy consumption. Additionally, the proposal would require
the certification report for each basic model of battery charger to
include each of the aforementioned represented values, along with the
manufacturer and model of the test battery used; the nameplate battery
voltage of the test battery in volts (V); the nameplate charge capacity
of the test battery in ampere-hours (Ah); the nameplate charge energy,
if available, of the battery in watt hours (Wh); the brand and model,
when applicable, of the external power supply (EPS) used for testing;
\3\ and the average duration of the charge and maintenance mode test in
hours (hr).
---------------------------------------------------------------------------
\3\ The test procedure states in section 4.1.a that ``[t]he
battery charger system shall be prepared and set up in accordance
with the manufacturer's instructions.'' See 10 CFR 430 appendix Y to
subpart B. Battery charger systems that include an EPS should be
tested with the EPS that is sold with the battery charger system in
accordance with the manufacturer's instructions. For battery
chargers that use an EPS but are not sold with an EPS, the system
should be tested according to the manufacturer's instructions on how
to supply power to the battery charger. Providing the manufacturer
and model for the EPS in the certification report would help ensure
test result repeatability in cases where the EPS necessary to supply
power to the charger is not included.
---------------------------------------------------------------------------
In 2012, DOE proposed to regulate battery charger energy use with a
single metric--Unit Energy Consumption (UEC)--derived from a
calculation of the amount of energy consumed by the battery charger
over the course of year. 77 FR 18478 (March 27, 2012). The inputs into
this calculation would include the represented values that DOE is
proposing to include as part of the certification requirements, along
with constants used to represent the estimated number of charges per
day and the number of hours each day that the battery charger spends in
each mode of operation. These usage profile assumptions were originally
proposed as part of the March 2012 NOPR. Therefore, should DOE finalize
energy conservation standards using the same UEC approach proposed in
the NOPR, the represented values included on the certification report
would allow DOE to calculate the UEC of each certified basic model of
battery charger and ensure compliance with energy conservation
standards.
DOE seeks comment on its proposal to update the sampling
requirements and reporting requirements for battery chargers to include
the data required to identify the battery charger and battery, as well
as measured ratings recorded in the test procedure. DOE is particularly
interested in whether the inclusion of these proposed categories of
information would present a significant burden on manufacturers to
produce as part of a submitted certification report--and if so, why.
F. Enforcement Testing Sampling Plan
To ensure that manufacturers of consumer products comply with the
applicable energy conservation standards, DOE conducts enforcement
testing by randomly selecting a sample of units and testing them
according to the test procedure. DOE then compares the results obtained
through this enforcement testing to the applicable energy conservation
standard to determine whether the basic model meets that standard. DOE
is proposing a sampling and calculation method for DOE to assess the
compliance of battery charger basic models.
When conducting enforcement testing for battery chargers, DOE is
proposing to test a sample of at least 4 units of a battery charger
basic model according to the provisions of the test procedure. DOE
would then determine the sample mean for each of the output metrics of
the test procedure, and then use those sample means to calculate the
basic model's UEC according to the UEC equation that would be set forth
as part of an energy conservation standard for battery chargers. DOE
would then determine compliance by comparing the UEC calculated as part
of enforcement testing to the applicable energy conservation standard.
DOE is proposing to add Appendix D to Subpart C of Part 429 of the CFR
to describe the methodology that DOE would use when conducting
enforcement testing of battery chargers. DOE seeks comments on this
proposal.
G. Other Proposed Updates
DOE is also proposing to update Table 3.1 of Appendix Y to correct
a cross-reference error and eliminate a redundant column. The Active
and Maintenance Mode Energy Consumption item on the fourth line in this
table currently references section 5.8, when it should reference
section 5.6, ``Testing Charge Mode and Battery Maintenance Mode.''
Additionally, DOE is proposing to remove the current ``Value'' column
because the information from that column can be inserted in the column
labeled ``Name of measured or calculated value'' column to reduce the
table's complexity. DOE seeks comment on these proposed simplification
changes.
H. Effective Date and Compliance Date of Test Procedure
If adopted, the effective date for the battery charger test
procedure would be 30 days after publication of the test procedure
final rule in the Federal Register. At that time, any measure of energy
consumption relying on these metrics may be represented pursuant to the
final rule. Consistent with 42 U.S.C. 6293(c), representations of the
energy consumption or energy efficiency of battery chargers must be
based on the new test procedure and sampling plans as of 180 days after
the date of publication of the test procedure final rule. Starting on
that date, any such representations, including those made on marketing
materials, Web sites (including qualification with a voluntary or State
program), and product labels would be required to be based on results
generated using the proposed procedure as well as the sampling plan in
10 CFR part 429.
I. Impact From the Test Procedure
When proposing to amend a test procedure, DOE typically determines
the extent to which, if any, the proposed test procedure would alter
the measured energy efficiency of any covered product when compared to
the existing test procedure. (42 U.S.C. 6293(e)(1)). Because DOE does
not currently have energy conservation standards for battery chargers,
this proposal would not affect this provision.
J. Wireless Power
In a March 2012 standards NOPR for battery chargers and EPSs, DOE
noted that there are a number of different products under the broad
umbrella of ``wireless power,'' including both battery chargers and
EPSs. See 77 FR 18478 (March 27, 2012) (notice of proposed rulemaking
to set standards for battery chargers and external power
[[Page 46863]]
supplies). In the May 2014 battery charger NODA, DOE sought input on
wireless charging stations that are specifically designed to operate in
dry environments, although DOE did not explicitly consider these
products when first developing the battery charger test procedure. (79
FR at 27776-27777) DOE plans to address this issue in a separate
rulemaking.
IV. Procedural Issues and Regulatory Review
A. Review Under Executive Order 12866
The Office of Management and Budget (OMB) has determined that test
procedure rulemakings do not constitute ``significant regulatory
actions'' under section 3(f) of Executive Order 12866, Regulatory
Planning and Review, 58 FR 51735 (October 4, 1993). Accordingly, this
action was not subject to review under the Executive Order by the
Office of Information and Regulatory Affairs (OIRA) in the Office of
Management and Budget.
B. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of an initial regulatory flexibility analysis (IFRA) for
any rule that by law must be proposed for public comment, unless the
agency certifies that the rule, if promulgated, will not have a
significant economic impact on a substantial number of small entities.
As required by Executive Order 13272, ``Proper Consideration of Small
Entities in Agency Rulemaking,'' 67 FR 53461 (August 16, 2002), DOE
published procedures and policies on February 19, 2003, to ensure that
the potential impacts of its rules on small entities are properly
considered during the DOE rulemaking process. 68 FR 7990. DOE has made
its procedures and policies available on the Office of the General
Counsel's Web site: http://energy.gov/gc/office-general-counsel.
For manufacturers of battery chargers, the Small Business
Administration (SBA) has set a size threshold, which defines those
entities classified as ``small businesses'' for the purposes of the
statute. DOE used the SBA's small business size standards to determine
whether any small entities would be subject to the requirements of the
rule. 65 FR 30836, 30848 (May 15, 2000), as amended at 65 FR 53533,
53544 (September 5, 2000) and codified at 13 CFR part 121. The size
standards are listed by North American Industry Classification System
(NAICS) code and industry description and are available at http://www.sba.gov/content/summary-size-standards-industry. Battery charger
manufacturers are classified under NAICS 335999, ``All Other
Miscellaneous Electrical Equipment and Component Manufacturing.'' The
SBA sets a threshold of 500 employees or less for an entity to be
considered as a small business for this category.
As discussed in the March 2012 NOPR, DOE identified one battery
charger original device manufacturer with domestic manufacturing. Based
on manufacturer interviews and DOE's research, DOE believes that almost
all battery charger manufacturing takes place abroad. Also, in the NOPR
and at the NOPR public meeting DOE asked for comment regarding the
impacts on small battery charger manufacturers and it received no
comments. Therefore, based on the information DOE currently has at
hand, DOE certifies that this proposed rule is unlikely to have a
significant impact on a substantial number of small entities.
DOE reviewed this proposed rule under the provisions of the
Regulatory Flexibility Act and the procedures and policies published on
February 19, 2003. This proposed rule prescribes certain limited
clarifying amendments to an already-existing test procedure that will
help manufacturers and testing laboratories to consistently conduct
that procedure when measuring the energy efficiency of a battery
charger, including in those instances where compliance with the
applicable Federal energy conservation standard is being assessed. DOE
has tentatively concluded that the proposed rule would not have a
significant impact on a substantial number of small entities.
Accordingly, DOE has not prepared a regulatory flexibility analysis for
this rulemaking. DOE will transmit the certification and supporting
statement of factual basis to the Chief Counsel for Advocacy of the SBA
for review under 5 U.S.C. 605(b).
C. Review Under the Paperwork Reduction Act of 1995
If DOE adopts energy conservation standards for battery chargers,
manufacturers of battery chargers will be required to certify that
their products comply with those standards. In certifying compliance,
manufacturers must test their products according to the applicable DOE
test procedure, including any amendments adopted for those test
procedures. DOE has established regulations for the certification and
recordkeeping requirements for all covered consumer products and
commercial equipment and is proposing specific requirements for battery
chargers in this rule. See 10 CFR part 429, subpart B. The collection-
of-information requirement for the certification and recordkeeping is
subject to review and approval by OMB under the Paperwork Reduction Act
(PRA). This requirement has been approved by OMB under OMB control
number 1910-1400. This information collection was renewed in January
2015 to include certification requirements for battery chargers. 80 FR
5099 (January 30, 2015). Public reporting burden for the certification
is estimated to average 30 hours per response, including the time for
reviewing instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information.
Notwithstanding any other provision of the law, no person is
required to respond to, nor shall any person be subject to a penalty
for failure to comply with, a collection of information subject to the
requirements of the PRA, unless that collection of information displays
a currently valid OMB Control Number.
D. Review Under the National Environmental Policy Act of 1969
The proposed test procedure amendments will likely be used to
develop and implement future energy conservation standards for battery
chargers. DOE has determined that this rule falls into a class of
actions that are categorically excluded from review under the National
Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE's
implementing regulations at 10 CFR part 1021. Specifically, this
proposed rule would amend the existing test procedures without
affecting the amount, quality or distribution of energy usage, and,
therefore, would not result in any environmental impacts. Thus, this
rulemaking is covered by Categorical Exclusion A5 under 10 CFR part
1021, subpart D, which applies to any rulemaking that interprets or
amends an existing rule without changing the environmental effect of
that rule. Accordingly, neither an environmental assessment nor an
environmental impact statement is required.
E. Review Under Executive Order 13132
Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4, 1999)
imposes certain requirements on agencies formulating and implementing
policies or regulations that preempt State law or that have Federalism
implications. The Executive Order requires agencies to examine the
constitutional and statutory authority supporting any action that would
limit the policymaking discretion of the States and to carefully assess
the necessity for such actions. The
[[Page 46864]]
Executive Order also requires agencies to have an accountable process
to ensure meaningful and timely input by State and local officials in
the development of regulatory policies that have Federalism
implications. On March 14, 2000, DOE published a statement of policy
describing the intergovernmental consultation process it will follow in
the development of such regulations. 65 FR 13735. DOE has examined this
proposed rule and has determined that it would not have a substantial
direct effect on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government. EPCA governs
and prescribes Federal preemption of State regulations as to energy
conservation for the products that are the subject of this proposed
rule. States can petition DOE for exemption from such preemption to the
extent, and based on criteria, set forth in EPCA. (42 U.S.C. 6297(d))
No further action is required by Executive Order 13132.
F. Review Under Executive Order 12988
Regarding the review of existing regulations and the promulgation
of new regulations, section 3(a) of Executive Order 12988, ``Civil
Justice Reform,'' 61 FR 4729 (February 7, 1996), imposes on Federal
agencies the general duty to adhere to the following requirements: (1)
Eliminate drafting errors and ambiguity; (2) write regulations to
minimize litigation; (3) provide a clear legal standard for affected
conduct rather than a general standard; and (4) promote simplification
and burden reduction. Section 3(b) of Executive Order 12988
specifically requires that Executive agencies make every reasonable
effort to ensure that the regulation: (1) Clearly specifies the
preemptive effect, if any; (2) clearly specifies any effect on existing
Federal law or regulation; (3) provides a clear legal standard for
affected conduct while promoting simplification and burden reduction;
(4) specifies the retroactive effect, if any; (5) adequately defines
key terms; and (6) addresses other important issues affecting clarity
and general draftsmanship under any guidelines issued by the Attorney
General. Section 3(c) of Executive Order 12988 requires Executive
agencies to review regulations in light of applicable standards in
sections 3(a) and 3(b) to determine whether they are met or it is
unreasonable to meet one or more of them. DOE has completed the
required review and determined that, to the extent permitted by law,
the proposed rule meets the relevant standards of Executive Order
12988.
G. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA)
requires each Federal agency to assess the effects of Federal
regulatory actions on State, local, and Tribal governments and the
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531).
For a proposed regulatory action likely to result in a rule that may
cause the expenditure by State, local, and Tribal governments, in the
aggregate, or by the private sector of $100 million or more in any one
year (adjusted annually for inflation), section 202 of UMRA requires a
Federal agency to publish a written statement that estimates the
resulting costs, benefits, and other effects on the national economy.
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to
develop an effective process to permit timely input by elected officers
of State, local, and Tribal governments on a proposed ``significant
intergovernmental mandate,'' and requires an agency plan for giving
notice and opportunity for timely input to potentially affected small
governments before establishing any requirements that might
significantly or uniquely affect small governments. On March 18, 1997,
DOE published a statement of policy on its process for
intergovernmental consultation under UMRA. 62 FR 12820; also available
at http://energy.gov/gc/office-general-counsel. DOE examined this
proposed rule according to UMRA and its statement of policy and
determined that the rule contains neither an intergovernmental mandate,
nor a mandate that may result in the expenditure of $100 million or
more in any year, so these requirements do not apply.
H. Review Under the Treasury and General Government Appropriations Act,
1999
Section 654 of the Treasury and General Government Appropriations
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family
Policymaking Assessment for any rule that may affect family well-being.
This rule would not have any impact on the autonomy or integrity of the
family as an institution. Accordingly, DOE has concluded that it is not
necessary to prepare a Family Policymaking Assessment.
I. Review Under Executive Order 12630
DOE has determined, under Executive Order 12630, ``Governmental
Actions and Interference with Constitutionally Protected Property
Rights'' 53 FR 8859 (March 18, 1988), that this proposed regulation, if
adopted, would not result in any takings that might require
compensation under the Fifth Amendment to the U.S. Constitution.
J. Review Under Treasury and General Government Appropriations Act,
2001
Section 515 of the Treasury and General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most
disseminations of information to the public under guidelines
established by each agency pursuant to general guidelines issued by
OMB. OMB's guidelines were published at 67 FR 8452 (February 22, 2002),
and DOE's guidelines were published at 67 FR 62446 (October 7, 2002).
DOE has reviewed this proposed rule under the OMB and DOE guidelines
and has concluded that it is consistent with applicable policies in
those guidelines.
K. Review Under Executive Order 13211
Executive Order 13211, ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355
(May 22, 2001), requires Federal agencies to prepare and submit to OMB,
a Statement of Energy Effects for any proposed significant energy
action. A ``significant energy action'' is defined as any action by an
agency that promulgated or is expected to lead to promulgation of a
final rule, and that: (1) Is a significant regulatory action under
Executive Order 12866, or any successor order; and (2) is likely to
have a significant adverse effect on the supply, distribution, or use
of energy; or (3) is designated by the Administrator of OIRA as a
significant energy action. For any proposed significant energy action,
the agency must give a detailed statement of any adverse effects on
energy supply, distribution, or use should the proposal be implemented,
and of reasonable alternatives to the action and their expected
benefits on energy supply, distribution, and use.
This regulatory action to amend the test procedure for measuring
the energy efficiency of battery chargers is not a significant
regulatory action under Executive Order 12866. Moreover, it would not
have a significant adverse effect on the supply, distribution, or use
of energy, nor has it been designated as a significant energy action by
the Administrator of OIRA. Therefore, it is not a significant energy
action, and, accordingly, DOE has not prepared a Statement of Energy
Effects.
[[Page 46865]]
L. Review Under Section 32 of the Federal Energy Administration Act of
1974
Under section 301 of the Department of Energy Organization Act
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the
Federal Energy Administration Act of 1974, as amended by the Federal
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA)
Section 32 essentially provides in relevant part that, where a proposed
rule authorizes or requires use of commercial standards, the notice of
proposed rulemaking must inform the public of the use and background of
such standards. In addition, section 32(c) requires DOE to consult with
the Attorney General and the Chairman of the Federal Trade Commission
(FTC) concerning the impact of the commercial or industry standards on
competition.
Certain of the proposed amendments would incorporate testing
methods contained in the following commercial standards: IEC Standard
62301 ``Household electrical appliances--Measurement of standby
power.'' DOE has evaluated these testing standards and believes that
the IEC standard complies with the requirements of section 32(b) of the
Federal Energy Administration Act, (i.e., that they were developed in a
manner that fully provides for public participation, comment, and
review). DOE is, however, consulting with the Attorney General and the
Chairwoman of the FTC concerning the effect on competition of requiring
manufacturers to use the test method in this standard.
M. Description of Material Incorporated by Reference
DOE previously adopted instrumentation resolution and measurement
uncertainty requirements for testing battery chargers identical to
those in the IEC 62301 standard and codified these requirements at 10
CFR part 430, subpart B, Appendix Y on June 1, 2011. 76 FR 31750. The
IEC published Edition 2.0 of IEC 62301 in January 2011, which is
available from the American National Standards Institute, 25 W. 43rd
Street, 4th Floor, New York, NY 10036 or at http://webstore.ansi.org/.
This revised version of the testing standard refined the test equipment
specifications, measuring techniques, and uncertainty determination to
improve the method for measuring loads with high crest factors and/or
low power factors, such as the low power modes typical of battery
chargers operating in standby mode. These provisions were contained in
Section 4 of IEC 62301, with informative guidance provided in Annex B

(e) Basic model compliance. DOE will evaluate whether a basic model
complies with the applicable energy conservation standard(s) based on
testing conducted in accordance with the applicable test procedures
specified in parts 430 and 431 of this chapter, and with the following
statistical sampling procedures:
(1) For products with applicable energy conservation standard(s) in
Sec. 430.32, and commercial prerinse spray valves, illuminated exit
signs, traffic signal modules and pedestrian modules, commercial
clothes washers, and metal halide lamp ballasts, DOE will use a sample
size of not more than 21 units and follow the sampling plans in
[[Page 46868]]
appendix A of this subpart (Sampling for Enforcement Testing of Covered
Consumer Products and Certain High-Volume Commercial Equipment).
(2) For automatic commercial ice makers; commercial refrigerators,
freezers, and refrigerator-freezers; refrigerated bottled or canned
vending machines; and commercial HVAC and WH equipment, DOE will use an
initial sample size of not more than four units and follow the sampling
plans in appendix B of this subpart (Sampling Plan for Enforcement
Testing of Covered Equipment and Certain Low-Volume Covered Products).
(3) If fewer than four units of a basic model are available for
testing when the manufacturer receives the notice, then:
(i) DOE will test the available unit(s); or
(ii) If one or more other units of the basic model are expected to
become available within 30 calendar days, DOE may instead, at its
discretion, test either:
(A) The available unit(s) and one or more of the other units that
subsequently become available (up to a maximum of four); or
(B) Up to four of the other units that subsequently become
available.
(4) For battery chargers, DOE will use a sample size of not more
than 21 units and follow the sampling plan in appendix D of this
subpart (Sampling Plan for Enforcement Testing of Battery Chargers).
(5) For distribution transformers, DOE will use an initial sample
size of not more than five units and follow the sampling plans in
appendix C of this subpart (Sampling Plan for Enforcement Testing of
Distribution Transformers). If fewer than five units of a basic model
are available for testing when the manufacturer receives the test
notice, then:
(i) DOE will test the available unit(s); or
(ii) If one or more other units of the basic model are expected to
become available within 30 calendar days, the Department may instead,
at its discretion, test either:
(A) The available unit(s) and one or more of the other units that
subsequently become available (up to a maximum of five); or
(B) Up to five of the other units that subsequently become
available.
(6) Notwithstanding paragraphs (e)(1) through (4) of this section,
if testing of the available or subsequently available units of a basic
model would be impractical, as for example when a basic model has
unusual testing requirements or has limited production, DOE may in its
discretion decide to base the determination of compliance on the
testing of fewer than the otherwise required number of units.
(7) When DOE makes a determination in accordance with section
(e)(6) to test less than the number of units specified in paragraphs
(e)(1) through (4) of this section, DOE will base the compliance
determination on the results of such testing in accordance with
appendix B of this subpart (Sampling Plan for Enforcement Testing of
Covered Equipment and Certain Low-Volume Covered Products) using a
sample size (n1) equal to the number of units tested.
(8) For the purposes of this section, available units are those
that are available for distribution in commerce within the United
States.
