ANALYSIS

8C.1 I NTRODUCTION

There are a number of end

- use applications (“applications”) encompassed by each

representative unit examined in the analysis, and this can create a wide range of life

- cycle cost

(LCC) and payback period (PBP) results within each representative unit . This is because many

of the same external power supply (E PS ) or battery charger (B C) specifications can be used for a

variety of applications. S ince many of the inputs to the life

- cycle cost (L CC ) model are

dependent on the particular application, such as product lifetime, DOE considers an array of

popular applications when evaluating each representative unit.

8C.2 END

- USE APPLICATION SELE CTION METHODOLOGY

DOE compiled its list of relevant applicatio ns for the LCC analysis based on the total

shipments of an application within a representative unit’s output power or battery energy and

voltage range for EPSs and BCs, respectively. DOE defines the battery energy and voltage range

similarly to the product class delineations, while it defines the output power range as the

midpoint between two representative units’ values for output power. For example, given three

Class A EPS r epresentative units at 2.5, 18, and 60 Wat ts (W) of output power, the 18W unit

would consider applications that have an output power between 10 to 39W. This is because 10W

is the midpoint between 2.5W and 18W, and 39W is the midpoint between 18W and 60W.

Using these range definitions, DOE classifies the relevant applications for each representative

unit and calculates the total shipment s for each application.

DOE then collected all the relevant information needed as inputs for each of these

applications. This data includes shipments, lifetime, markups, unit energy consumption (UEC),

and market share at each CSL. These inputs are explai ned in more detail in chapters 6, 7, and 10

of the preliminary analysis.

8C.3.1 Class A External Power Supplies

Table 8C. 3.1 through Table 8C.3.4 summarizes DOE’s findings for the applications

associated with Class A EPSs. Each representative unit contains multiple ap plications so the

representative units are shown separately. While each representative unit may contain 10 or

more relevant applications, this appendix only shows data for the top nine applications for each

representative unit. These nine applications comprise over 98- percent of total shipments for a

representative unit. For further detail on application data, including the calculation of UECs,

please see chapter 7 of the TSD.8C-2

### 8C.3.2 Battery Chargers

Table 8C. 3.6 through Table 8C.3.10 summarizes DOE’s findings for the applica tions

associated with BCs. Each representative unit contains multiple applications so the

representative units are shown separately. While each representative unit may contain 10 or

more relevant applications, this appendix only shows data for the top 10 applications for each

representative unit. These 10 applications comprise between 93- to 100-percent of total

shipments for a represe ntative unit.8C-5 

### DOE conducted an LCC analysis for two sets of BC engineering outputs using

manufacturer provided data and data collected through testing and teardowns (“ test/teardown ” ).

The application

- specific data for each of these data types are identical except for the UEC data

, which is shown separately for manufacturer data and test/teardown data. For further detail on

application data, including the calculation of UECs, please see chapter 7 of the TSD.

DOE also examined LCC results for the battery charger product classes that were scaled

rather than directly analyzed as a representative unit. Table 8C. 3.11 through Table 8C. 3.14

summarizes DOE’s findings for the applications associated with these scaled BC product classes.

Each product class contains multiple applications so the product classes are shown separately.

While each product class may contain 10 or more relevant applications, this appendix only

shows data for the top 10 applications for each product class. These 10 applications comprise

between 98- to 100-percent of total shipments for a product class. D OE examined manufacturer

data for the scaled product classes, but not test/teardown data.8C- 10

### 8C.4 END

- USE APPLICATION SAMPLING

DOE uses the list of relevant applications for each representative unit to approximate the

input variables for that unit. To do this, DOE weights each application within a given

representative unit by that application’s shipments as a percentage of the total shipments for the

unit. DOE then uses these weighted inputs for the LCC calculations. DOE believes an

application’s shipments are an accurate index of consumer purchases relative to other

applications within a year. While some of DOE’s analyses in this preliminary analysis focus on

an application’s install base to approximate the level of ownership for a given product , DOE

finds that shipments better reflect consumer purchasing events within a year, which is the object

of concern in the LCC and PBP analysis.

In the Monte Carlo simulation analysis, DOE samples an application from each

representative unit for each trial that is run. The applications are sampled based on their

shipment-weighted probabilities. All of the application’s input variables are used when it is

selected in a trial. These input variables include lifetime, markups, UEC, and market share at

each CSL. The resulting LCC findings are thus made up of multiple trials that account for

discrete input sets for each applicatio n, which are then averaged over the number of trials

conducted.

In the sample calculation, however, DOE utilizes only one set of inputs per representative

unit. These inputs are generated by using a shipment- weighted average across applications for

each of the input types. Thus, the resulting inputs account for each of the applications in8C- 14 

### proportion to the application’s weighting. Table 8C. 4.1 through Table 8C. 4.2 shows the

shipment-weighted results for each input. The UECs for BC representative units are shown

separately for manufacturer data and test/teardown data.

As explained in chapter 7, the shipment-weighted UECs for some BC representative units

do not precisely align with the nominal UEC used to define a CSL. This is due to slight

differences in the application -specific usage and loading profiles compared to the average usage

and loading profile used to determine CSLs. Excluding the Test/Teardown unit for Low Energy,

Low Voltage BCs, the difference in LCC savings as a percentage of total life

- cycle cost between

these two methodologies ranges from 0- to 1.7- percent. DOE notes this discrepancy, but finds

that the discrepancy is within an allowable margin of error for Monte Carlo sampling.

Furthermore, DOE notes the added benefit of being able to examine specific applications rather

than an aggregated average when considering how many products might be impacted by a

standard. For these reasons, DOE used the application-weighted UEC values in its BC analysis,

and it presents these values in Table 8C. 4.2

### DOE also calculated the shipment -weighted inputs for scaled battery charger product

classes. The methodology for calculating these inputs is the same as for the representative units.
