APPENDIX 7B. UNIT ENERGY CONSUMPTION FOR BATTERY CHARGERS AND

EXTERNAL POWER SUPPLIES

This appendix to chapter 7 of the p reliminary technical support d ocument (TSD) for the

b attery chargers (BCs) and external p ower supplies (EPSs) energy conservation standards

rulemaking contains typical annual unit energy consumption values (UECs) for BCs and EPSs.

Reference-case UECs are displayed by candidate standard level (CSL) for each Class-A EPS and

BC product class and application. The application-level UECs are inputs to the life-cycle cost

and payback period analyses, while the shipment-weighted-average UECs shown in the bottom

row of each table are inputs to the national impact analysis. Chapter 7 contains detailed

explanations of how these UECs were calculated.

Table 7B. 1 through Table 7B. 7 contain application-level UECs and weighted average

UECs for Class A EPSs.
