Energy Conservation Program: Test Procedure for Battery Chargers

Краткое содержание

The U.S. Department of Energy (``DOE'') proposes to amend the test procedures for battery chargers to improve test procedure representativeness. The proposal would: Establish a new appendix Y1 that would expand coverage of inductive wireless battery chargers and establish associated definitions and test provisions; establish a new test procedure approach that relies on separate metrics for active mode, stand-by, and off-mode (consequently removing the battery charger usage profiles and unit energy consumption calculation); and update the wall adapter selection criteria. DOE also proposes changes to appendix Y to reorganize two subsections, to clarify symbology and references, to correct an incorrect cross reference and section title, to update the list of battery chemistries, and to terminate an existing test procedure waiver because the covered subject models have been discontinued. DOE further proposes to mirror these changes in the newly proposed appendix Y1. DOE is seeking comment from interested parties on the proposals.
