DOE Issues a Notice of Proposed Rulemaking, Request for Comment and Notice of Public Webinar Pertaining to Test Procedures for Battery Chargers

The U.S. Department of Energy (DOE) has issued a pre-publication Federal Register notice proposing 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.

  • DOE will accept comments, data, and information regarding this NOPR until 60 days after date of publication in the Federal Register. DOE will send a follow-up e-mail once the notice publishes to announce the closing date of the comment period.
