Recent and Ongoing Activities

DOE has published a Federal Register notice final rule amending the existing test procedures for battery chargers to reorganize certain subsections, clarify symbology and references, correct an incorrect cross reference and section title, update the list of battery chemistries, and terminate an existing test procedure waiver because the covered subject models have been discontinued. This final rule also establishes in new appendix Y1 a new a test procedure for battery chargers that expands coverage to include inductive wireless battery chargers and establishes associated definitions and test provisions; establishes a new test procedure approach that relies on separate metrics for active mode, standby mode, and off mode; and updates the EPS selection criteria. The new test procedure Y1 will be used for the evaluation and issuance of updated efficiency standards, as well as to determine compliance with the updated standards, should such standards be established.

  • The effective date of this rule is October 11, 2022
  • The amendments to the current test procedure will be mandatory for product testing starting March 7, 2023.
  • Manufacturers will be required to use the amended test procedure in appendix Y until the compliance date of any final rule establishing amended energy conservation standards based on the newly established test procedure in appendix Y1. At such time, manufacturers will be required to begin using the newly established test procedure in appendix Y1.
