Energy Conservation Program for Certain Consumer Appliances: Test Procedures for Battery Chargers and External Power Supplies

The U.S. Department of Energy (DOE) is amending its test procedures for battery chargers and external power supplies. In particular, DOE is inserting a new active mode energy consumption test procedure for battery chargers, which is necessary to develop energy conservation standards for battery chargers as mandated by the Energy Independence and Security Act of 2007 (EISA 2007). DOE is also amending portions of its existing standby and off mode battery charger test procedure by decreasing the required testing time. Further, DOE is amending its active mode single-voltage external power supply test procedure to permit the testing of certain types of external power supplies. Finally, DOE is inserting a new procedure to address multiple-voltage external power supplies, which are not covered under the current single-voltage external power supply test procedure.
