Energy Conservation Program: Test Procedures for Battery Chargers and External Power Supplies (Standby Mode and Off Mode)

The Department of Energy (DOE) is amending its test procedures for battery chargers (BCs) and external power supplies (EPSs) to include provisions for measuring standby mode and off mode energy consumption, as directed by the Energy Independence and Security Act of 2007 (EISA 2007). Furthermore, DOE is adding to its single-voltage external power supply test procedure specifications for testing switch- selectable external power supplies. Finally, DOE is extending the current certification reporting requirements to the Class A external power supplies for which Congress established energy efficiency standards in EISA 2007.
