The U.S. Department of Energy DOE released the final version of the Federal Energy Conservation Regulations for Battery Chargers (BC) on June 13, 2016, and required mandatory implementation on June 13, 2018. This regulation applies to all covered products:

Battery chargers for consumer products, including chargers built into consumer products, wireless chargers used in humid environments

USB charging equipment and other DC power supply charging products

All DC or AC (115V at 60Hz) powered battery chargers, whether manufactured in the US or imported into the US market, must be DOE certified as long as they are within the specified range.

According to the capacity and voltage of rechargeable batteries, the DOE energy efficiency regulations divide battery chargers into 7 different categories, and formulate the unit energy consumption (UEC) limit requirements of the corresponding battery chargers, that is, the annual energy consumption of the battery charger. The unit energy consumption (UEC) of the battery charger is a function formula of the battery energy (Ebatt), which reflects the useless energy consumed by the battery charger in all working modes (that is, the energy consumed in the electric process but not transmitted Energy to the battery).

According to the DOE test regulations 10CFR 430, Subpart B, and Appendix Y respectively test the battery charger’s 24-hour energy consumption, standby mode, maintenance mode, off mode and other states of the battery charger power consumption and battery discharge energy Ebatt, etc., and then according to the corresponding The formula calculates the unit energy consumption UEC of the battery charger, and requires that the unit energy consumption UEC cannot exceed the corresponding limit. Battery chargers manufactured after June 13, 2018 must meet the requirements of the maximum unit energy consumption UEC less than or equal to 10 CFR 430.32(z):
