Energy Conservation Standards Adopted for Battery Chargers
The Department of Energy is imposing energy conservation standards for battery chargers after having concluded that these standards represent the maximum improvement in energy efficiency that is technologically feasible and economically justified and would result in significant conservation of energy. The effective date of this rule is Aug. 12 but compliance will only be required for covered products manufactured in or imported into the U.S. on and after June 13, 2018.
DOE states that a battery charger is a device that charges batteries for consumer products, including battery chargers embedded in other consumer products. Functionally, a battery charger is a power conversion device used to transform input voltage to a suitable voltage for charging the battery. Battery chargers are used in conjunction with other end-use consumer products, such as cell phones and digital cameras. However, the battery charger definition prescribed by Congress is not limited solely to products that are only powered from AC mains; i.e., products that plug into a wall outlet. Further, battery chargers may be wholly embedded in another consumer product, wholly separate from another consumer product, or partially inside and partially outside another consumer product. While devices that meet the statutory definition are within the scope of this rulemaking, DOE is not setting standards for all battery chargers.
