DoE Battery Charger Testing.
Ensure compliance to mandatory DoE regulations for your battery charger systems.

Battery chargers are used by all residential or commercial devices that are powered by batteries. As defined in the Code of Federal Regulations (CFR), “battery charger” means a device that charges batteries for consumer products, including battery chargers embedded in other consumer products. Examples of devices which use battery chargers include mobile phones, laptop computers, two-way radios, emergency backup lighting.

As battery chargers currently operate in three modes (No-battery, Maintenance, and Active), in order to ensure energy savings during actual use, it is important that battery chargers be efficient in all three modes of operation. The amount of time spent in each mode varies significantly among products, and as such, studies have shown that products are often inefficient in any or all three operation modes.

The Department of Energy (DoE) has established regulations on certification, compliance, and enforcement in the CFR at 10 CFR 429 to ensure that all products manufactured or imported into the U.S. are designed to operate efficiently and to waste less energy. If you manufacture or sell battery chargers or products with embedded battery charger systems, your products must be compliant with the DoE’s Energy Conservation Standards to be sold or distributed in the United States. Failure to comply with the new law will result in products that cannot be legally sold in the U.S.

MET Labs is a global leader in energy efficiency testing & certification and is experienced with helping major manufacturers meet the requirements of global energy efficiency programs. We can help battery charger manufacturers and distributors understand the complex DOE regulations, perform required testing, and help you ensure compliance to the mandatory test method. MET can also tests and certify products to energy efficiency requirements for the EPA’s ENERGY STAR® program, Natural Resources Canada (NRCan), California Energy Commission (CEC), EU CE Marking, and Department of Energy (DOE).
