Battery Chargers

May 15th 2014

On May 15, 2014 the U.S. Department of Energy (DOE) issued a notice of data availability regarding test procedures for battery chargers. DOE completed testing of new battery chargers to supplement its earlier analysis presented in a notice of proposed rulemaking from March 2012. DOE has compared these test results with data reported in the California Energy Commission's (CEC) “Appliance Efficiency Database and has found some inconsistencies. To ascertain the reasons for these inconsistencies, DOE is publishing data from its own testing to solicit feedback from manufacturers on whether there are potential ambiguities in the Federal test procedure with respect to how certain battery chargers are tested when determining the energy usage ratings of these products.
