Energy Conservation Program: Test Procedure for Battery Chargers

On August 6, 2015, the U.S. Department of Energy (``DOE'') issued a notice of proposed rulemaking (``NOPR'') to amend the test procedure for battery chargers. This final rule is based on that NOPR. The final rule amends the current test procedure, incorporating changes that will take effect 30 days after the final rule publication date. These changes will be mandatory for product testing to demonstrate compliance with any future energy conservation standards that DOE may adopt and for any representations made regarding the energy consumption or energy efficiency of battery chargers starting 180 days after publication of this rule. In summary, these changes update the battery selection criteria for multi-voltage, multi-capacity battery chargers, harmonize the instrumentation resolution and uncertainty requirements with the second edition of the International Electrotechnical Commission (``IEC'') 62301 standard for measuring standby power, define and exclude back-up battery chargers from the testing requirements of this rulemaking, outline provisions for conditioning lead acid batteries, specify sampling and certification requirements for compliance with future energy conservation standards, and correct typographical errors in the current test procedure.
