Energy Conservation Program: Test Procedures for Battery Chargers

The U.S. Department of Energy (DOE) is proposing to revise its test procedure for battery chargers established under the Energy Policy and Conservation Act of 1975, as amended (EPCA). These proposed revisions, if adopted, would harmonize the instrumentation resolution and uncertainty requirements with the second edition of the International Electrotechnical Commission (IEC) 62301 standard and other international standards for measuring standby power. Additionally, the proposed amendments would update and propose new battery selection criteria for multi-voltage, multi-capacity battery chargers, and provide specific steps on how to select a battery for those chargers when more than one battery meets the selection criteria, such as with a multi-chemistry battery charger. The proposal also outlines new provisions for conditioning and discharging lead acid batteries.
