Webinar to Discuss Draft 1 Version 2.0 Specification for Battery Charging Systems - December 14, 2010

EPA hosted a webinar to present and solicit stakeholder comment on the previously released Draft 1 Version 2.0 specification for Battery Charging Systems (BCSs). During the webinar, several stakeholders expressed concern regarding the proposed timeline for development of the ENERGY STAR BCSs specification and requested that EPA delay its process until DOE completed portions of its standard development work.

EPA proposes to delay development of portions of the specification that would be impacted by the DOE test procedure and standard for consumer BCSs. Please note, however, that specification development relating to definitions, scope, nonactive power allowance, additional environmental benefits, and industrial BCSs will continue as scheduled, with comments due by January 15, 2011.
