U.S. DoE Proposes Tightened External Power Supply Efficiency Requirements

On March 7th, the U.S. Department of Energy issued what may be this year’s most important and far-reaching Notice of Proposed Rulemaking (NOPR). The NOPR, Energy Conservation Standards for Battery Chargers and External Power Supplies, not only presents the first mandatory federal efficiency standards for battery charger systems (BCSs), it also significantly tightens and expands [...]

EC Code of Conduct Requirements for EPSs Get New Life

I had mixed feelings when I received my invitation to attend last week’s workshop on the European Commission’s Code of Conduct (CoC) for External Power Supplies (EPS). I was excited to finally visit the EC’s Joint Research Centre in Ispra, Italy when the weather was nice (over the years, the meetings I’ve attended there have [...]

Mr. Green Sums Up EC Ecodesign Changes for 2011

There have been a number of changes in the Ecodesign Directive for ErPs this year. Hopefully, you’ve read some of the blogs. Some of this year’s stories included: Is the first Ecodesign Directive voluntary agreement around the corner? New Developments for External Power Supply Specs European Commission Moves Forward to Reduce Network Standby Power Waste [...]

Canada Tightens Current Energy Efficiency Regulations, Adds New Product Groups

Last month, Canada expanded its scope towards reducing household energy waste by tightening energy efficiency requirements for some already regulated products while also introducing Minimum Energy Performance Standards (MEPS) for 5 new product groups. Published in the October 12 issue of the Canada Gazette Part II, these amendments to the Energy Efficiency Regulations become effective [...]

US DoE Moves Closer to the Finish Line – New BCS and Expanded EPS Test Standards Published

Last month, the US Department of Energy published amendments to its Battery Charger Systems (BCSs) and External Power Supplies (EPSs) test procedure. This completes an important milestone for the DoE, allowing the focus to turn to the next (and extremely important) part of the EISA2007 BCS and EPS requirement – issuing its first energy conservation [...]

New Developments for External Power Supply Specs

Here’s an update on some recent activity in energy efficiency programs for external power supplies (EPSs) and a chart summarizing the specs. Last month, the European Commission’s Ecodesign Directive tightened its Lot 7 EPS standard from the initial Tier 1 efficiency levels to Tier 2. Notable changes include the reduction of no-load power consumption for [...]
