Bulletin Title:US Department of Energy (DoE) Proposed Rule for Battery Chargers and External Power Supplies

Requirement Effective:July 1, 2013

Summary Description:

The US Department of Energy (DoE) issued a Notice of Proposed Rulemaking (NOPR) detailing a regulation on “Energy Conservation Standards for Battery Chargers and External Power Supplies”. Within this NOPR, is a plan that would either create limits, or set tighter limits on the efficiency of consumer, commercial, and industrial products that include battery charging systems (BCS) and/or external power supplies (EPS). Any product in scope of the regulation that charges a battery and/or has an EPS would be impacted. The regulation includes provisions for labeling of product, and will most likely require online registration of products with DoE. The likely effective date is July 1, 2013.

Detailed Description:

External Power Supplies:

Efficiency levels for EPS are defined in Table 1. Additionally EPS products would need to be labeled with the Roman Numeral VI.
