Subject: FINAL HP Ex Parte Memo on Proposed Rulema king for Battery Chargers and External Power

Supplies

On behalf of HP, the following is our final submission for the public comment solicitation. Apologies for

the additions.

This following notes summarize the discussion that HP held via teleconference with the Department of

Energy on April 10, 2012 as well as our views on the proposed rule:

Hewlett

‐ Packard Company (HP) appreciates the opportunity to comment on the new DOE rulemaking

for Battery Chargers and External Power Supplies. Thank you for taking the time to speak with us. HP

believes that existing voluntary Market Access Requirements, such as EPEAT and ENERGY STAR, are the

most effective mechanism for improving energy efficiency of IT products, but we understand the

approach of regulating mandatory minimum efficiencies to address poor performing products. HP is a

large manufacturer of PCs, Displays, Printers, Multi

‐ function devices and Networking equipment. We

have completed an initial assessment of the proposed rulemaking and its potential impact.

For Battery Chargers, HP recommends the following:

 DOE should consider the efficiency limits for Class 1 Inductive Chargers. We believe this limit is

unfeasible for higher Battery Energy products, and could stifle innovation in certain product

categories. One suggestion is to revise the Class 1 efficiency limit formula so it scales by Battery

Energy. Another suggestion is to eliminate a separate category for Inductive chargers and have

these chargers classified in other Categories (ie 2, 3 or 4) based on Battery Voltage.

 We recommend that the DOE reconsiders the efficiency limits for Class 8 Low voltage DC input

Chargers. We believe this limit is unfeasible for USB charging of higher Battery Energy products,

and could stifle innovation in certain product categories. One suggestion is to revise the Class 8

efficiency limit formula so it scales by Battery Energy.

For External Power Supplies (EPSs), HP recommends the following:

 New efficiency limits for Class A EPSs were unexpected. We are still working to understand and

assess the potential impact with our EPS suppliers and product teams.

 The combination of new efficiency limits, a July 1, 2013 compliance date and compliance based

on the use of date of importation for products manufactured outside the US, make these rules

very challenging for our product categories.

 A phased approach, with efficiency limits correlating with the International Roman Numeral V

for the July 1, 2013 compliance date, combined with an effort to develop a new efficiency

standard (with input from Industry and EPS manufacturers) which would start as a voluntary

Market Access requirement, perhaps incorporated in an upcoming ENERGY STAR specification

revision.

 The current rules appear to favor domestic manufacturers. HP recommends the use of

Worldwide Date of Manufacturing with five year exemption for Spare parts for EPSs

manufactured before the Compliance date. This would alleviate significant inventory issues

associated with the current proposed rules for products manufactured outside the US.
