The IEEE will revise its laptop battery standard, coded IEEE 1625, which was
approved back in 2004 as part of the "Livium" family of battery standards. The
revised standard seeks to improve overall performance, make systems more
reliable and address concerns over the recent laptop battery
fiasco.
IEEE 1625 adopts a systems approach by addressing the battery envelope from
cells to the mobile computers they power, both alone and in concert. It
encompasses such areas as battery pack electrical and mechanical construction,
cell chemistries, packaging, pack and cell controls, and overall system
considerations.
“In revising IEEE 1625 to further safeguard the reliability of
these batteries, we will leverage the streamlined corporate standards process
and incorporate lessons learned in developing the IEEE 1725 standard for
cellular telephone batteries,” says Edward Rashba, Manager, New
Technical Programs at the IEEE-SA. “We have an opportunity to
further strengthen the Livium portfolio, which already incorporates hundreds of
man-hours of technical work and represents consensus views on best practices
from leading industry experts.”
The update looks to guide the industry in planning and implementing controls
for battery design and manufacture. It also defines approaches for evaluating
and qualifying such batteries, verifying their quality and reliability, and
educating and communicating with end users.
“The 1625 update will be a global effort,” says
Rashba. “The leading laptop OEMs and battery manufacturers such as
Apple,
Dell,
Gateway, Hewlett-Packard, IBM, Lenovo, Panasonic, Sanyo,
Intel and Sony have indicated
strong interest to participate.”
The group will meet bi-monthly in the U.S. and Asia, with
project completion expected within 18 months. The first working group meeting is
scheduled for November 15-16 at the Intel in Santa Clara, California. A
follow-on meeting is planned in Japan for January 16-18 of next year.
