IEEE Std 1625-2008, IEEE Standard
for Rechargeable Batteries for Portable Computing, was approved
on 26 September 2008. To purchase the standard, visit the
IEEE shop.
Scope
This standard establishes criteria for design analysis
for qualification, quality and reliability of rechargeable
battery systems for portable computing. It also provides
methods for quantifying the operational performance of these
batteries and their associated management and control systems
including considerations for end-user notification. This
standard covers rechargeable battery systems for mobile
computing. The battery technologies covered are limited
to lithium ion and lithium ion polymer, but future versions
of this document may include technologies that are not in
general use at present. Also included are: battery pack
electrical and mechanical construction; system, pack, and
cell level charge and discharge controls; and battery status
communications. The following are addressed: qualification
process; manufacturing process control; energy capacity
and demand management; levels of management and control
in the battery systems; current and planned lithium-based
battery chemistries, packaging technologies, and considerations
for end-user notification.
Purpose
The purpose of this standard is to ensure reliable user
experience and operation of batteries in portable computing
environments. The battery industries need standardized criteria
for design and qualification of rechargeable battery systems
and for verifying the quality and reliability of those batteries.
