IEEE approves rechargeable cell phone battery design and production standard

Paul Boughton

The new standardIEEE Livium1725“Standard for Rechargeable Batteries for Cellular Telephones” is the first to adopt a systems approach in setting uniform criteria for battery designproduction and evaluation.

This development represents the second standard within the IEEE Livium portable battery technology family of standards.

The standard considers cell and battery pack electrical and mechanical constructionprocess controlchemistriescharge and discharge controlsand packaging technologiesamong other areas.

It gives the battery and cell phone industries uniform criteria for creating and qualifying rechargeable battery systems and for verifying battery quality.

It was developed within the IEEE Corporate Standards Program by companies that manufacture battery cellsbattery packs and cell phones.“The proliferation of cell phones and the addition of new functions continue to push demand for high-performance lithium-ion based batteries to new levels” comments Jason HowardChair of the Cellular Battery Standard Working Group and Distinguished Member of the Technical Staff at Motorola.

“IEEE 1725 will help those who make and use such batteries meet the needin a reliable mannerfor greater battery power and energy density. Its overall objective is to improve end-user experience by addressing the entire envelope from battery cells and packs to the handsets they power.”

Standards are developed within the IEEE Corporate Standards Programme in company-based working groups in which each member has one vote. This industry-orientated programme often allows for standards creation in one to two yearsdepending on participant commitment and the use of IEEE support services.

“This standards project included a broad cross section of industry and government stakeholders and great support from the IEEE corporate community” said Chuck AdamsChair of the IEEE Corporate Standards Programme and Program Director of Standards & Open Source Technology at IBM Corporation. “Its success represents what companies and the IEEE-SA can achieve in meeting a true standards need when they join forces.”

The CTIA helped initiate the work on IEEE 1725 and is currently working on a lithium-ion and lithium-ion polymer battery certification programme based on the standard.

IEEE 1725 is sponsored by the Stationary Batteries Committee of the IEEE Power Engineering Society.

The IEEE Standards Associationa globally recognised standards-setting bodydevelops consensus standards through an open process that brings diverse parts of an industry together.

These standards set specifications and procedures based on current scientific consensus.

The IEEE-SA has a portfolio of more than 870 completed standards and more than 400 standards in development.
