IEEE 1625:2004

New IEEE Standard - Superseded.
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 Li-ion and Li-ion polymer, but future versions of this standard 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.
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. This standard, and its accompanying annexes, provides no guarantee of protection or safety for battery users. This standard sets forth recommendations for design analyses and certain testing procedures. The level of assurance for protection and safety resulting from applying this standard depends on the implementation by the manufacturer/supplier and the actions of the end user. In the recommendations for design analyses contained herein, this standard contemplates reasonable intended use by the end user, but it does not provide a complete guarantee against hazards to the end user, such as fire, explosion, and leakage.
