6、r Portable Computing Working Group was formed to provide a platform based on the experience of industry leaders in cell, battery pack, and systems management, leading to design approaches for portable computing devices. The focus of the standard is on design approaches for reliable operation of port
7、able computing devices and similar rechargeable battery-operated systems. This standard may be relevant to other devices but these were not expressly considered in its development. Figure a presents the need for an approach involving all system components, including the user and environment. It is n
8、ecessary to examine all design margins in combination to understand the effect of multiple fault response on the portable computing device. The standard addresses such questions as: What are the critical operational parameters and how do they change with time and environment? What are the effects of
9、 extremes in temperature, pressure, and impact? A total system view is required to protect the design margins in the various components. The goal of reliability and positive user experience require that design margins be maintained as user patterns, profiles, and duty cycles change. This standard ap
10、plies to rechargeable lithium-ion (Li-ion) and lithium-ion polymer (Li-ion polymer) batteries and battery packs for use in portable computing. Because of the nature of the interactions between the battery and the host device, a system approach must be used in developing an appropriate operating enve
11、lope for the system. The provisions of this standard are intended to provide considerations for design analyses to minimize the occurrence of failures leading to hazards. This standard is a system level standard, as depicted in the conceptual diagram. Overall compliance is dependent on conformity to
12、 each and every subclause of the standard. Compliance with the standard cannot be achieved by any particular portable computing device or subsystem alone, without considering the conformity of all subsystems within the system as well as the user. It is incumbent upon the designers of the host device
13、, battery pack, and cell to review thoroughly their designs, alone and in conjunction with other subsystems, to identify faults that could propagate hazards. Once it has been ascertained that the cell, battery pack, and host device all conform to all their particular subclause requirements, the over
14、all system compliance is not finished until the designer completes a thorough design analysis e.g., design failure mode Figure aConceptual diagram of a mobile computing device and its user -,-,- ivCopyright 2004 IEEE.

Disclaimer Compliance with the provisions of this standard does not imply compliance to the regulatory requirements that are applicable to cell, battery packs, and systems. Care must be used to observe and refer to the applicable regulatory r

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
