Information handling system multi-cell cantilevered battery

Abstract

A portable information handling system battery pack couples plural flat battery cells to a frame in first and second planes having battery cells of the first plane aligned to extend past battery cells of the second plane in a cantilevered manner. In one embodiment, the battery pack integrates a battery management unit and a wireless charger.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates in general to the field of information handling system integrated power sources, and more particularly to an information handling system multi-cell cantilevered battery.Description of the Related Art[0002]As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and / or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or comm...

AI Technical Summary

Benefits of technology

This patent describes a new system and method for integrating flat battery cells into a portable information handling system. The battery cells are placed in two planes, with one plane offsetting the others in a cantilevered arrangement to improve heat dissipation and component placement. This results in a more efficient and compact battery pack that can offer longer battery life and support additional accessories like wireless charging. Overall, this innovation allows for better performance and overall improved design of portable information handling system battery packs.

Problems solved by technology

End users generally prefer portable information handling systems that have minimal weight for a given display size, however, reducing system weight typically results in reduced processing capabilities.

In addition, component placement tends to face restrictions so that dissipated thermal energy is not concentrated within the housing.

Other component placement restrictions further complicate low Z-height systems, such as placement of antenna to achieve sufficient wireless signal communication and placement of speakers to provide adequate sound quality.

Compromises in component selection and placement to achieve low Z-height tend to impact the end user's experience with the information handling system.

However, during discharge and charge, battery cells release thermal energy that adds to the thermal dissipation difficulty associated with poor airflow within low Z-height housings.
