US 2021/0333084 A1 · Systems And Methods For Detecting Battery System Swelling In Information Handling Systems

Abstract

Systems and methods may be implemented separately from (and external to) a battery system to detect swollen battery system components within a chassis enclosure of the information handling system, without any physical contact with the battery cells or battery system, and without requiring premature opening of the information handling system chassis enclosure to inspect for battery system swelling. A system user may be automatically warned of detected battery system swelling and/or battery system charging may be automatically terminated upon detected battery system swelling so that information handling system failure and/or system service costs that would otherwise be expended to repair damage caused by swollen battery system components may be prevented.

Dependent claims

A method, comprising detecting swelling of a battery system contained within a chassis enclosure of an information handling system without physically contacting the battery, the method further comprising:

sensing a proximity of the battery system to a first location within the chassis enclosure, the first location being separate from and external to the battery system;
detecting swelling of the battery system by determining if the sensed proximity of the battery system indicates existence of battery system swelling;
and
taking at least one first action only upon determining swelling of the battery system exists, and not taking the at least one first action if no swelling of the battery system is determined to exist.

1 more element

An information handling system, comprising:

a battery system contained within a chassis enclosure;
at least one proximity sensor that does not physically contact the battery system and that is positioned at a first location that is separate from and external to the battery system, the proximity sensor sensing physical proximity of the battery system to the proximity sensor and producing a first signal that is representative of the sensed proximity of the battery system;
and
at least one programmable integrated circuit coupled to receive the first signal from the at least one proximity sensor, the at least one programmable integrated circuit being programmed to:
detect swelling of the battery system by determining if the sensed proximity of the battery system indicates existence of battery system swelling;
and
take at least one first action only upon determining swelling of the battery system exists, and not take the at least one first action if no swelling of the battery system is determined to exist.
