Abstract

Official abstract text for this publication.

System and methods for identifying a weak subdivision in a battery system are presented. In certain embodiments, a system may include a battery pack that includes multiple subdivisions. A measurement system may be configured to determine multiple subdivision electrical parameters associated with the subdivisions. A battery control system may identify a weakest subdivision based one on or more calculated derivative ratios of a subdivision electrical parameter associated with one subdivision of the battery pack relative to a subdivision electrical parameter associated with another subdivision.

First claim

Opening claim text (preview).

The invention claimed is: 1. A system comprising: a battery pack comprising a plurality of subdivisions; a measurement system configured to determine a plurality of subdivision electrical parameters, each subdivision electrical parameter of the plurality of subdivision electrical parameters being associated with one of the plurality of subdivisions; a battery control system communicatively coupled to the measurement system, the battery control system configured to identify a…
