1. A system to capture and utilize temperature information in a battery pack comprising a plurality of subdivisions, the system comprising: a battery pack comprising a plurality of subdivisions; an electrical measurement system in electrical communication with the battery pack and configured to determine a subdivision electrical parameter associated with a first subdivision selected from among of the plurality of subdivisions; a thermal measurement system in thermal communication with the battery pack and configured to determine and track a thermal parameter associated with the first subdivision over a plurality of charge and discharge cycles of the battery pack; and a battery model configured to estimate a characteristic of the first subdivision based at least in part upon the subdivision electrical parameter, the thermal parameter, and a geometry of the first subdivision, to estimate a second thermal parameter of a second subdivision based upon a location of the second subdivision within the battery pack and based on the estimated characteristic of the first subdivision and to estimate a subdivision life variation between the first subdivision and the second subdivision; wherein the battery model comprises a Monte Carlo simulation.
