Disclosed herein are various systems and methods for capturing and utilizing temperature information in a battery pack. An electrical measurement system may be configured to determine a subdivision electrical parameter associated with one or more subdivisions, and a thermal measurement system configured to determine and track a thermal parameter associated with one or more subdivisions. A battery model may utilize the thermal parameter and the electrical parameter to estimate a characteristic of one or more battery subdivisions. In some embodiments, the battery model may further 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 a first subdivision. Some embodiments may further estimate a life assessment of one or more subdivisions based at least in part on the subdivision electrical parameter and the thermal parameter.
