SYSTEMS AND METHODS TO CAPTURE AND UTILIZE TEMPERATURE INFORMATION IN A BATTERY SYSTEM

摘要

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.

主权项

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 configured to determine a subdivision electrical parameter associated with a first subdivision selected from among of the plurality of subdivisions; a thermal measurement system 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 and the thermal parameter.
