Systems and methods to capture and utilize temperature information in a battery system

A method of capturing and utilizing temperature information in a battery pack comprising a plurality of subdivisions, the method comprising:

• determining a subdivision electrical parameter associated with a first subdivision selected from among of the plurality of subdivisions;
• determining a thermal parameter associated with the first subdivision;
• and
• generating an estimate of a characteristic of the first subdivision based on the subdivision electrical parameter and the thermal parameter.

A computer system comprising:

• a processor;
• and
• a non-transitory computer-readable medium communicatively coupled with the processor, the non-transitory computer-readable medium storing instructions that, when executed by the processor, cause the processor to;
• simulate a battery model configured to receive an electrical parameter input, a control variable input, and a noise variable input, the battery model further configured to generate for at least one subdivision of the plurality of subdivisions a battery model output comprising at least one of a terminal voltage, a terminal power, a temperature, and a state of charge;
• and
• simulate a battery life model configured to receive the battery model output, and to generate a battery life model output comprising at least one of a capacity variation, a temperature variation, and a resistance variation over a plurality of charge and discharge cycles of the at least one subdivision;
• wherein the battery life model output comprises an input to the battery model.
