Original Abstract Submitted
A battery includes a battery cell and processing circuitry. The processing circuitry is configured to determine an estimated temperature of the battery cell as a function of various models. The models include a battery cell heat generation model that receives a first input indicative of a battery voltage measurement, a second input indicative of a voltage corresponding to a battery open-circuit voltage (OCV) model, and a third input indicative of a battery current measurement. The models also include a gas gauge and system heat generation model that receives the third input. The models also include a battery and gas gauge heat transfer model that receives a fourth input indicative of a gas gauge temperature measurement.
