The internal temperature may be generated using electrochemical impedance spectrometry (EIS). Delta values from the EIS estimations to the cell surface temperature may be generated based on a thermal model of the battery. The thermal model of the battery may be created using probe points on the surface of a test battery, such as thermocouples.",
