Where do the thermal properties of the generic battery model come from?

1 view (last 30 days)
The generic battery model (Electrical/Specialized Power Systerms/Electric Drives/Extra Sources/) is capable of recieving an ambient temperature and puting out a cell temperature. The battery has a thermal resistance measured in degrees C per Watt, but how is this converted into the cell temperature? Is thermal mass of the battery determined by the voltage and chemistry? Where does the thermal mass come from?
