Does battery parameter file represent characteristics of one cell or the whole module?

I have generated a battery module of 196 cylindrical cells arranged in an array of 14 series connected parallel assemblies each having 14 cells with thermal effects using the buildBattery command in MATLAB Simscape R2022b. On observing the battery pack parametrization file I realized that the thermal mass is mentioned both in the ParallelAssmebly section as ParallelAssemblyType1.thermal_mass and in the Module section as Module1.thermal_mass. My doubt is, do these parameters represent cell level parameters or the ParallelAssembly and Module respectively. That being said, does one need to manually calculate the thermal mass for the whole system and input the value in the paramtere file or does the program calculate it for the whole module/ battery pack from the cell level during the simulation? Does this factor then also apply to other paramters in the Module and Parallalel Assembly section of the parameter file?

Thanks in advance :)

Hi Dikshant,

I understand that you want to know whether the parameters represent characteristics of one cell or the entire module.

As per the documentation, it represents the thermal mass of a single cell. Please refer to the documentation for more information. I hope this helps.

Hi Balavignesh,

Yeah I also realized it later, thanks for the help ;)
