ANSYS Fluent: ECM Battery Model (video)

tom96 · May 10, 2018, 08:10

Hi all, I have a few questions about this video: https://www.youtube.com/watch?v=LwGgB6LgnOc

It's a video posted by "ANSYS How To Videos" called ANSYS Fluent: ECM Battery Model.

Q1(min 1.53):[/U][/B] I don’t understand the content of the text files – used to compute the coefficients – uploaded from the text box. How are they structured? How the values were obtained? (ecm-soc01.txt and so on until 07.txt)

Q2(min 2.06): The video doesn’t show how the mesh was made and the regions named. I tried to replicate the geometry and make the mesh. It works but when I am modifying the MSMD battery model tab in the “Conductive Zones” sections the “e-zone”, “tab_nzone” and “tab_pzone” are not present.

How do you name the zones in order to make them appear in the “Active Components”, “Tab Components” and “Busbar Components”?

Q3: Or does ANSYS directly provides the mesh file? If yes, how can I obtain it?

Even if ANSYS provides these files, could someone explain to me how to name the regions of the battery accordingly? (Q2) I am trying to make my own model.

Thank you in advance!

Regards,

Tom

Q1. The structure is shown at this video 1.35
input files are discharge curves
Q2. you may use any names for your model. all of them should be solid

best regards

Hi Alexander,

Thanks for replying.

Q1:The "strucuture" that you mention at minute 1.35 is not the one that I was talking about. I have uploaded a screenshot (at min 1:57) of the "structure" I was asking about. How are these values obtained?

Q2: Thanks for the reply, it works when I put everything as Solid!

Q3: Anyone has the answer for my question 3?

Regards,

Hi,

I dont know whether ansys provides you the Mesh file.

However, the meshing is the most important thing. It is suggested that the electrical components are grouped into one part and all thermal into one part.So that u can achieve good wuality and continous mesh.

Try with an simple 3 block setup, as u can see in many battery model tutorials, without thermal parts. And try to start from there. You should be able to start from electrical first.
