ECM Battery Model Using ANSYS Fluent

ANSYS Fluent: ECM Battery Model

Here, we explain the simulation of an ECM battery using the ANSYS Fluent Multi-Scale Multi-Dimensional (MSMD) Model. Consider a battery with a cell and positive and negative tabs. It is modeled as an active zone while battery tabs are modeled as passive zones. Chemical reactions only occur in the active zones. To start loading MSMD Model you must use the text command interface. Then the MSMD model is appeared in the tree.  Next, we enable the transient solver and energy equation. Then, we enable the MSMD battery model.

In the options tab we can select equivalent circuit and define electrical load type and specify C rate. We set values for initial state of charge and reference capacity based on the experimental date in the model parameters tab . In the conductive zone tab, we specify active zones and in the electric contact tab we select the battery positive and negative tabs.  Fluent will automatically apply the necessary voltage and current boundary conditions. Then, we specify passive and active materials and set UDS values. Now after thermal conditions and initializations we can run the simulation.

  1. Hi, I have a few questions about this video.

    First of all, thank you for posting it, its very helpful!

    Q1: 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? Would it be possible to release the text files used in the tutorial (ecm-soc01.txt and so on unit 07.txt)

    Q2: In the video you don’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?

    Thank you in advance!

    Regards,

    Tom
