Defining the Battery Modules

You define two battery modules—each with four battery cells in series and two in parallel, then you specify the geometry parts for each of the cells in both modules.

To define the battery modules:
  1. Create the first battery module.
    1. Right-click the Batteries > Battery Modules node and select New > User-Defined Battery Module.
    2. Rename the Batteries > Battery Modules > Battery Module node to Battery Module 1.
    3. Select the Battery Module 1 node and set the following properties:
      N Series 4
      N Parallel 2
    4. Expand the Battery Module 1 > Battery Module Cells node, then multi-select all battery module cell sub-nodes and set Battery Cell to User Defined Battery Cell .
    The battery module and all associated battery cell nodes appear with a caution symbol on them—which specifies that they require further set-up. In this case, they require geometry parts to be assigned.

  2. Create the second battery module.
    1. Right-click the Battery Module 1 node and select Copy.
    2. Right-click the Battery Modules node and select Paste.
    3. Rename the copy to Battery Module 2.
Before you assign the battery geometry parts to the battery cells, you need to check that the names of the battery cells all follow the same pattern. Therefore, you rename the geometry part Cell to Cell (1 x 1) for the mapping assignment to work correctly.
  1. Rename the Geometry > Parts > Cell node to Cell (1 x 1).
  2. Assign battery geometry parts to the battery cells in Battery Module 1 using the Assign By Mapping approach.
    1. Right-click the Battery Module 1 node and select Assign Parts to Battery Module Cells by Name.
    2. In the Assign Parts to Battery Module Cells by Name dialog, in the Mapping Inputs group box, set the following:
      Mapping Input Setting
      Parallel Occurrence 2
      Series Occurrence 1
      Parallel Offset -1
      Series Offset -1


    3. In the Available Parts for Assignment group box, select Cell (1x1), Cell (2x1), Cell (3x1), and Cell (4x1).
    4. In the space between the two group boxes, click the arrow pointing to the right.
    5. In the Confirm Assignment of Parts to Cells dialog, click OK.
    6. To match the battery parts correctly to the remaining module 1 battery cells, edit the Mapping Inputs as follows:
      Mapping Input Setting
      Parallel Occurrence 2
      Series Occurrence 1
      Parallel Offset 0
      Series Offset -5
    7. Use the same process as above to assign the corresponding parts to the remaining module 1 battery cells as follows:
      Parts Battery Module Cell
      Cell (5x1) Battery Module 1 Cell 1,0
      Cell (6x1) Battery Module 1 Cell 1,1
      Cell (7x1) Battery Module 1 Cell 1,2
      Cell (8x1) Battery Module 1 Cell 1,3
    8. Click OK.


    9. Click Close.
The Assign Parts to Battery Module Cells by Name tool provides a flexible approach to assigning parts to their respective battery module cells. The option to assign by mapping is useful, however, there is also the option to assign parts to battery module cells manually.
  1. Assign battery geometry parts to the battery cells in Battery Module 2 using the Assign Manually approach.
    1. Right-click the Battery Module 2 node and select Assign Parts to Battery Module Cells by Name.
    2. In the Assign Parts to Battery Module Cells by Name dialog, above the Mapping Inputs group box, select Assign Manually.


    3. In the Assign Parts to Battery Module Cells by Name dialog, select the following parts and battery module cells:
      • Cell (1x2)
      • Cell (2x2)
      • Cell (3x2)
      • Cell (4x2)
      • Cell (5x2)
      • Cell (6x2)
      • Cell (7x2)
      • Cell (8x2)
      • Battery Module 2 Cell 0,0
      • Battery Module 2 Cell 0,1
      • Battery Module 2 Cell 0,2
      • Battery Module 2 Cell 0,3
      • Battery Module 2 Cell 1,0
      • Battery Module 2 Cell 1,1
      • Battery Module 2 Cell 1,2
      • Battery Module 2 Cell 1,3
    4. Click the arrow pointing to the right.


    5. Check that the parts and cells are matched correctly, as shown below.


    6. Click Close.
  2. Save the simulation.
