4.1.4 Chemistry Screen

The chemistry file contains parameters that the simulations use to model the cell and the operating profile. A critical issue is to program a Chemistry ID that matches the cell into the device. Some of these parameters can be viewed in the Data Memory section of the Battery Management Studio.

  1. Press the Chemistry button to select the Chemistry window.

  2. The table can be sorted by clicking the desired column. for example: Click the Chemistry ID column header. Please ensure that the box in the top left corner is selected to ensure that only IT-DZT ChemIDs are available.
  3. Select the ChemID that matches your cell from the table (see Figure 4-4).
  4. Press the Program Selected Chemistry button to update the chemistry in the device.
  5. If the GPCRB tool has been used for low temperature optimization tool Press Program from GPCRB file button to program the Chemdat file. This step is not required.
