To determine the DC internal resistance (DCIR) of a cell, run a DCIR test using the DCIR Test.vi.

Equipment

  • PXIe-4051
  1. Use the NI Example Finder to open DCIR Test.vi.
    1. In the LabVIEW window, select Help » Find Examples.
      The NI Example Finder window loads.
    2. Select Toolkits and Modules » Battery Cell Quality » DCIR Test.vi.
      The front panel of the VI loads.
  2. On the front panel of the VI, select the electronic load resource from the HW Resource Name control.
  3. Optional: To perform an automatic self-calibration, enable Self-Calibration?
    Note Before allowing a DUT self-calibration, NI recommends disconnecting the electronic load. Self-calibrating a connected DUT may damage your equipment or lead to inaccurate data.
    1. Set Temperature Delta to trigger self-calibration at a specified temperature differential value.
    2. Set Days to Calibration to trigger self-calibration after a specified number of days since the last calibration.
  4. Enter the DCIR Test Parameters.
    1. Set the Maximum Load Current (A) for the test.
    2. Set the Power Line Frequency (Hz) for the test environment.
  5. Click Run.
After running the VI, view DC Resistance (Ohms) for the measurement result.
