Appearance

4.2 R1 and C1 Validation ​

The R1 and C1 pages show the first polarization branch of the ECM.

Validation Steps ​

  1. Open the R1 page.
  2. Open the C1 page.
  3. Review the trend of each parameter with SOC and temperature.
  4. Confirm that the values are consistent with the fitted pulse response.

Expected Result ​

R1 and C1 should show a physically reasonable trend and should not display abrupt discontinuities.

Acceptance Check ​

  • R1 and C1 are both positive.
  • The trend is smooth and consistent.
  • The values are within the acceptance range defined for the example case.
