Example_Di​schargePul​seEstimati​on code another data adaptation

Hello everyone,

We are having trouble applying Example_DischargePulseEstimation code to the HPPC data we have.

open ('Example_DischargePulseEstimation.m')

After the data fitting process, the data and simulation are not fitting together. In example code data and simulation are fitting. Our data are not fitting. You can see in the below figure the sample data and our data images.

Can you help with this problem?

Thank you.

Hi Gulsum Gozde,

I understand that you are facing data fitting issues while trying to run 'Example_DischargePulseEstimation.m' with your HPPC data.

Since the data and simulation are not fitting together, you can try the following steps to address the issue:

1. Examine the data for any irregularities, outliers, or measurement errors.
2. Verify the input parameters such as initial guesses, bounds and constraints that the functions use. Adjusting these parameters according to your HPPC data might improve the fitting accuracy.
3. Try to increase the data points in your HPPC dataset if possible. More data points can assist in better capturing the underlying behavior of the battery.

You can also refer to the following MATLAB answer for more steps on improving the fitting process:
