Equivalent Circuit Fitting (Beta)
Automatically analyze battery impedance data with the pre-defined model shown below.
Just upload a CSV file and get the fitting result.
Requirements for the input CSV file format:
- Column names for frequency, real part of impedance and imaginary part of impedance should include the words "FREQUENCY(Hz)", "R", and "X", respectively.
- Comma-separated CSV format and semicolon-separated CSV format are supported.
- ZView format (.z file) is also available.
- Download sample input files from here:
comma.csv , semicolon.csv , sample.z
If you are not satisfied with the result, try fitting with the file again and you might get a bit different result.
