Appearance

How is extraction configured? ​

The Configuration tab is used to define the extraction settings and initiate the battery characterization process.

Purpose ​

The Configuration tab allows users to:

  • Configure pulse detection settings.
  • Execute ECM parameter extraction.
  • Review extraction results.

The extraction process uses the uploaded HPPC and OCV datasets to identify battery model parameters.

Extraction Settings ​

The Extraction Settings panel is located on the left side of the screen.

HPPC Pulse Threshold ​

The HPPC Pulse Threshold defines the minimum current magnitude required for pulse detection.

Example:

text
25 A

During characterization, current events larger than the threshold are considered valid HPPC pulses.

Selection Guidelines ​

The threshold should be selected according to the HPPC test current.

General recommendations:

Test CurrentSuggested Threshold
10 A3 – 5 A
20 A5 – 10 A
50 A15 – 25 A
100 A30 – 50 A

The threshold should be high enough to avoid capturing regular charging/discharge or noise as pusle while remaining low enough to capture all valid pulses.

Temperature Selection ​

The Temperature selector allows users to view extraction results for a specific test temperature.

Examples:

  • 25 °C
  • 45 °C
  • 60 °C

Changing the selected temperature updates the displayed characterization results without rerunning the extraction.

Test Type Selection ​

The Type selector determines which characterization dataset is displayed.

Available options:

  • Charge
  • Discharge

This setting is used for result visualization and review.

The selected type does not modify previously extracted parameters.

Running Parameter Extraction ​

To start characterization:

  1. Enter the HPPC Pulse Threshold.
  2. Verify the uploaded datasets.
  3. Click Run Extraction.

The software will automatically:

  • Detect HPPC pulses.
  • Generate OCV-SOC curves.
  • Identify ECM parameters.
  • Perform pulse fitting.
  • Generate characterization results.

Processing time depends on dataset size and system performance.

Extraction Results Panel ​

After extraction is completed, a summary of identified ECM parameters is displayed.

Typical parameters include:

ParameterDescription
R0Ohmic resistance
R1First polarization resistance
C1First polarization capacitance
R2Second polarization resistance
C2Second polarization capacitance

These values represent the currently selected temperature and test type.

Extraction Status ​

The extraction status indicator displays the current processing state.

Possible states include:

  • Ready
  • Running
  • Completed
  • Failed

A successful extraction will display:

text
Status: Completed

​

Expected Outcome ​

After successful extraction:

  • HPPC pulses are identified.
  • OCV characterization is completed.
  • ECM parameters are extracted.
  • Pulse fitting is performed.
  • Characterization results become available in subsequent tabs.

The next tab displays the pulse segmentation results used during parameter identification.
