DATASET EIS DATA PROCESSOR¶
Processes Electrochemical Impedance Spectroscopy (EIS) dataset columns by separating real and imaginary impedance components, mapping state-of-charge and cell identifiers, optionally digitizing the impedance curves to a fixed number of points, and optionally optimizing the resulting representation. Use this worker to prepare raw EIS tabular data for battery modelling or further analysis workflows.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Dataset | dataset_1 | dataset | — | Input tabular dataset containing raw EIS measurements; must include columns for real and imaginary impedance components as well as SOC and cell identifiers. | |
| Imaginary Data Column Prefix | im_prefix | text | — | Column-name prefix that identifies imaginary-part impedance columns in the dataset (e.g. ‘Im_’); leave blank if imaginary columns carry no shared prefix. | |
| Real Data Column Prefix | rl_prefix | text | — | Column-name prefix that identifies real-part impedance columns in the dataset (e.g. ‘Re_’); leave blank if real columns carry no shared prefix. | |
| SOC Column | soc_col | text | — | Name(s) of the column(s) representing State-of-Charge values; supports multiple selections driven by the input dataset column list. | |
| Cell Column | cell_col | text | — | Name(s) of the column(s) identifying individual battery cells; supports multiple selections driven by the input dataset column list. | |
| Ref Cell Value | ref_col_value | text | 50 | Reference cell identifier value used to anchor or normalise impedance across cells; defaults to 50. | |
| Number of Points to Digitize | digitize | text | 10 | Number of evenly-spaced points to which each EIS curve is re-sampled (digitized); defaults to 10 — increase for higher curve fidelity, leave null to skip digitization. | |
| Optimize | optimize | string | no | Optional optimization mode or parameter string applied after digitization; leave null to skip the optimization step. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| dataset_drop_columns_output_1 | dataset_drop_columns_output_1 | dataset | Processed EIS dataset with separated, optionally digitized and optimized real/imaginary impedance columns, ready for battery modelling or downstream ML workflows. |
