Battery Datasets for Testing Data Pipelines and Workflow Automation

This record contains battery datasets exported from different cyclers. It is intended to be used for testing and validating battery data pipelines and workflow automation. The datasets cover various battery chemistries, cyclers, export formats, and test types. Some contain common bugs that can occur during testing (e.g. bumping the connection cables) or from software export routines; including data with bugs is intentional, to verify data processing robustness. Version 0.8.0 adds a ten-file Arbin MITS Excel suite spanning five laboratories, both Arbin header dialects, multi-workbook continuation, a multi-sheet export with EIS data, and both monotonic and schedule-resetting accumulator behaviors. Filenames follow the convention `{Provider}__{Cell-ID}__{Date}__{Test}__{Temperature}__{Cycler}[__{Qualifier}].{ext}`. The machine-readable catalog of this record, including per-file download URLs, sizes, licenses, source citations, and the battery-data-format parser id for each file, is `metadata.json`. Refer to the README.md file for a complete overview of the test files and their attributes.
