What happens after I drop a Battery Cycle file?
The measurement file is parsed into cycle rows and converted into graphs. From there, the workspace helps you review Cycle Performance, Charge-Discharge Profile, and Data Review evidence.
Charge-Discharge Cycling
Battery Cycle Analysis
Convert battery charge-discharge cycle files into graphs, then review Cycle Performance, Charge-Discharge Profile, and Data Review workflows in one workspace.
Open Battery Cycle Analysis Tool
Supported formats
.csv, .txt, .tsv
Available analysis features
- Cycle Performance
Use cycle and charge/discharge capacity rows to calculate discharge capacity and coulombic efficiency by cycle, then review retention and abnormal cycles.
Cycle Performance metrics depend on parsed cycle indices, charge/discharge direction, and capacity units; review sparse or missing cycles before reporting retention.
- Charge-Discharge Profile
Group voltage-capacity rows by cycle to compare first and latest discharge curves, voltage plateau shifts, and aging trends.
Charge-discharge profiles depend on grouped cycle rows and capacity units; compare row coverage before interpreting plateau shifts or aging trends.
- Data Review
Review cycle index and row counts to check missing cycles, sparse cycles, and single-cycle fallback before trusting cycle metrics.
Data Review is the quality gate for cycle metrics; check row counts, missing cycles, and single-cycle fallback before exporting results.
What this tool can review
- Cycle parsing
Load CSV/TXT/TSV files with cycle, voltage, current, capacity, and optional time, temperature, or energy columns.
- Cycle Performance
Calculate discharge capacity, coulombic efficiency, and capacity-retention candidates by cycle.
- Charge-Discharge Profile
Compare first and latest discharge voltage-capacity curves to review voltage plateau shifts and aging trends.
- Data Review
Review point counts, missing cycles, sparse cycles, and single-cycle fallback evidence before exporting results.
Typical use cases
- Review charge-discharge cycle files before preparing capacity and efficiency figures.
- Compare discharge capacity, coulombic efficiency, and capacity retention by cycle.
- Compare first and latest discharge voltage-capacity profiles for plateau shifts and aging trends.
- Check parsed row counts and cycle coverage before trusting cycle metrics.
FAQ
Can I review capacity retention and coulombic efficiency?
Yes. When charge and discharge capacity rows are available, Cycle Performance reports discharge capacity, coulombic efficiency, and retention candidates by cycle.
How are my measurement files handled?
Files uploaded to this analysis tool are processed in the current browser session for graph conversion and analysis. The tool does not send files outside or save them without user permission.
Supported workflow
- Graph Conversion turns supported battery cycle text files into voltage and cycle graph views.
- Cycle Performance reviews discharge capacity, coulombic efficiency, and capacity-retention candidates by cycle.
- Charge-Discharge Profile compares first and latest discharge curves when suitable capacity rows exist.
- Data Review keeps row count, cycle coverage, and sparse-cycle evidence visible before comparing or exporting results.
