| # Real Battery Dataset Status | |
| ## Summary | |
| **Fake/Sample Data**: ✅ DELETED | |
| **Real Data Downloaded**: | |
| ### ✅ NASA Datasets (COMPLETED) | |
| - **Source**: https://github.com/huzaifi18/RUL_prediction | |
| - **Files Downloaded**: 6 CSV files (charge and discharge for B0005, B0006, B0007) | |
| - **Location**: `data/nasa/` | |
| - **Converted Files**: 3 files in standard format | |
| - **Location**: `data/nasa_converted/` | |
| - **Format**: ✅ Converted to standard format (cycle_index, voltage, current, temperature, capacity) | |
| - **Files**: | |
| - B0005.csv (168 cycles, 13 KB) | |
| - B0006.csv (168 cycles, 13 KB) | |
| - B0007.csv (168 cycles, 13 KB) | |
| ### ✅ Stanford Datasets (COMPLETED) | |
| - **Source**: https://github.com/petermattia/revisit-severson-et-al | |
| - **Files Downloaded**: 41 CSV files (cell1.csv through cell41.csv) | |
| - **Location**: `data/stanford/` | |
| - **Total Size**: ~30 MB | |
| - **Format**: ⚠️ **DIFFERENT FORMAT** - Matrix format (99 columns, appears to be voltage arrays) | |
| - **Note**: Structure needs verification - columns are numeric values, not cycle_index/voltage/current/temperature/capacity | |
| ### ⏸️ CALCE Datasets (PENDING) | |
| - **Source**: https://ioft-data.engin.umich.edu/calce-battery-datasets/ | |
| - **Status**: Requires manual download from IoFT mirror | |
| - **Format**: CSV/text files | |
| - **Action Needed**: Manual download required | |
| ### 📋 Zenodo Datasets (ANALYZED - RECOMMENDATION PROVIDED) | |
| **Dataset**: Lithium-ion battery degradation: comprehensive cycle ageing data and analysis for commercial 21700 cells | |
| **Total Size**: 49.4 GB | |
| **Zenodo Link**: https://zenodo.org/records/10637334 | |
| #### Available Files: | |
| 1. **experiment_metadata.xlsx** (21.9 KB) | |
| - **Status**: ✅ RECOMMENDED FIRST | |
| - **Reason**: Small metadata file - check structure before downloading large files | |
| 2. **Expt 5 - Standard Cycle Aging (Control).zip** (11.4 GB) | |
| - **Status**: ✅✅ **BEST CHOICE - RECOMMENDED** | |
| - **Reason**: Standard cycling conditions, control baseline, most general purpose | |
| - **Priority**: 1 | |
| 3. **Expt 4 - Drive Cycle Aging (Control).zip** (11.4 GB) | |
| - **Status**: ✅ **GOOD CHOICE - RECOMMENDED** | |
| - **Reason**: Realistic drive cycles, control conditions | |
| - **Priority**: 2 | |
| 4. **Expt 3 - Cathode Degradation and Li-Plating.zip** (12.0 GB) | |
| - **Status**: ⚠️ NOT RECOMMENDED INITIALLY | |
| - **Reason**: Specific degradation mode (cathode degradation, Li-plating) | |
| - **Use**: Specialized analysis only | |
| 5. **Expt 2 - C-based Degradation 2.zip** (6.5 GB) | |
| - **Status**: ⚠️ NOT RECOMMENDED INITIALLY | |
| - **Reason**: Specific chemistry (C-based) | |
| - **Use**: Specialized analysis only | |
| 6. **Expt 1 - Si-based Degradation.zip** (9.1 GB) | |
| - **Status**: ⚠️ NOT RECOMMENDED INITIALLY | |
| - **Reason**: Specific chemistry (Si-based) | |
| - **Use**: Specialized analysis only | |
| #### Recommended Download Strategy: | |
| 1. **First**: Download `experiment_metadata.xlsx` (21.9 KB) to understand data structure | |
| 2. **Priority 1**: Download `Expt 5 - Standard Cycle Aging (Control).zip` (11.4 GB) | |
| 3. **Priority 2** (Optional): Download `Expt 4 - Drive Cycle Aging (Control).zip` (11.4 GB) | |
| 4. **Skip initially**: Expt 1-3 (too specific, save for later analysis) | |
