## 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)

## Data Format Requirements
Our model expects CSV files with columns:
- `cycle_index`: Cycle number
- `voltage`: Battery voltage (V)
- `current`: Battery current (A)
- `temperature`: Battery temperature (°C)
- `capacity`: Battery capacity (Ah)
