Definitions, default model usage, and methodology notes for every dataset column.
Dataset Columns
| Column | Meaning | Data Type | Default Usage | Reason |
|---|---|---|---|---|
| Vehicle_ID | Unique vehicle or battery record identifier. | string | No | Excluded because it is only an identifier and does not provide meaningful predictive information. |
| Car_Model | Electric vehicle model name. | categorical | Yes | Operational context feature. |
| Battery_Type | Battery chemistry, such as NMC or LFP. | categorical | Yes | Battery chemistry can influence degradation behavior. |
| Battery_Capacity_kWh | Battery energy capacity in kilowatt-hours. | numeric | Yes | Capacity may relate to operating stress and degradation. |
| Vehicle_Age_Months | Vehicle age in months. | numeric | Yes | Battery age is a direct degradation-related factor. |
| Total_Charging_Cycles | Total number of charging cycles. | numeric | Yes | More cycles usually indicate more battery wear. |
| Avg_Temperature_C | Average operating temperature in Celsius. | numeric | Yes | Temperature can accelerate battery aging. |
| Fast_Charge_Ratio | Share of charging events using fast charging. | numeric | Yes | Fast charging can affect degradation. |
| Avg_Discharge_Rate_C | Average battery discharge rate. | numeric | Yes | Discharge intensity can affect battery stress. |
| Driving_Style | Driving behavior category. | categorical | Yes | Driving style can influence battery load patterns. |
| Internal_Resistance_Ohm | Battery internal resistance. | numeric | Yes | Internal resistance is strongly related to battery aging. |
| SoH_Percent | State of Health percentage. | numeric | Target | This is the supervised regression target. |
| Battery_Status | Battery condition label. | categorical | No | Excluded by default because it may be derived from SoH_Percent and cause data leakage. |
