The study proposes a comprehensive methodology for predicting NEV performance and reliability. It involves data analysis, feature selection, model training, and evaluation. Key features are selected based on their significant impact on NEV performance predictions. The dataset is split into 80% for training and 20% for testing. Advanced ML models are trained and evaluated, with the best-performing models selected for further prediction and analysis. Cross-validation and hyperparameter optimization ensure model generalizability and reliability. This approach aims to address the complexities of high-dimensional sensor data from NEVs, enabling accurate and robust fault detection.
The research utilizes the publicly available Kaggle Fault Diagnosis Dataset for NEVs, focusing on drivetrain component fault detection. This dataset comprises approximately 11,000 rows of high-resolution sensor readings, including voltage, current, motor speed, temperature, vibration, ambient temperature, and humidity. Each entry is annotated with a fault label (Normal, Motor fault, Inverter fault, Battery fault). Preprocessing ensures data cleanliness and consistency, handling missing values by replacing them with the mean, normalizing continuous variables, and processing outliers. Stratified sampling preserves class proportions during the 80/20 train/test split, with MinMax normalization applied only to the training set to prevent data leakage.
The study evaluates several ML and DL models: Logistic Regression, Passive-Aggressive Classifier, Ridge Classifier, Perceptron, Gated Recurrent Unit (GRU), Convolutional Neural Network (CNN), and Artificial Neural Network (ANN). Each model is tailored to specific aspects of NEV fault detection. GRU is designed for sequential data, CNN for thermal anomaly detection, and ANN for complex pattern recognition. Hyperparameter optimization is applied to all models to achieve optimal performance, with settings detailed for each. The proposed GRULogX ensemble integrates GRU with Logistic Regression and other classifiers for enhanced accuracy.
