Intelligent Predictive Battery Management System for Lithium-Ion Batteries
Researchers from the Department of Mechanical Engineering have designed an Intelligent Predictive Battery Management System (IPBMS) to enhance the longevity, safety, and performance of lithium-ion batteries in e-bikes. The system estimates State of Charge (SoC), State of Health (SoH), and Remaining Useful Life (RUL) simultaneously, providing a holistic battery health assessment. The IPBMS outperforms conventional models by achieving Mean Absolute Error (MAE), Mean Squared Error (MSE), and Root Mean Squared Error (RMSE) of 0.59, 1.28, and 1.13 for SoC; 0.87, 1.50, and 1.22 for SoH; and 1.60, 1.28, and 2.69 for RUL. The system offers actionable insights for charging optimization, early fault detection, energy-saving strategies, and adaptive riding modes, ensuring safer and more efficient battery utilization.
