Analysis of Automotive Battery Current Characteristics Using Fuse Terminal Voltage Drop and Its Reliability
초록
영어
This study presents a non-invasive method for current estimation using the voltage drop across automotive MICRO-2 fuses. Unlike conventional techniques that require additional hardware, the proposed approach utilizes the inherent milliohm-level resistance of fuses, enabling current monitoring without circuit modification. Experiments were performed on 7.5[A] A fuses to analyze resistance variations with rating, temperature, and contact position. Based on these results, a current estimation model with temperature and tolerance correction was developed. Validation showed that the optimized resistance model (Ropt) achieved the lowest error (MAE: 0.0197 A, MAPE: 0.84%), demonstrating the feasibility of fuse-based current sensing for real vehicle applications and leakage current diagnostics.
