| Abstract |
This study analyzes the degradation mechanism of electric vehicle (EV) batteries in a V2G (Vehicle-to-grid) environment. The charging and discharging patterns are designed under two conditions and generate accurate IC (Incremental capacity) curves by using Gaussian weighted Savitzky?Golay filter and KRDI (Keep-raw-data interpolation) to design the optimal V2G patterns. This result provides comprehensive insights into battery degradation patterns in various V2G use scenarios and presents a strong foundation for developing advanced battery management strategies and significantly improving the long-term reliability and efficiency of V2G technology. |
