To further boost electric vehicle adoption, vehicle-to-everything (V2X) technology, including vehicle-to-home (V2H) and vehicle-to-grid (V2G) applications, has gained prominence. However, a prevailing concern of owners pertains to the potential acceleration of battery aging associated with V2X deployments. In response to these concerns, this paper presents a systematic approach to quantifying EV battery degradation across various charging strategies. The study conducted battery aging experiments under real-world driving and V2X applications, focusing on the intricate relationships between V2X applications and battery degradation. Results showed that the aging spread between all V2X and reference scenarios was lower than the spread caused by cell-to-cell manufacturing variation under identical conditions. The results of the parameter study reveal that adopting V2X applications, in addition to primary mobility prospects, does not significantly increase battery degradation and can even reduce capacity loss compared to the conventional uncontrolled charging strategy if properly configured.
