Dynamic Cycling Enhances Battery Lifetime

Dynamic cycling improves battery lifetime compared to constant current cycling. Calendar aging regardless of cycling is identified as the dominant factor in degradation. Constant current cycling does not accurately represent real-world aging in EVs.

Battery chemistries and designs need to be evaluated using more realistic load profiles to better understand aging mechanisms at various levels (chemistry, material, and cell). Consequently, there may be opportunities for improving battery performance and longevity by revisiting aging mechanisms based on realistic cycling conditions.
