EV battery durability exceeds previous expectations

Recent research and real-world testing indicate that electric vehicle (EV) batteries are significantly more robust and long-lasting than previously assumed. Studies, including research from Stanford University, suggest that using “dynamic cycles”—simulating real-world driving with varying charging and resting phases—can actually help stabilize internal chemical processes and slow degradation compared to rigid laboratory testing.

Data regarding used EVs shows that under normal driving conditions, battery capacity typically does not drop below 70 percent until well after the 200,000-kilometer mark. This contradicts common concerns regarding rapid value depreciation in the used market.

A practical test of a 2022 Tesla Model 3 equipped with a Lithium Iron Phosphate (LFP) battery demonstrated this durability. After approximately 125,000 kilometers, an integrated battery test revealed the pack retained roughly 92 percent of its original capacity. This aligns with observations from other used EV retailers, who have noted similar health percentages in LFP batteries after 100,000 kilometers of use.
