Electric vehicle battery degradation and durability

Overview

Recent research and real-world testing indicate that electric vehicle (EV) batteries are more robust than previously assumed. Research from Stanford University suggests that using “dynamic cycles”—simulating real-world driving with varying charging and resting phases—may 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% until well after the 200,000-kilometer mark. Expanding on previous findings, new data indicates that while battery capacity often sees its most significant drop during the first 150,000 kilometers, the rate of decline tends to stabilize and become more gradual over time. Furthermore, vehicles with smaller batteries may experience less degradation because they undergo fewer charge cycles compared to larger batteries. A large-scale study by Austrian diagnostics company Aviloo, which analyzed 500,000 battery tests conducted globally between 2022 and 2026, provides further empirical evidence. The study found that batteries retain approximately 95% of their capacity after 50,000 kilometers and roughly 91% after 150,000 kilometers. Real-world observations support these trends; for instance, a test by the Dutch magazine AutoWeek on a high-mileage Volkswagen Passat GTE revealed the battery retained over 76% of its original usable capacity after 300,000 kilometers. New research commissioned by the British Vehicle Rental and Leasing Association (BVRLA) and conducted by New AutoMotive, analyzing 47.4 million MOT inspection records in the United Kingdom, suggests high-mileage EVs may be more durable than petrol models. While failure rates are similar at low mileages, EVs show a stabilizing failure rate of approximately 16% after 60,000 miles, whereas petrol vehicle failure rates continue to rise. For vehicles between 90,000 and 120,000 miles, EVs had a failure rate of approximately 16.5%, compared to 22.1% for petrol cars.
