A new study conducted by Swedish used electric vehicle retailer Carla indicates that modern EV batteries are proving more resilient than many skeptics anticipated. The analysis, which is based on nearly 100,000 individual battery health tests, suggests that electric cars retain the vast majority of their capacity even after significant usage.
The Leaders in Battery Health
Among the vehicles analyzed, the Kia e-Niro emerged as a top performer, leading the health rankings after high-mileage use. The data highlights that while all batteries experience some degradation, the rate is often much slower than previously feared for modern lithium-ion systems.
Factors Influencing Longevity
The study also sheds light on the variables that impact long-term performance. Researchers noted distinct differences based on specific vehicle models, battery chemistries, and the manufacturers supplying the cells. These findings suggest that engineering choices and thermal management systems play a critical role in how well an EV holds its value and range over several years of ownership.
