Summary
A recent study by the diagnostic firm Aviloo analyzed data from 500,000 electric vehicle tests conducted globally between 2022 and 2026. The findings reveal that most EV batteries maintain high performance levels even after high mileage, debunking fears of rapid degradation. Top-performing models like the Hyundai Ioniq 5 and Mercedes-Benz EQA retained over 93% of their original capacity after 150,000 kilometers. In contrast, smaller vehicles with air-cooled batteries , such as the Nissan Leaf and Renault Zoe, experienced faster wear due to more frequent charging cycles. While the general outlook for battery longevity is highly positive , factors like extreme climates and charging habits can cause significant variations in individual health scores. Overall, the research confirms that modern electric cars typically lose only about 10% of their range after several years of heavy use.
