EV batteries last longer than drivers feared
Summary
A recent study shows that electric vehicle (EV) batteries last longer than many drivers expected, with most retaining about 90% of their original battery capacity after driving 150,000 kilometers. The study also found that battery wear varies based on climate, battery size, and how drivers charge and park their cars.Key Facts
- Most EV batteries keep around 90% of their original charge capacity after 150,000 km.

- The study tested over 500,000 batteries from 20 popular EV models worldwide between 2022 and 2026.
- Battery degradation varies by climate, with hotter areas causing faster wear.
- Charging habits affect battery health; parking with a battery charge between 30% and 70% is best.
