EV batteries last longer than drivers feared
Study suggests used vehicles can retain about 90% of original usable battery capacity after 150,000 km.
TL;DR
- Most used EVs retain about 90% of original usable battery capacity after 150,000 km, according to an Aviloo study.
- EV battery warranties typically cover 8 years or 100,000 miles, requiring replacement if capacity drops below 70%.
- The study found median battery health for 20 popular EV models was between 87% and 94% after 150,000 km.
- Battery degradation speed varies significantly based on climate, battery size, and driver habits, such as parking charge levels.
- Experts recommend not parking EVs at 100%, 90%, or 80% charge, suggesting 30% to 70% as ideal.
- There are calls for mandatory battery health certifications to increase consumer confidence in the used EV market.
