Study of 500,000 EV batteries shows some models age better than others

Aviloo, an EV battery diagnostics company, analyzed half a million battery health tests across 20 popular electric vehicle models from 2022 to 2026. The Hyundai Ioniq 5 led with over 97% capacity remaining after 50,000 km and maintained over 95% at 100,000 km. Tesla Model Y and Model 3 performed mid-range, with around 90% capacity remaining after 150,000 km. Smaller battery models like the Renault Zoe and Nissan Leaf showed higher degradation, dropping below 88% at 150,000 km. Overall, most EVs retained at least 90% capacity after nearly 100,000 miles.

• Hyundai Ioniq 5 retained >97% capacity after 50,000 km
