AVILOO Launches World's Largest Independent EV Battery Study
Aviloo’s analysis of 500,000 battery tests found all 20 models kept at least 90% median health, with the Hyundai Ioniq 5 leading the study.
- Austria-Based Aviloo published a study of 500,000 EV battery health tests across 20 popular models, revealing that most batteries retain over 90% capacity after 100,000 miles.
- Compiled from 2022 to 2026, the report aggregates data from North America, South America, Europe, Asia, and Australia using the independent Aviloo FLASH Test rather than relying on dashboard-reported figures.
- Hyundai Ioniq models demonstrated the highest capacity retention, while air-cooled vehicles like the Renault Zoe and Nissan Leaf experienced faster degradation, often influenced by hotter climates and frequent fast charging.
- State of Health can vary by up to 13.5% between identical vehicles, said Marcus Berger, CEO of Aviloo: "You simply can't know where your car sits in that range without testing it independently."
- While concerns persist that EV batteries will fail prematurely, the data confirms they remain viable long-term, prompting Aviloo to launch a new Battery Warranty across Europe with financially backed health guarantees.
