GoKawiilAviloo study: EV batteries retain ~90% capacity after 150,000km
A study by Austrian battery-analysis firm Aviloo, based on over 500,000 tests across 20 popular EV models including Tesla's Model Y and Volkswagen's ID.4, found median battery health ranging from 87 to 94 percent after 150,000 kilometers of use. The research found degradation levels between 91-97 percent at 50,000km and 88-95 percent at 100,000km, though rates varied widely depending on climate, battery size and driving habits.
GoKawiil's interpretation of the reporting above, not reported fact.
Battery longevity fears have been a major barrier to EV adoption, and this data suggests those concerns may be overstated relative to manufacturer warranty thresholds of 70 percent capacity. The findings also highlight that, unlike combustion vehicles, an EV's true condition can't be judged by age or mileage alone, complicating used-EV valuations and buyer confidence.
- Median EV battery health stays around 87-94% even after 150,000km of driving
- Degradation varies significantly based on climate, battery size and usage patterns, not just mileage
- Study excluded Chinese EV models due to insufficient data, limiting global applicability
