The basis for this are extensive telemetry analyses by the fleet analysis specialist Geotab as well as accompanying jou…

Geotab screened the data from 22,700 electric vehicles from 21 different brands in 2025. With an average annual degradation of battery capacity, the batteries will probably survive the chassis of the car. However, the study notes a worrying increase in this wear compared to 2024, directly correlated with the intensive use of ultra-fast charging terminals. The battery is more enduring than the car itself Since the advent of the electric, an urban…

This is almost always unnecessary, according to a comprehensive data analysis.
