EV Charging Data
We Logged 341 EV Charging Sessions. 4 in 10 Had Problems.
This is not a survey. 72 drivers logged 341 public charging sessions in the EVcourse app between February and March 2026, rating each one good, okay, or bad. 39% of sessions had some kind of problem.
Short answer: Out of 341 logged public charging sessions, 39% had problems. Slow charging (20%), broken chargers (17.8%), and payment failures (13%) were the top three issues. Most of these are solvable with the right preparation.
How Did It Go?
Most of these are solvable problems. Slow charging often has a simple explanation. Payment issues get easier once you know the system.

About the Data
We know this is a small sample. 341 sessions, 72 drivers, three countries. Organizations like Transport & Environment and the EU Alternative Fuels Observatory track European charging infrastructure at a much larger scale. We are not pretending this is a definitive study of European EV charging. But it is real data from real sessions. We simply ask drivers: how was your latest charging session? As more drivers use the app, this dataset will grow. We plan to update these numbers regularly.
You can also log charging sessions together with your team or partner in the EVcourse app. See what problems come up most, and whether they keep happening.
This report presents anonymized, aggregated data from EVcourse app users who voluntarily logged charging sessions between February and March 2026. No charging networks, companies, or individuals are identified. Data reflects user-reported experiences and may not be representative of all EV drivers. EVcourse is not affiliated with any charging network operator.
