EV details
Is it enough for your day-to-day?
One charge lasts 1 day in winter (−10 °C) and 2 days in mild weather.
Using real-world range, charged to 80 %, 10 % reserve: 83 km per charge in mild weather, 66 km in winter.
Mild means ≈ 23 °C, cold ≈ −10 °C without pre-heating — the same for every car, so the figures compare.
What does charging cost?
| €/kWh | Full charge | per 100 km | |
|---|---|---|---|
| Home (wallbox) | €0.34 | €6 | €7.24 |
| Public AC | €0.50 | €9 | €10.65 |
| DC fast charging | €0.60 | €11 | €12.79 |
Prices from the open assumptions (adjustable in the calculator); consumption = mild real-world incl. charging losses.
NMC: high energy density (more range), usually charge to ~80% for longevity.
