What the car needs
The A290 accepts up to 11 kW on AC. In a single-phase home, that normally means 7.4 kW; with three-phase, up to 11 kW. The usable battery is 52 kWh, so a 10–80 % charge takes about five hours at 7 kW and a little over three hours at 11 kW. From 0 to 100 %, allow around seven and a half hours at 7 kW.
Wallbox yes, emergency socket no
A normal domestic socket is not designed to charge a car for hours. For daily use, install a wallbox with protection and load management. In an apartment building, you will need the owners’ approval and a qualified installer.
Do not use extension leads, multi-socket adapters or cheap plugs. And do not schedule charging in two places at once: choose the car or the charger, not both.
The routine that works
- Set the schedule in the car’s app.
- Leave the charger unlocked and plug in one or two hours before the start, not the night before.
- Limit daily charging to 80 %. Go to 100 % only before a long trip.
- If you are leaving in the cold, precondition the cabin while still plugged in.
- Check real consumption every month; the app can lag.
When it will not charge
A red light at the charge port means charging has stopped. Check the schedule, unlock and relock the car, and check the charger app. Some owners have had to update charger firmware or change the scheduling mode.
If the car has been plugged in for hours without starting, it may have entered a deep sleep. It is not a battery fault; it is vehicle management. Try plugging in closer to the scheduled time.
Cost
On a 0.15 €/kWh overnight tariff, a full 52 kWh charge costs about €7.80. At 18 kWh/100 km, that is around €2.70/100 km. It is a reference, not a promise: prices and consumption change.
