11 or 22 kW AC charging: what changes?
The number on the charging point is only one limit. Check the car’s onboard AC charger, the specific version and the power your installation can actually supply.
A car limited to 11 kW AC cannot accept 22 kW simply because the station offers it. A lower supply limit or incompatible phase arrangement can reduce the effective power further.
Optional onboard chargers can change the limit within the same model family.

01
Use the lowest compatible power limit
The examples below distinguish Togg T10X configurations with 11 and 22 kW AC and Fiat E-Doblò Passenger configurations with 7.4 and 11 kW AC. Their years and source markets are part of the specification, not evidence of current local availability.
02
Compare the same battery and charge window
For an illustrative 60 kWh usable battery, 20–80% stores 36 kWh. At 90% efficiency, 40 kWh must be supplied. With a compatible constant 11 kW, the estimate is about 3 hours 39 minutes, rounded up; at 22 kW it is about 1 hour 50 minutes.
The shorter result is only achievable when the car, point and supply all support that power. This table does not claim that an arbitrary 60 kWh car accepts 22 kW.
03
A home installation may impose another limit
Household contract capacity is shared with other appliances. A three-phase AC rating does not mean the same power is available from a single-phase connection. Follow the vehicle and charging-equipment specifications and have the installation assessed professionally.
Choose around the energy you need during your parking time. Paying for a higher rated wallbox does not necessarily shorten a session if the car or supply is already the limiting factor.
For public charging, compare time available, payment terms and any occupancy fee as well as the station rating.

Examples from the expanded catalogue
The Togg T10X V2 German 2026 configurations distinguish 11 and 22 kW onboard AC chargers. The Fiat E-Doblò Passenger Italian 2023 configurations distinguish 7.4 and 11 kW AC. A 22 kW point does not remove those version limits.
In a 30-minute AC illustration with 90% efficiency, 7.4, 11 and 22 kW store 3.33, 4.95 and 9.9 kWh respectively, if all power and battery-space conditions are met.
