| Mobile Charger (2.3 kW) | 230V / 1x10A | 2.3 kW | approx. 39 hrs 30 mins |
| Single-phase 16A (3.7 kW) | 230V / 1x16A | 3.7 kW | approx. 24 hrs 30 mins |
| Single-phase 25A (5.8 kW) | 230V / 1x25A | 5.8 kW | approx. 15 hrs 45 mins |
| Single-phase 32A (7.4 kW) | 230V / 1x32A | 7.4 kW | approx. 12 hrs 15 mins |
| Three-phase 16A (11 kW) | 230V / 3x16A | 11 kW | approx. 8 hrs 15 mins |
| Three-phase 25A (17 kW) | 230V / 3x25A | 11 kW* | approx. 8 hrs 15 mins |
| Three-phase 32A (22 kW) | 230V / 3x32A | 11 kW* | approx. 8 hrs 15 mins |
* Limited by the car’s onboard charger
Choosing a Charging Station
The Audi Q4 e-tron 40 comes with an onboard charger capable of up to 11 kW. This means it’s recommended to use a charging station with this power output, especially if you have three-phase power at home. Charging stations with higher power won’t increase charging speed, but they won’t cause any harm either.
Electrical Installation Considerations
The Audi Q4 e-tron 40 can only utilize the maximum 11 kW when connected to a three-phase electrical connection with minimum 3 x 16A. If you don’t have this yet, you can temporarily connect the charger to a single phase. In this case, the maximum power will be limited to 3.7 kW.
Mobile Charging Devices
Mobile charging devices (portable) are a practical backup solution, especially if you don’t have a fixed charging station. Charging through a standard outlet is possible but takes significantly more time. Therefore, they are recommended mainly for emergency situations.
