Audi Q4 e-tron 45 charging time by charger power
How long the Audi Q4 e-tron 45 takes to charge at different charger power levels, capped by its own onboard limits.
| Charger | Power | Charge | Time |
|---|---|---|---|
| Standard outlet | 2.2 kW | 0% → 100% | 35 hours |
| Home wallbox | 7 kW | 0% → 100% | 11 hours |
| Public AC | 11 kW | 0% → 100% | 7 hours |
| DC fast | 175 kW | 10% → 80% | 28 minutes |
AC rows assume constant charging power and a 0% to 100% charge. Real times vary with the onboard charger, temperature, and the charger you use.
The DC fast row (10% to 80%) is anchored to a measured charging time for this model, so it reflects the real charging curve. Times still vary with temperature and conditions.
Charging speed
Based on measured data, the Audi Q4 e-tron 45 charges 10% → 80% on DC fast charging in about 28 minutes, peaking at around 175 kW. Avg ~120 kW 10-80% (400V); EV-DB Q4 45 MY24-26 (77 kWh usable, matched).
The Audi Q4 e-tron 45 is estimated to charge from 20% to 80% on public DC fast charging in about 25 minutes (ultra-fast DC).

Battery care
This car uses an NMC battery. For daily use, charging to about 80% and topping up to 100% only before long trips helps it last longer; heat is the main thing that ages it.
Savings vs a petrol car
This charge adds about 173 mi of range for $22.18. Driving the same distance on petrol would cost:
| Engine size | Petrol cost | You save |
|---|---|---|
| ≤ 1000 cc | $18.00 | -$4.18 |
| 1000–1500 cc | $21.27 | -$0.90 |
| 1500–2000 cc | $26.18 | $4.00 |
| 2000–2500 cc | $31.09 | $8.91 |
| > 2500 cc | $37.63 | $15.46 |
Estimated from typical combined fuel use by engine size and Regular gasoline at $4.46/gal. Charging at home saves the most; actual figures vary with driving and conditions.
