Audi Q4 e-tron 45 charging cost & time
| Scenario | Energy | Time | Cost |
|---|---|---|---|
| Public DC 20% → 80% | 46.2 kWh | 19 minutes | $27.72 |
| Public DC 0% → 100% | 77 kWh | 48 minutes | $46.20 |
| At home (AC) 20% → 80% | 46.2 kWh | 4 hours 12 minutes | $15.25 |
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% | 22 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%) models the charging curve tapering as the battery fills, so it is more realistic than a flat estimate. Real DC times still vary with temperature, battery state, and the charger.
Charging speed
The Audi Q4 e-tron 45 is estimated to charge from 20% to 80% on public DC fast charging in about 19 minutes (ultra-fast DC).
Estimated. Real DC charging slows as the battery fills, so the time varies by model, temperature, and charger.

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 267 km of range for $27.72. Driving the same distance on petrol would cost:
| Engine size | Petrol cost | You save |
|---|---|---|
| ≤ 1000 cc | $28.66 | $0.94 |
| 1000–1500 cc | $33.87 | $6.15 |
| 1500–2000 cc | $41.69 | $13.97 |
| 2000–2500 cc | $49.51 | $21.79 |
| > 2500 cc | $59.93 | $32.21 |
Estimated from typical combined fuel use by engine size and Regular unleaded (ULP 91) at $1.95/L. Charging at home saves the most; actual figures vary with driving and conditions.
