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.

Audi Q4 e-tron 45 charging time by charger power

Standard outlet2.2 kW0% → 100%35 hours
Home wallbox7 kW0% → 100%11 hours
Public AC11 kW0% → 100%7 hours
DC fast175 kW10% → 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 sizePetrol costYou 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.
