Audi Q4 e-tron Charging Time
A 2026 Audi Q4 e-tron takes about 9.5 hours to charge from empty to full on a 240-volt Level 2 charger, according to its EPA test, and 9.5 to 12 hours across the 2026 trims. On a standard 120-volt outlet it takes about 60 hours. A full charge puts about 86.9 kWh through the plug for 251 miles of range.
Audi Q4 e-tron charging time by charger
Figures for the 2026 Q4 55 e-tron quattro. 20% to 80% is a typical daily top-up; 0% to 100% is a full charge from empty.
| Charger | Power | 20% to 80% | 0% to 100% |
|---|---|---|---|
| Level 1, 120 V outlet (12 A) | 1.4 kW | 36 hr 13 min | 2.5 days |
| Level 2, 240 V, 16 A | 3.8 kW | 13 hr 35 min | 22 hr 38 min |
| Level 2, 240 V, 24 A | 5.8 kW | 9 hr 3 min | 15 hr 5 min |
| Level 2, 240 V, 32 A | 7.7 kW | 6 hr 47 min | 11 hr 19 min |
| Level 2, 240 V, 40 A | 9.6 kW | 5 hr 26 min* | 9 hr 3 min* |
| Level 2, 240 V, 48 A | 11.5 kW | 4 hr 32 min* | 7 hr 33 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 9.1 kW; if that is its limit, a faster wall charger won't shorten the 9.5-hour full charge.

Cost to charge a Audi Q4 e-tron
A full charge from empty draws about 86.9 kWh from the wall. At 18 cents per kWh it costs about $15.64, and a 20% to 80% top-up about $9.39. The EPA rates the Q4 55 e-tron quattro at 34.6 kWh per 100 miles, which works out to 6.2 cents a mile. The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
Audi Q4 e-tron fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check Audi's quoted figure for the Q4 e-tron. The EV charging curve guide explains why it slows.
