|---|---|---|---|
| Level 1, 120 V outlet (12 A) | 1.4 kW | 2 days | 3.3 days |
| Level 2, 240 V, 16 A | 3.8 kW | 18 hr 5 min | 30 hr 8 min |
| Level 2, 240 V, 24 A | 5.8 kW | 12 hr 3 min | 20 hr 5 min |
| Level 2, 240 V, 32 A | 7.7 kW | 9 hr 2 min* | 15 hr 4 min* |
| Level 2, 240 V, 40 A | 9.6 kW | 7 hr 14 min* | 12 hr 3 min* |
| Level 2, 240 V, 48 A | 11.5 kW | 6 hr 2 min* | 10 hr 3 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 7.2 kW; if that is its limit, a faster wall charger won't shorten the 16-hour full charge.

Audi Q8 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 Q8 e-tron. The EV charging curve guide explains why it slows.
