Audi Q8 e-tron Home Charger Requirements by Trim
All 2 trims need the same thing at home: a 40A charger on a 50A circuit reaches full speed on every one.

Every Q8 e-tron trim, side by side
From each trim's onboard charger rating, not a generic EV number. Pick your trim to run the assessment with it pre-selected.
| Trim | Years | Onboard charger | Draw at 240V | Full-speed install | Empty to full | Range per hour | Range / battery | Check |
|---|---|---|---|---|---|---|---|---|
| 55 quattro | 2024–2025 | 9.6 kW | ~40A | 40A charger, 50A circuit | 11.9 hrs | ~23 mi | 272 mi / 114 kWh | Check panel |
| SQ8 quattro | 2024–2025 | 9.6 kW | ~40A | 40A charger, 50A circuit | 11.9 hrs | ~21 mi | 253 mi / 114 kWh | Check panel |
Draw = onboard charger kW x 1000 / 240V. Empty to full = battery kWh / charger kW. Range per hour = charger kW x the trim's efficiency. DC fast peaks: 55 quattro 170 kW, SQ8 quattro 170 kW.
Range added per hour, by charger size
Miles added per hour of charging at common home charger settings. Past a trim's onboard rating a bigger charger adds nothing, so those cells are marked.
| Charger | 55 quattro | SQ8 quattro |
|---|---|---|
| 16A (3.8 kW) | ~9 mi | ~9 mi |
| 24A (5.8 kW) | ~14 mi | ~13 mi |
| 32A (7.7 kW) | ~18 mi | ~17 mi |
| 40A (9.6 kW) | ~23 mi | ~21 mi |
| 48A (11.5 kW) | ~23 micapped by car | ~21 micapped by car |
| 8-hour overnight, full speed | ~184 mi | ~168 mi |
What this means for your panel
The circuit in the table is what lets your trim charge at its full rating. A smaller circuit still works and charges slower. Whether your panel has room for the circuit you want depends on everything else already on it: that is the actual assessment.
Connector: CCS. CCS (Combined Charging System) is the most common connector on non-Tesla EVs for both home Level 2 charging and public DC fast charging.
Audi Q8 e-tron charging questions
What size circuit does a Audi Q8 e-tron need for home charging?
Every Q8 e-tron trim reaches its full home charging speed with a 40A charger on a 50A circuit. Whether your panel has room for that circuit depends on everything else already on it.
How many amps does a Audi Q8 e-tron draw on Level 2?
40A at 240V, depending on trim. That is the onboard charger rating (9.6 kW) divided by 240 volts.
How long does a Audi Q8 e-tron take to charge at home?
About 11.9 hours from empty to full at each trim's maximum Level 2 speed: battery size divided by onboard charger rating. Most nights you only refill what you drove.
Do all Q8 e-tron trims charge at the same speed at home?
For 2025 models, yes: every Q8 e-tron trim listed here uses a 9.6 kW onboard charger, so the home install is the same.
