Charging times for the Audi Q8 e-tron 55 by charger type. 10 to 80% is the standard comparison because rapid charging slows sharply above 80%.
Charging the Audi Q8 e-tron 55 at home
A 7kW home wallbox is the workhorse. From 10% to 80% takes about 11h 47m, and a full charge from empty about 16h 50m, which fits comfortably overnight. On a cheap overnight tariff window, that is also the cheapest way to run the car by a distance.
A standard 3-pin socket manages around 2.3kW. A full charge that way takes roughly 51h 12m, so treat it as a backup rather than a routine.
The car's on-board AC charger takes up to 11kW, so on a 22kW public AC post it still charges at 11kW: about 7h 30m for 10 to 80%.
Rapid charging on trips
On a 50kW rapid charger, 10 to 80% takes about 2h 6m. On a rapid charger that can match the car's 170kW peak, that drops to about 46 minutes.
These are real-world estimates, not brochure figures: cars only hold their peak rate for part of the session, and the rate tapers steeply above 80% to protect the battery. That is why topping up to 80% and driving on beats waiting for 100% on every trip.
Cold batteries charge slower. In winter, expect the first rapid stop of the day to run behind these times until the pack warms up.
