If you offered a 33 kWh usable battery, 10 hours. Except that for most folks out there would not be driving significantly more miles on a daily basis than they are now. Most folks don't completely drain their existing battery on a daily basis, just on the occasional longer trip.
A bigger battery means 2 things for most current owners. First you can go on longer occasional trips, such as out to the cost for me where I cannot make it easily now. Second it means that 5-10 years out there will still be enough range left to do local trips more easily.
Paradoxically a small battery needs a faster charger than a big battery since you are in more need to frequent top-ups to finish trips, while a big battery has extra reserve to get you home where the car is likely to have a good 10-12 hours to sit on the charger. A battery needs to be sized for your longest trip days, while a charger needs to support your average mileage. A fair number of people get by on level 1 charging at home already.
