Your cabin trips should be quite easy for an Etron. One way. Note that if you have only L1 110 v charging at the cabin it could easily it 3 days! For the charge to fill back to 100% to get you home. An L2 240v Charge should get you full with an 12 hour overnight charge.
Thanks Theo1000 for the answer. And yes, I was planning on getting a 240v charge for the cottage. A couple of follow up questions -- just to be clear, with the E-Tron, even if you still go to a 100% charge, there is still a built-in buffer of 12%? I wonder why with this built-in buffer they still only recommend a 80% daily charge?? And when you say based on your experience with EVs you feel comfortable doing this -- you don't think overcharging to 100% maybe 20 or so times a year would have a material impact on the battery life over time? Thanks again!

In my opinion (and a lot of the internet) 204 is too low. It is a personal choice that is based on driving requirements. For 99% of my driving 204 is fine. Road trips and camping could pose a problem. That said I probably will be trading in my Q7 tomorrow or Saturday.

I'd reconsider a daily 100% charge. This will significantly degrade your battery faster. This isn't necessarily a 12% capacity buffer at the top end of the charge voltage. It could be split 6% bottom/6% top. If you're daily charging to above 4.0V per cell, it will degrade your battery faster.

Also, unless you have daily long range needs, 80% daily charge should be plenty of in-town range.

Yes that is correct. The 12% buffer is over and above the 100% manufacturer rated charge. The battery will never get to physical 100% charge. Ever. On a 95 kwh battery we will get ~ 84.5 kwh at 100% charge. There is a 10 kwh permanent buffer in there. The speculation in this forum is that this is done to ensure a consistent charging experience. The etron charges at 50 kw @ 100%. Most/All other EV's do not. The last 5-10 kwh is less useful than people realize on long distance trips due to very slow charge rates. You can fast charge at almost full rate to 100% and then go. Good Engineering.

My experience is that you can L2 charge to 100% 365 times a year and you won't have any issues. It is very slow compared to what the batteries are designed for @ L3 Fast charge. Both my EV's often charge to 100% 2-3 times in a day and I have seen minimal degradation. Both my EV's are liquid cooled as the Etron is, so again I don't expect any large degradation. The technology is so simple and stable that manufacturers can control battery conditions very accurately.

My airport for my business travel is 60 miles away. So... charge, drive, park, return, charge... and I am good. The dealer is 70 miles way. Still good.

But, my daughter might be moving to a college 234 miles away. I'd do this 1-6 times per year, and can handle a coffee stop.

So... it is within the range of 98% of my trips I have taken in the past 5 years I'll be fine.

That all said, I am waiting for the e-tron Sportback. Maybe they will have squeezed out more range by then. Or, maybe it will be zippier, and have less range. If the e-tron SB is less than 200 miles, that would be a death sentance.

I think this will affect the take-up rate. I expect a few reserved cars to be left with the dealer, particularly if the report of a lease residual of less than 50% is true. This range will have an effect on resale prices, much like the BMW i3 resale value hammered those unfortunates that purchased rather than leased. When BMW began to really incentivize the i3 leases, sales picked up, but were never "brisk". I think the combination of a mid-$50's price combined with a 70 ish mile range was deadly. This could be true for e-Tron also. $80's price and lowest range of the competition. If the dealers end up with 4 or 5 e-Trons on the floor, discounting/incentives will start. I don't think I want to be another early adopter. I think there will be plenty of e-Trons available middle of next year.

A stated 204 mile, is usually 10-20% lower in real world driving, therefore making the stated range even more dismal. I was hoping that things would be better, even though the asthetics and finishes of the Audi are superior, it's akin to introducing a Galaxy 8 with a new casing, when the tech has already moved to the 10 model.

At the price point and range numbers, a lot of people are going to be put off, especially when considering like-models. Personally I really like the new Polestar 2 and am looking forward to seeing what it can offer.

Wow that's just...embarrassing. From a 95kWh battery? No amount of fast-charging is going to make this more than a city car, not suitable for road trips of longer than 120-150 miles. Someone said it best, "range anxiety is not luxurious".
