I believe that most of us overestimate the dangers of having the car sit for a while with a high charge level. I'd even go further to predict that by the time our batteries degrade significantly, cars will have such improvements (range > 1,000 miles??) that we'll want a new car anyway.
Having said that, I now get a warm fuzzy feeling car because now that I've changed to departure time scheduling, the car sits at a lower SOC most of the night.
My off-peak time is midnight to 3 PM, and I used to set scheduled charging for 12:15 AM. Now, I set scheduled departure for 7:30 AM and have end of the off-peak time set around then also. Since I charge at 24 MPH and to 250 miles, the only problem would occur if the car had less than 70 miles in the tank when I plugged it in. That is, it would have to charge for more than 7.5 hours and therefore do some charging before midnight. We rarely get it down so low, and I'm figuring that if so, I'll remember to adjust things so that it doesn't start charging before midnight.
I haven't had any issues with the car charging as soon as I plug it in.
So: I'm a convert.
