I can only give you my experience for one half your question.Unfortunately, with the amount of driving I do, I actually need to charge away from home more frequently than almost anyone else. These are not road trips per se. 90% of my driving is for work and even 360 (realistically) miles of range means that I have to charge away from home at least once a week. I often will do it a little more often than once a week for convenience and sanity so I am not constantly calculating my efficiency and driving 68 MPH to guarantee I'll have enough juice to get home at night. But, your point is well taken. I charge at home as much as possible even though it frequently means charging to 100% the night before a long day.
As I'm typing that, I just started to wonder about something. They say don't charge to 100% unless necessary. They (yes, those same people) also say don't DCFC more than necessary. Does anyone actually know which one of those two evils is the lesser? Hmmm....![]()
I've had my AGT for 15 months now and I have exclusively used DCFC as I do not have access to anything else. 99.5% of that has been on EA (150/350) chargers. I almost always charge to 80-85% other than road trips when I'll occasionally go to 90-95%. I charge, on average, non-road trip wise, every 1-2 weeks.
My max range hasn't dropped more than about 2 miles, maybe less. (Knock on wood)
