@hallcp You are correct, my commute is 73 miles round trip and I only charge at home. I start each day at 100 and by the time I hit work (Capacity@work) I am usually in the 60s% remaining. After the drive home (Capacity@home) I usually clock in around 24ish%. What you don't see in the graphs is that I note ifI did any extra driving that day, e.g. grabbed some milk on the way home. Some of the days where I used significantly more charge than others are probably days I drove more than 73 miles.
@JeffRay One of the nice things about living in South Florida is that often our overnight lows are warmer than the midday highs in the rest of the country. It's nice that it takes much less energy to cool the cabin 10 degrees then it is to warm it up by 40 degrees. The other thing about Florida it is super flat, the only hills that we have in the state tend to be landfills. Some of the buildings in downtown Miami during a king tide are at once, below sea level and taller than the highest natural point in the state. As to your last point, I don't yet have a yearly battery review to look at. I've only had the car for 8 months or so. Before I bought the car, I brought it to a MB dealer for a pre-sales inspection and even though I asked several times if they can service/inspect a 250e, 5 minutes after I show up it was pretty clear they had no clue. However, they were able to tell me that my 12V battery was in excellent shape.
I wanted an EV commuter car and had a whole spreadsheet of possible ones that could support my commute, the 250e was perfect. I was a little worried at first because so many of the online forums said that the 250e was not the most efficient, only around 2.5 miles/kWhr. That would have been barely enough to get me through the day. The most generous said 3.0 m/kWhr; I was pretty stoked when I realized I was average 3.4 miles/kWhr, but as stated above, it's pretty much the most ideal of driving conditions.
