I don't understand the fear of not having a full battery. Even if you continuously drain the battery 10% a day because you can't charge fast enough, the by the of the week you'll have 30-40%. Is it that difficult or impractical to visit a supercharger once a week?
If you have a L2 charger and you plug it in every time you park at home, how much more convenient is it really vs using L1 that you also plug in everyday?
The thing is, if you even have 1 day a week where you can plug the car in for 16 hours, you're gonna keep the battery topped up anyway and you won't even need to make a supercharger stop at all.
Yes, depending on your situation, the difference between L1 and L2 is significant and worth paying for.
Another way to state the figures in your example, if you’re “net daily SOC loss” is 10% (which sounds reasonable for the OP’s commute) you only have a 30-40% buffer for the entire week. It doesn’t take much (cold weather, unexpected errands, bad traffic) to eat through a significant portion (or all) of that 30-40% before you get to the weekend.
This happened to me twice in two months of L1 charging. It’s personal preference of course but I didn’t like getting home Friday evening knowing that I’d either have to go out of my way to a super charger (closest is 20 minutes away) or spend half my weekend on the plug. It’s either don’t use the car for 20 hours or waste over an hour of my time in a part of town I don’t really go to.
Now, granted, this didn’t happen often. But as I said before, it’s always on your mind as a possibility and you’re constantly concerned with avoiding it. I never think about this with L2 because I know no matter what SOC I return home with in the evening, I’m getting back to 75-90% by the time I wake up.
