FPrime has some rough edges, and it takes a bit to get used to, but the team's interest in continually improving the core for a wide range of users is the differentiator.
The most expensive tooling was the two floor jacks I purchased to make the process easier. The software needed was available from the manufacturer for a reasonable fee. The battery pack itself was surprisingly modular and simple to dismantle for repair.
I don't many things GM has done, but (at least back in 2010) they did a good job of letting owners do their own work.
Very beautiful paintings.
With an 11kW charger and assuming 12h in the garage, I can charge 132kWh in a day, which is far more energy than my battery can store. Thanks to this, when I park my car and decide whether to plug it in, all I need to think about is whether the car has enough charge now for my needs tomorrow. If it does, I leave it. If it doesn't, I plug it in.
With a 1.8kW charger, I'd only get 21.6kWh overnight. In my car, this is ~100km of range (~60mi) and about 30% of the battery. Now I either need to charge it every day (and add the hassle of unplugging/plugging every time I use the car) or I need to think about it more.
It's a matter of individual preference whether it's worth a few hundred dollars to avoid that friction but to me it's more than worth it for something that's part of my daily life.
I can't fathom not plugging my car in to charge when I park in my normal spot. It doesn't seem like much effort.
But my comment isn't to ridicule you - it's to point out how diverse and different our home charging experiences are, without awareness of others. I had no idea that anyone charged differently than I do.
Meanwhile, I have a motion-activated light switch in the garage. So I guess I don't want the hassle of flipping light switches, yet I plug/unplug daily.
Don't get me wrong, there are still issues here, like snow or back-to-back-to-back cloudy days. But the rate of a price change for solar has been pretty dramatic.
