Since you've studied EV charging and I haven't, the I'm curious what the actual cost is to fully charge the battery? I'm talking about the utility company rate for that amount of electrical consumption at your home when you fully recharge the car.
The (higher) summer residential rate here in Kansas City is $0.13511/kWh. I have a 30A, 240V charger, but my Volt can only charge at 3.3kWh, which works out to about 16A. It could be up to $2.03 for a full charge. In the off peak season, the rate is as low as $0.08/kWh, or $1.20 for a full charge.
On a 60kWh car (Leaf, Bolt, base Tesla Model 3) a full charge would cost $4.80 - $8.10 and could take you 220-260 miles. Worst case would be about $0.037 pretty mile for "fuel". Regular is $3.05 at the station down the street, and in a 40mpg car you're looking at $0.076 per mile for gas.
Your local rate and utility incentives may change the cost dramatically.
Yes, if you want to pony up for a new car; for some of us, that is not an option.
DC fast chargers are not an at-home installation, and there are none within several miles of home.
Without a garage, any charger can be a problem, in a place where it rains regularly (unlike California).
And, I haven't seen any mileage comparison done in freezing weather, where electric vehicles would be at a distinct disadvantage.
I'm not one to buy a new car either, my Volt was a 2 year old lease return when I needed a new to me daily driver. When it's time to find a different daily driver a used car will be what I go for next time as well.
When I bought the Volt I was driving 60 miles round trip per day when I went to the nearby office, and 140 if to the far site. I have access to chargers at home and work. My short commutes were 100% electric, and 2/3 electric on the long trips.
I can see a drop from 40 EV miles down to about 32 miles on the coldest winter days, but preheating/remote starting while plugged in helps keep the range up.
As far as chargers go, you're right that DC fast chargers are non-residential. Very few people have 480V 3 phase service. My local utility worked with ChargePoint to roll out 2,000 chargers (2-6 power site) a few years back. Electrify America, EVGO, Tesla, Greenlots (aka Shell gas stations) and others are rolling out charging stations across the country. The company I work for supplies compact outdoor power distribution systems to all the companies above. If you don't have one nearby yet, you likely will in the next 1-4 years.
A 30A (7.2kWh) J1772 SAE charger is pretty normal, and could recharge many EV models from empty to full overnight. J1772 and the combined DC version have ground fault protection and are designed for safe outdoor use, even in wet weather. Controlled access solutions exist to keep random people from using your power for their car.
