I am still not sure why this is so much $$$$$$$$$?
I’ve no idea. But I know more than one person who’s paid roughly that for the charger and install.
L
Union electricians? State permitting/inspections?
I suppose you could install a battery storage pack to charge up and then use it for vehicle charging. Sort of distributing the load over a longer period of time.
All costing money, of course.
Here’s an article on the cost of installing a charger and an answer to the question on multiple car charging.

“To add a 220v circuit should not cost that much. A 40amp 220v curcuit would require 8/2 awg wire which is around $2/ft. The 40a breakers would be about $20/per( 2 needed ).”
P = V * I
A maxed out 220v circuit would provide 220 * 40 = 8,800 watts.
A 150Kwatt hr batteery would therefore requir 150,000 / 8,800 = 17 hours to charge.That’s not counting for line losses.
So you probably need two circuit breakers plus an AC to DC conditioned inverter.
Now add a second car for the wife, or two if you have a highs school kid.
Yup. EVs are free!!

Most home services don’t have the capacity for 40Amp draw chargers
If you home has a full 100Amp panel, you will need to upgrade the panel and service to 200Amp
That is why you are seeing 6 grand install charges
And in some jurisdictions you need to upgrade everything else to code, got Multiwire circuits? Knob and tube? non grounded romex or Bx? You need to rewire your entire house as well. Plenty of stories on electrical boards of people paying 20K to 30K to upgrade their house so they can plug in their new golf cart car
Its insane
It doesn’t cost that much...that’s ridiculous. I installed a 240v Tesla charger and the cost was maybe $400 for materials, total. Granted, I did the work myself, but in no way should it cost $6500.
I put in a 50amp circuit and a level 2 charger for a little over $1000 back in 2021. We have a plug-in hybrid which has a much smaller battery than a fully electric vehicle. It takes about 2 hours to charge fully, and I get 31 miles on electric before the gas engine takes over.
Since most of our in city appointments are completed within 31 miles, it’s easy to run errands, attend appointments, etc. and keep the battery charged between them if I have to return home.
The gas engine kicks in if we need it so there’s no range anxiety, and it doesn’t have to operating where it’s not as efficient — in slower stop-and-go city/suburban driving.
The company I bought my unit from (Grizzl-E) does sell a unit with two charging connectors. It will use up to the recommend amp rating of the circuit but will split the load if two vehicles are connected.
Personally I like the plug-in hybrid vehicles. You get the best of both worlds — electric for slower in town driving and gas for long trips. Plus charging time is much quicker due to the smaller batteries.
Too bad the industry isn’t moving in that direction as you could build 2-4 plug-in hybrids for the battery requirements of a single fully electric vehicle.
Doubt seriously that the breakers or $2 a foot wire will constitute the major part of the multi thousand dollar upgrade ... labor!!!!!!!!!!!!
I you have the most common 100Amp service then you will using 40% of your available power to charge your EV. That is only one RV. So if you have 2 charging circuits charging two cars at one time then it would 80%. So you basically have to go to a “Green Acres” style of power management for the rest of your home.
