I’ve installed a couple of these charger units in rich peoples houses. The general rule is the more amps you can throw at it the faster it will charge the battery. That means a 100amp sub panel dedicated to the charger. Residential service is at max 200amp and that’s for larger homes. Most are 100 or 60. The meter will spin like CD player when charger is on. Most people who buy these won’t bat an eye when I charge them 2000+$ to install a dedicated sub panel. So for me, I say bring em on I need a new snowmobile.

An electric one?
I like the way you think.
A 200 amp service at 240v is fine.
Math says that’s 48 kw. Car won’t hold more than 96 kw at the current. 3 hour full charge uses about 70% of that supply.
What a lot of people don’t understand is the charger is in the car not the Level 1-3 units either in the home or available to the public. Those units are EVSE and just supply juice to the car.
The car determines the rate of charge and most, except Tesla, are limited to around 40-50 amps for a Level 2 or 150 amps for a Level-3.
EV’s are good for city areas where the commute is short and the driving distance is less than 20-miles. For driving long distances, the ICE is more efficient.
The plug-in hybrids were an attempt to bridge that gap, but the range on electric is very limited.
BMW offers the I3 REX which has a 650cc scooter engine that drives a generator that theoretically can drive as long as you can fill the gas tank (ave gas range 70 miles). But thanks to California regulations, the tank is limited to 1.7 liters, even though the tank holds 2.3 liters.
For the average American, until we return to living in densely-packed urban centers with short commutes, EV’s will never replace the ICE as a viable alternative.
Fast charging will generally shorten battery life. If something goes wrong & the battery catches fire, good luck trying to put it out.
Sorry, not too smart electrician.
Almost all homes today are 200amp service, many (like mine) have 400 amp service. Many homes over $400k will have 400 amp service.
60 amp service homes are ancient, maybe 1 out of 1,000. Even 100 amp homes are rare, maybe 1 out of 500.
No one who can afford an EV will have a house with less than 200 amp.
Still, 50 - 60 amp charging system is max on a single phase 240v service. High speed charging takes 480v/3 phase service, almost never found in homes - even of the ultra-rich - because it is not available in residential areas. Only commercial/industrial.
Problem is utility distribution system. Expert utility folk say system will collapse when 5% of all vehicles are EV’s.
Only answer will be rolling black-outs, as both Cal and Texas have experienced.
Then, you’ll be so happy with your EV when you don’t have electricity to power it.
The transformer feeding my has 12.5 KVA stenciled on it but I supposedly have 200 amp “service”. I smell BS....
