You can’t charge at Level 2 with more current than the vehicle requests. Both Tesla and ID.4 can pull 48 amps from the circuit and not any higher regardless of what the charger is capable of.An 80 Amp circuit is very large for a home. Most homes have 200 Amps total coming into the house. Older homes less. Unless you routinely need to charge in a time that is less than overnight a 50A circuit absolutely fine. And, remember the faster you charge the harder it is on the battery, so fast charging at home really buys you nearly nothing.
My electrician had told me that I have a 250 amp service to the house with less than 150 being used, so I think I can swing a 100 amp circuit to the charger. I don't know the price, but also if I have it installed before the end of 2021, I will get 30% off the installation price as a tax credit. I don't think anyone knows if this credit will be extended in 2022.That's going to be one heck of a quote! Most USA folks now have 200A service, but many still at 100A and your quote would be for a circuit handling half or all of that. So in addition to heavier EVSE-feed wire gauge and breakers likely heavier grid-entry wire and larger capacity entry panel, bordering on commercial application!!
Related: most of the homes in my 3-year old retiree-downsized development have 100A service. When I roughed-in for a 48/40A EVSE during construction that alone drove me to an interior 200A panel. Thankfully the line off the transformer to my current NEC exterior disconnect was already sufficiently robust.
