Isn't 100A considered inside for an all electric home?
Most homes nowadays are 200A. I could probably make it work, or get a smart panel to not have to worry about it...but upgrading service is practically impossible unless I can get someone else to pay for it. We'd have to remove a bunch of trees to trench to where the junction box is, and then trench across our driveway, too. Unless I lucked out and there oversized conduit there already, but I highly doubt it. As much as I've been told, the neighborhood was built with direct-bury service entrances.
16amp 240 is quite acceptable for overnight charging
That makes sense...if the charger is aware of its own load and the load of the whole house, it can slow down or stop charging to let the other stuff catch up.
I don't know where you are but 3-Phase is rather uncommon in US Residential. We use split-phase, where we have two 120v lines that use a common neutral, and we get 240v across the two 120v hots (with no neutral...but some 240V outlets do have a neutral leg for parts of the appliance needing 120V.
A while ago, the YouTuber Technology Connections did a segment on the Span smart panel...and I think there's a handful of others...that measures the load of each circuit and can triage circuits if there's too much demand. This is really where smart appliances should be heading. It's cool that my dryer can tell me how many KWh are consumed by a load, but I'd much rather it be able to cooperate with all my other loads and maybe turn off the heating element for a bit.
