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.
Germany, 3-phase, 400V to the home is pretty much the standard here.
Yeah, yeah, I know. It was frustrating in the beginning of electric cars - all the manufacturers put those single phase chargers into their cars because US and Asia just didn't need anything else and we were left bumbling along at 4.2kW charging to avoid too much asymmetric load (most providers here limit you to 20A asymmetry although I've been known not to give a fuck) while two wonderfully capable phases sat around doing nothing and the third was only used half the way at most.
Yeah, that looks interesting, although it's unusual to see any "intelligence" delegated to the panel housing. Usually here, the panel cabinet is something like this:

...which is a mechanical housing and some very basic distribution on the lower left. Everything else is built while the distributor is fitted. Look like this in the end:

Anyway, you can get this functionality right now, for example with a go-e wallbox and the go-e controller and retrofit it without touching the rest. That's not really a reason not to get an electric car.
