The Biden administration is poised to unveil new tariffs on imported Chinese electric vehicles, creating a potential roadblock for Chinese automakers wanting to expand into the American market.
Dunno. I’ve got 3 phase, 400V, 100A service which results in 68kW useable. However, because one of sub junction boxes which, unfortunately the wall boxes are connected to is wired internally with 10mm², I’ve enabled peer to peer load management across my wallboxes for now so they never pull more than 28A per phase. Most cars here support three phase charging so that’s still fine even for two cars. I’ll get to rewiring that, for now it works.
The go-e wallboxes I have support a central controller which in turn can measure current on all three phases into the home, e.g. to use a solar system to its maximum, but also to limit absolute load on the house connection. They just use three hall sensors for power measurement as far as I know, so installation is relatively unintrusive.
I went without that and solved the whole solar optimization using EVCC and regarding absolute load I’m just yoloing it, but then again, I do have a neat safety margin.
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.
