DC fast charging standards

I don't think Aus got that, nor us in NZ. Not it it wouldn't be useful as most, if not all public AC EVSEs do supply 3-ph.

If you did have a 3-ph domestic supply in a North American dwelling I think that would mean 208 V ph-ph instead of the healthy 240 you're already getting across the split single-phase supply. I'm sure someone will correct me if I'm wrong...

Our local power in NZ (and I'm sure Aus and many other countries) is 400 V ph-ph so 230 ph-N for domestic use.

 

The older konas wouldn't get any faster anyways since they have the 7.4kW max, so 3-phase wouldn't make any difference. Are they putting 3-phase in the cars in all markets now?

 

I have never heard of a standalone residence with 3phase. Apartment buildings and such definitely would have a 3-phase feed coming in from the street. But I can't see automakers switching to type 2 mennekes connectors just to support this case, since every other level 2 charger in North America is of type 1.

 

Yeah, that's one problem with such a large consumer market, it's hard to change standards once they're set in place. Small countries can just switch and be done with it, as we did with going metric. Owners of older Leafs in NZ, the most common EV here by far, need to carry Type 2 to J1772 adapter cables for public AC which luckily are mostly untethered. All DCFC have both Chademo and CCS Combo 2 as far as I'm aware, so they're covered. Early BMW i3 cars came with CCS Combo 1 but I understand BMW changed all existing vehicles to Combo 2 at their expense.
