Chademo does the rectifying, (DC fed to the car) so it all depends how it's built. Shouldn't be a problem if taken into account.

Isnt it possible to just wire L1-L1 and L2-N on the wall connector, like in the attached diagram (from the US manual). If ground is missing, just burrow a grounding spear. Thats how its done in Norway for Isolated Terra (IT) nets.

The problem is that it is a floating Delta, there is no ground connection. The WC uses ground as a safety check.

I have 600kVA 240 grounded B service at work and the only place the ground connection happens is after the POCO's CT on the bus bar.

if it weren't for everything being in EMT/rigid conduit, I'm pretty sure the previous tenants would've tried to ground another phase somewhere. I wouldn't want to have to change it to anything else. it would be quite the ordeal and after I'd have no additional function added.
