How common is 2-phase supply?

Yeh I get that. Your issue comes down to not getting what you expected which is frustrating and hopefully your complaint will lead to documentation changes from Volvo, but at least you haven't been put in a situation where the vehicle just doesn't work for you.

 

The volvo docs do seem quite poor. When I first saw this thread I googled for Volvo PHEV charging and the first hit was a document that clearly covered the limitations but the document you linked to doesn't.

 

Whilst I can't prove it, I suspect they are busily adding qualifying text where it previously wasn't provided. My guess is that it was there for previous variants, but was left off of documents covering the 2026 model year updates. Whether that is because they had intended to improve the charging rates, but then didn't, or because someone dropped a clanger - who knows.

Late to the party but 2 phase is pretty common in Europe. Typically oven wiring diagram. Options for single, two or three phase depending on the supply:

Clearly you are pissed off feeling decieved (fair) but I wonder how much difference the 3.7k vs 6.4kw charging will make to you in practice. How big is the battery?

 

The 6.4kW vs 3.7kW looks like a "true" 3 phase (vs single phase) supply to me because 6.4/3.7 = 1.7297., almost sqroot of 3?

Ignoring the PF, Power, kW (3phase) = VI*1.732, so 6.4kW requires a phase to neutral current of, 6.4*1000/230/1.732, 16.07A.

Power, kW (single phase) is VI, so 3.7kW requires 3.7*1000/230, 16.09A, almost the same as the 3 phase (obviously?).
