240V of course.

That's not so bad then.  In the US 60A service was once common, these days
it's only seen on older homes.  100A is the usual, while larger homes can
have 200A service.  Even 300A has been done, although when I've seen this
it's been in the form of a base 200A service with a second,
separately-metered 100A connection.


is gradually coming

Concorde has a lead-acid AGM that can take C*4, but it's an odd one, and
still nowhere near what A123 is promoting.

I'm watching and waiting.  I don't have a rapid-charge application, but I
definitely have room for a lightweight engine starting battery.


sufficiently daft.

By putting three windings in a stator, of course!  Cute little thing, puts
out just under 250W at 9,000 RPM.

It took me a few go-arounds to realize what was wrong.  I feel like I should
apologize for not realizing earlier.  When you mentioned 3-phase power, you
were talking about the only kind of 3-phase power system you knew about,
which is a high-current industrial power service.  I like to think you would
have been more specific if you had knowledge of more diverse 3-phase power
systems, such as the 3-phase alternator in my motorcycle.

sufficiently daft.

My dad has wired homes with 2 full  400 amp services.
200 amp is almost standard now and 400 is getting common in some areas
- particularly if electric heat is used (not as common as it used to
be)

A common 240V socket can supply... <sigh> why bother? It's all stuff
you should well know if you were debating in good faith.


Just another fractional truth from the master of such. The fact is
that a useful electric vehicle for many could be practically charged
overnight.

   Agreed, assuming that we are only talking about power available to the
typical USA home power service.  The ability of USA's grid to handle
millions of those large chargers is another matter.

Would require a massive upgrade of generation, the grid and local wiring.
