Quite probably none. I'm of the opinion that you can just have 2 flavors at a recharge point. (In the US, anyway, dunno about elsewhere). 120v, 20A, with the normal 3-prong plugs, and 240v, 50A, with the typical electric range/dryer connection. Something for everyone.
Oh, and will everyone stop saying 110v & 220v? It's 120v & 240v. (At least here in the US where it counts.
)
On the topic of 480v, (which is not 440v), the step-down transformer doesn't change significantly in price to achieve the voltage, it does when changing current capacity. The step-down in front of my parents house is only 2-300A at 240v, but it gets fed from a line that is somewhere around 19,000v. So a simple transformer swap, (not that this would be cheap, though), would allow for 480v in their neighborhood.
