There's a lot of industrial 277V in North America that's a few volts too hot to support level 2 EV charging. It just needs to be knocked down to roughly 240V, and that's not that hard to do with a small bucking transformer, thusly, outputting 241V (close enough).
For instance at 48A, the bucking transformer is 36V x 48A = 1.7 kVA. Not a big transformer. So this is pretty achievable.
Note that the current economics are a little weird here - even though 48A is flowing through the outer ring circuit, giving 48A @ 241V (11.5 kW), and the transformer is drawing 6.2 amps, the 277V draw isn't
48A + 6.2A = 54.2A... it's actually
48A - 6.2A = 41.8A.
However, 277V-36V transformers are far less common than 240V-36V transformers. Is it possible to feed the bucking transformer from its own output? Like this
