Hi Tony,
Just to clarify, that was not me answering. I wouldn't know such things (or have the interest) without an engineering degree! ;)

The Andromeda Power ORCA Mobile charger can also work with mono-phase 240V input. With the 125A breaker you can actually charge your EV at a rate of 25kW continuously!
Look at the datasheet, Table1, here: http://www.andromedapower.com/uploads/ORCA-Mobile_datasheet_120111.pdf"...
