Hi Jay, I have a 1994 US Electricar S10 factory conversion that is expecting a standard 120 - 240 AC input at 13 Amps and all I had to do to add public charging was to add a J1772 inlet plus a diode and resistor on the pilot input. The current draw ia always less than public charging is offering and the only issue left is that I did not yet install the inlet, it is just a cord converting J1772 inlet to a standard plug for my regular charging cord. People are laughing when I pull up to a meeting with public charging and I run the cord from the charger into my driver window, plug into the inlet with a cord dangling from it, where I plug in my regular charging cord that runs out the window again and disappears behind the gas cap. Realily is that I have used this contraption maybe 3 times till now as I always plug into a wall outlet at all regular days and nights.
BTW, most public charging is delivering 208V as that is the phase-to-phase voltage of a 3-phase system that has 120V phase to neutral. You find 240V typically only in the residential environment where you receive 2-phase 120+120. Recently I have been charging off a standard commercial building's 480V 3-phase system where a single phase is 277V (often used for overhead lighting) and a little step-down auto-transformer fabricated from a dry type transformer with 240V primary and 32V (2x16V) secondary, both primary and secondary windings in series for the 277V input and tapping my 240V output off the primary, gives me a healthy 240V in an environment where otherwise only 120V is available...

And the fact that the TSM2500 charger and EVCC talk to each other over a simple local CAN bus connection makes things nice and easy, without having to wire up a lot of relays, etc... Plus the TSM2500 is dual voltage, so you can still power it from a regular 120 volt RV inlet if you want. (and I like the fact that the EVCC supports up to 4 diffeent "mode" settings, so I can select between slow charging to 80%, fast charging all the way to 100%, higher voltages at low amperage for top balancing, etc...and a 12 amp mode for opportunity 120v charging.
