(Just a far side dream, at this point.)
Will OpenEVSE work if I input 120v-240v DC? I am dreaming making a DC battery pack for occasional suppliment charging.
Hypothetically, The OpenEVSE power supply will work on DC, The relays/contractor would have to be 12v DC and not one with an AC coil. Some safety checks may have to be disabled... However, there is no telling if the charger on-board the vehicle is compatible.
