I so much want to charge my car from 100 to 300 VDC which I am sure will work fine, since the first thing it does is rectify to DC before any other DC/DC conversion...
EXCEPT that you just never know where in the EVSE to car chareger some engineer may have "assumed" AC only so that he could open relay contacts without having to worry about arc suppression. One mistake and you toasted it. But I sure wish MFR's would spec if their J1772 port would accept DC as well as AC. Rememebr almost all modern supplies of any kind are made to cover 100 to 240 VAC and the ONLY reason most of them do not mention that the can also work on DC is because they did not do UL TESTING for DC. And the reason they did not do that is because there is NO MARKET (yet) for using 100 to 330VDC at home... though EVERY universal supply with a 100-to-240 VAC rating will almost always work* just fine on 100 to 330 VCD because that is what it is internally when run on 240 VAC. * JUST make sure it does not have an ON/OFF switch in the line, because that will certainly fry the first time you try to turn it off. WHY my fascination with DC, because I have 16 kW of DC solar in my yard that works fine with the grid. But when the grid goes down, I want to be able to tap into any voltage I want and be able to charge the car.

Many AC to DC converters will accept DC voltage I use one in my EV for the 12v out system. It takes the pack DC 160 volts and make 12 volts DC for the auxiliary power. There is a formula to calculate AC to DC equivalent voltage you can Google it. I believe 110 volt AC is equivalent to 170 Volts DC but you would need to check that because this is off of memory. Not all AC devices can use DC you will need to check the specs and maybe design to see if a particular product will work. I imagine it would be costly for a device that puts out 100 amps or so... level 3 DC fast charge is 100 or 125 amps I believe.

Google seems to know of one, for $24,000 - not for me :-) I have 18.2KWh in Thundersky cells that I could use.... Or even a Level 2 charger that will take DC....
