Seth, The contactor in a L2 EVSE is rated for AC typically, though it might be simple to replace the contactor with one that is rated for DC, typically the difference is the distance and speed that the contacts open and the magnetic blow out to quench any remaining arc.
For the charger in the car to work, you will need to provide something that it will accept. Likely the modern car's chargers will accept DC but since they have a minimum of 100V AC (Japanese standard) I would expect that they will have difficulty (or simply refuse to charge) from 91V DC. If they do it might be at much lower power *OR* at increased power if the charger is of the "constant output" design that killed many early Vectrix chargers if you plugged into an extension cord or an outlet that sagged too low, so the current went up too high and blew it. Providing 183V DC will likely be better. Even better but less efficient would be to use an inverter to create AC power for the car to plug into normally, as this will guarantee that it works without risk of operating outside normal limits. My EV has a 120V pack, so I installed a (cheap, used, no batteries) UPS from a server room that takes a 120V pack and generates 3kW of AC power. This is my solution for home backup power in case of a power outage or if I need to power anything while on the go. The same 100 ft extension cord that I have for plugging in to charge, I can use to deliver power from my EV for backup. If necessary - to rescue a fellow EV'er - if he has time to wait around.

Those are 2 good leads....what I mean is, I could bring 18.2 KWh of Thundersky LifePO4 @ 182 VDC (or more likely half of that - 9.1 KWh @ 91 Volts) 50 or 25 100Ah cells....and I would like to go into a L2 charger like an upgraded Leaf charger. I have not ruled out buying a hefty off-grid inverter. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
