I still haven't figured out KiEV's issue. Does the breaker trip during the safety tests, or after the tests when the car engages the contactors to start charging?
For both KiEV's and the poster on Nissan's facebook page, there has to be something mis-wired or a short somewhere. Replacing one of three components should solve either problem, and those would be the battery pack, EV-ECU, or the QC port and harness itself. If the data wires on the harness are bad/shorted, that could cause the car not to restart. Shorted power cables would cause the quick charger to fault/trip the breakers, so would reverse polarity within the pack (though that would do it after the safety checks).
The only QC issues I've had to date were CAN errors, some alarming pops, and one unit had a shorted power module, and these were all on a pair of Signet units (which through a series of changes and firmware updates, have mostly been resolved). Nothing was the fault of the car, though.
