Note that the 2011-2012 generation has a pretty wimpy cable gauge, so don't try to charge faster than 6kW.
That is an interesting way to get it done and it is a reasonable backup plan. I have the ability to swap the OBC safely if I bought a spare, but they are still very expensive from Nissan, especially for a 2011 car. Would a replacement OBC work out of the box? I've read that changing the BCM requires registration, do you know if changing the OBC with a junkyard spare requires something similar?
Have you logged the OBC can bus enough to enable a non-OEM charger to be used?
