Oddly, my question got answered about 2 hours after I posted that message when I watched this week's episode of Motorweek. They actually had a segment on the show where they talked specifically about that exact same question! Time to go buy a lotto ticket.
Anyways, what Motorweek said was that the plugs for Level 1 and Level 2 chargers have been standardized, so any PHEV or EV will work with any charging station. They're still working on the plug standard for Level 3 chargers, but those are for commercial use since homes can't put out the power required for one of those... yet.
The reason I was wondering about this in the first place is because Austin Energy has a rebate program on Level 2 charging stations. They're doing some research on usage, and they'll pay for up to $1500 of the cost of buying and installing the charger, but they say you may have to swap your charger out for theirs (which presumably has some metering in it so they can track data), and I just wasn't sure if theirs would be compatible with the Fisker. Apparently it will. For that matter, we should be able to buy any Level 2 charger, not just what Fisker throws at us.
