Occasionally we'll have power outages to go along with winter weather at my house.
It occurred to me while investigating backup generators for my house that I have an extra 60 kWH sitting in my garage right now, enough for a day or two of backup power. Would it be possible to draw from the battery back through the wall connector as a battery backup? Obviously you'd need to install a transfer switch and shut off the mains in the house so you don't feed the whole neighborhood, but I'm wondering if the charging hardware in the car could function in reverse.
