Your EV already has a big battery (well most these days do), and a high power inverter. It shouldn't take much extra hardware to make that system able to squirt its battery energy out to a changeover panel in your garage or cellar. That HAS to be cheaper and more convenient than buying yet another battery and inverter for your house. It's hard to imagine it costing even close to $8k. It might add (guessing here) 5-10% to the cost of the EV. That should make home backup power readily available to many homeowners who otherwise might think it wasn't worth the investment for the few times they'd need it. Add a couple of NEMA 5-15 or 5-20 receptacles to the EV, and apartment dwellers might be able to join in the fun too. Also, what a great way to power a robust 120v circular saw or drill away from home. (Yeah, I know that cordless power tools exist.) For example, you could buy a sheet of plywood at the lumberyard and cut it into the pieces you need right there in the parking lot, so that it fits neatly into your car. Not that I've ever done anything like that in a Home Depot parking lot, of course. :-) David Roden, EVDL moderator & general lackey To reach me, don't reply to this message; I won't get it.
