And the now, much revered Ford Lightning, that will power your house during a blackout…again DO THE MATH or stfu. Yes it’ll provide power for a little while, but then you have to charge it back up… it’s not even a good option for camping. Yes the Gasser ford with the PTO driven generator does these things. But the lightning claims are simply marketing for those who s uck at math and are gullible.

Technologically, it works and it makes sense. Average household uses somewhere around 800-900kwh per month. If you can dump 30kwh back into the grid, you negate the demand (actually even less just covering the peak period in the evening). Since most EVs are in the 60-140kwh battery bank range, if you haven't returned home on empty, you should be able to cover the evening peak demand or at least a significant part of it.

Economically is where it gets problematic. The expected lifespan of EV battery packs is heavily contingent on how many cycles you put it thru. For your typical commuter doing 20-40miles per day, it's maybe 10-20% of the charge cycle. If the grid is pulling the battery down by an extra 60-80%, you are wearing the battery out several times faster.

Rather than net metering, the power company would have to pay a substantial premium for peak period power dumped back into the system to account for the lost value of a worn out battery bank.

On older cars, you run into the problem where even if they cover the battery damage costs, if the car isn't worth enough to justify several thousand for a new battery, effectively, they've made the entire car worthless, so the premium would have to cover that also.

Very quickly, it makes more sense for the power company to install stand alone battery packs.
