> Electric cars mostly don't have the circuitry to do this yet Electric cars do have the circuitry to do this. It's built into the CCS protocol which nearly every EV speaks (US and EU). And it's not hard to imagine how this would work. Two big connectors on EVs can ultimately be hooked pretty much directly to the battery. When you plug in, you'll hear a giant "cachunck" which is the relay switching to DC charging. If you want to turn that into a vehicle providing power, the action is exactly the same, "cachunk" the relay which completes the circuit and have the charging station convert that DC power to AC. That's where the actual equipment gap exists. AFAIK, it's basically only ford that's producing a V2H charger. Enphase has one announced since last year, but I've not really seen anything about it since the announcement.

Tesla has a V2H/V2G (Powershare is the name Tesla uses) available for Cybertruck owners included as part of the vehicle purchase. I am still waiting on mine, despite receiving my Cybertruck almost 6 months ago. I also have the Ford equipment from when I got my Lightning, however finding a competent installer has been impossible. Right now it's collecting spiders in the corner of my garage.

  Do you have anyone that does home battery installations? It should be pretty much the exact same process to install one of these. It may be somewhat new tech, but ultimately it should look identical to battery controller install.

  Don’t forget about airplanes, you can fly in competent installers, some may enjoy the trip :)

  A Lightning and a CyberTruck? Have either touched dirt? :)

    The Lightning has plenty of times since I am confident I could get it repaired or replaced easily. The Cybertruck... not so much.

      Good! I had to ask. I’ve seen multiple Cybertrucks driving around my neighborhood and I’m pretty certain none of them will ever touch dirt. I hope you enjoy both vehicles!

In Switzerland it's also forbidden (as of now) to even think using your EV as external battery. The energy companies are fighting tooth and nail against people becoming independent from the(ir) grid.

Is it in the CCS protocol? My understanding was that the F150 used a custom extension in order to do its thing where it will power your house. And even they don't feed back into the grid, which would require synchronizing the A/C. If there's already a protocol built into CCS for vehicle-to-grid then that's great news, but manufacturers would still need to enable it. There have been some test deployments of vehicle-to-grid in the US from Leafs since they use CHAdeMO.

And even they don't feed back into the grid, which would require synchronizing the A/C. Both the F150 and CT have onboard DC->AC inverters. This, IMO, is a bad move. It makes way more sense for the inverter to be a part of the house. However, the onboard inverter does make it easier to integrate with generator switches in panels. If I were to guess, the reason we've not seen a charger/generator combo has more to do with the complexity of battery voltage platforms. Unfortunately, CCS does not specify pack voltage which means any inverter would need to handle anywhere from 600->900V from the car.

Having the inverter in the truck makes it useful for construction sites where you need electrical equipment and utility power isn't connected for whatever reason (a good one is construction hasn't gotten there yet; but also sometimes 240v tools are needed and there's no convenient access to 240v), and makes the truck a drop in replacement for a portable generator that people may already have.
