But unless I'm mistaken, it doesn't just reverse flow in a V2H scenario. You have to enable it via the console or app to export power from the vehicle. So if you're charging, it won't just start discharging unless they have a means to override your controls.
Next new California Law, they must be given access to enable this...

Tesla stock drops 5% after Q3 deliveries fall short of estimates

Tesla (TSLA) announced third quarter deliveries on Wednesday that slightly missed expectations, sending the stock down about 5% in early trading.

The EV maker delivered 462,890 vehicles in the three months to Sept. 30, up 6.4% quarter over quarter to mark the first quarter of delivery growth this year. The numbers also came in ahead of the 435,059 EVs the company delivered in the year-ago period.

But investors have also debated a “notably lower” annual vehicle growth rate, which Tesla warned about after the first quarter.



See. Here's what's odd. The official estimated "Street" numbers were lower than what Tesla turned in. But evidently there were whisper numbers that nobody published. They beat the numbers that were published but not the double top secret probationary estimates... :)

The way these work are all on an opt-in basis. At least so far. Called VPPs or virtual powerplants. Instead of a few hundred Mega packs in a field, you get a few thousand customers with some form of storage, Powerwalls, or maybe EVs, to sign up.

You get an alert saying there is a VPP event and letting you know what they are paying. Then you opt in and set how much power you are willing to commit. And you can bail at any time.

The "part of the grid" thing would concern me doing something like this. Remember when NMCI computers were going into thermal overload from the constant disc activity? The chances of fire are greatest from physical damage, but while charging is the 2nd most likely time for lithium based batteries to catch fire. My hobby lithium batteries are charged in fire proof sacks and stored in fire proof containers.

I think the most common cause of EV charging fires are poorly done charging systems.

Being a race to the bottom its hard to figure out which are the good ones and which are the cheap "it'll do" ones.

I have seen model aircraft batteries go off while being charged on good chargers, haven't had a fire myself but some of my friends have.

This attitude is from someone who has installed dozens!
Yep. But there are hundreds or thousands not installed by someone like that. And that's the problem. I would venture a guess that Harry Homeowner is the number on cause of electrical fires. Would you agree?

Oil changes are one of the easiest mechanical jobs in a car. Yet hundreds of cars every year are damaged by home oil changes gone wrong.

Most likely if you can afford an EV you can afford having someone who knows what they are doing install it.

Yes and every year there are folks that die in auto accidents, even thought they are licensed to drive.

Please try again.

In my world most electrical fires are caused by appliances and loose connections.
The electrical code a book that states the minimum allowed is still over protective that is why old work rarely is a problem .

Sure, you most likely can, that doesn't stop folks from trying to DIY it. I never said anything about old work. What I'm saying is that when an EV burns at home, its most likely caused by an issue with the charging system installation. You can believe that or not. You choice.

I doubt that seriously. But you believe what you want.
