Thanks for the detailed response! Will definitely give that IEEE pdf a read.

> First, the most fundamental problem: Home electrical systems and the distribution grid are not ready for this.

I'm not as familiar with code for new buildings in CA, I know that they require solar on them do they not do solar to grid as part of that? That wasn't something I'd really thought of, I'd assumed most of the cost for that usually comes from retrofitting more so than if it's during the initial setup but haven't actually looked to verify that.

> First: Battery packs have limited charge/discharge cycles. If you use your car for V2G, your battery will fail much earlier than if you just use it to drive. Why pays for that? The warranty will not cover it, I can assure you of that. Also, think of the waste and recycling load that would impose.

It depends pretty heavily on the manufacturer, but newer batteries on higher end cars have pretty amazing cycle lifetimes, watching car enthusiests on youtube it's not uncommon for people to buy used tesla batteries from totaled cars for custom conversions or custom home battery systems.

> Second: I just spent money to fill-up my battery. And now I am going to let the grid drain it? Are they going to pay me? OK. They have to pay me enough for me to recoup my investment and more than justify having to spend tens of thousands of dollars when the battery fails. That power will be insanely expensive. Who is going to buy it? Energy rates are already ridiculously high. This makes no sense to me.

I'd fully expect to be getting that cost back + some small amount for the inconvenience back as credits on my bill. (I would mostly be expecting this for handling particularly bad peaks and not so much an everyday thing)

> Third: Range anxiety with electrics is a thing today and will be a thing in the future. Why drain your battery to the grid? This makes no sense from that perspective. It's like saying to your neighbors "Hey, I just filled-up my gasoline tank. While my car is parked, feel free to siphon off up to 50% of my tank.". Nobody is going to do that.

I'm not sure if you have an EV but for me range anxiety went away pretty quickly after buying mine, it's pretty much only for long range road trips that I have to pay any attention to range at all, though convincing people of that before they own an EV is pretty tricky (and there are people who need to drive hundreds of miles a day that don't work great with current EVs)

> My take on this is that people will do what they have to do given their circumstances. People have very random daily schedules. Some work at night, some have work and college, others might have a couple of jobs, after school activities, etc. There's a lot of variability built into behavior. It's like herding cats. In the end, I don't think behavior will make a significant impact.

Those people that have different daily schedules probably actually help as they're less likely to be charging during those peak evening hours.

From what I've seen the systems are pretty automated and there's a lot less for people to manage than you might think, it's more like setting up a thermostat where there's some initial work to setup a schedule but then it's just plug your car in when you get home and leave it plugged in and they can schedule the load so it's ready when you plan to leave and then if you have need to leave earlier than usual it's not hard to override it (though I do wish more EVSEs had direct buttons on them to control that type of thing).
