Cybertruck needs to have vehicle to home charging (V2H)

[tidmutt]

folks also shouldn't incorrectly assume that V2H means you can power all of your home just because the V is plugged into the H

there will be load limits. many homes exceed those load limits when running 'normally' (if only in spikes, but spikes are the ceiling)

it's in effect a critical load panel, with that critical load dictated by the limits of the vehicles max output

Yeah, I've wondered about that. What do you do? Disable appliances until the vehicle and supply the load without a tripping a breaker? I suppose you have to do what powerwall installations do now. Maybe there's a poor man's version of that? Break trips a bunch of times until you figure out what you can run and what you can't? Maybe some kind of display to indicate the house is approaching max load. Still sounds better than nothing at all?

I'm no electrician, but with that caveat: my understanding is that the code requires a critical load panel; that critical load panel will be "matched" to the available load input; it's at that stage homeowners have to make decisions, if any, regarding what is powered; add in a couple of HVAC units and real quick you'll be bumping into the ceiling.

I haven't started my genny-plug/critical load panel project yet, because there are a few new products on the horizon that I am waiting for.

But for my home, I'll be selecting only one of two HVAC units (which will provide a small 'wing' of the house with heat/cooling), the kitchen, and a few other random outlet zones (e.g., where my wifi/connectivity occurs, etc.).

That will leave a lot of things out of power.

There are *out* of code ways to go about this differently, and as I understand it some of the new 'smart' panels would provide greater flexibility ... all it takes is more money.

Sounds reasonable.

I think keeping the fridge, communications, some kind of cooking/heating and/or a/c (depending on climate) powered are the critical items. Having done without power, those were the most painful to do without. An outlet to keep devices charged and you're riding out a power outage fairly comfortably and safely.

Seems like Tesla a/c systems would be ideal here, Musk previously talked about more efficiently controlling zones of the house based on occupancy. Imagine a system that could configure a minimal power zone where climate control could be maintained with minimal power usage.

This is all a long term play, but enabling EVs now, would mean more people benefit, especially those with less money that may be purchasing older EVs in the future.

In some respects AC units seem the next frontier.

The problem being that the best AC unit is only as good as its existing duct work and related system design beyond the unit.

So, for folks like me (in a 1967 home), that smart of a unit would be (expensive) lipstick on a pig.

Can sit on your hands for 10 years, and then say we need to catch up.

There will be more excuses in the future, because that's what ossified companies are good at.

That's what was documented in the links you sent, please enlighten us and stop with the cryptic msgs. What features do you allege the original Roadster was capable of? Did it have outlets in the car you could plug into? Perhaps just the cigarette lighter? Did it have the ability to sync with the grid and export power via the charge port? Come on man, stop with the non-sense and tell us what you are arguing for

There's nothing cryptic about my answers. It was capable of V2H.

No. Not that I know of. The charger was bidirectional.

Did it have the ability to sync with the grid and export power via the charge port?

Technically, as it used the motor controller. I don't know that it ever was demonstrated to a customer to do this.

What's cryptic about that? I don't have to know details to know, 'Yes, the Roadster had V2H capability'.

I think a backup generator is way more useful and cheaper than trying to power your house with a EV. V2H is pretty gimmicky imo and a waste of money to add to your home.

No. A generator is super-wasteful, especially while idling. My neighbors ran out of gas for their generators while I didn't - because mine only ran a few hours a day to recharge a battery.

Having a truck with V2H would mean skipping using the generator altogether or being able to go even longer before needing refueling. And that's all the better.

Not to mention the exhaust.

V2H would be free for me if the Cybertruck has it. Well, except for the same connectivity that a generator has. I don't see how you can buy a generator for free. My truck can sit plugged in for a few days if necessary. At least I won't have to maintain a separate generator.

Sure, Ford has it easy. All they need to do is come up with millions of kWh of batteries, while everyone else is scrambling to secure millions of kWh of batteries. Of course all of their competitors are scrambling to do the same thing so it’s not exactly a “buyer friendly” market. Meanwhile, Tesla has been working on securing batteries for 15+ years and is setting up their own in-house production.

No problem at all.

Exactly. Batteries are not a major problem for Ford and shouldn't have affected their ramp up. How many EVs have they produced this year? They ARE also building hybrids such as the Maverick but It's almost as if they have chosen to slow-roll production of these less profitable EVs and Hybrids which makes sense from a stockholder's position... I ordered my Ford 10 months ago now. Yes, I've been waiting on my Cybertruck a lot longer but Ford had already been producing their truck for a year when I ordered it so such a long wait was NOT expected. I was hoping to drive the Ford until my Cybertruck was built.

Batteries are no problem

EV Battery Supply Unlikely to affect production

Personally I want V2H/V2L for convenience during local disasters, maybe once every 2 years or so. If my grid was dropping monthly, I'd have the generator or Powerwall.

The issue with V2X is that eventually, there will TWhs worth of EV batteries sitting around at any given time, most of which will be plugged in somewhere. Do we then continue to invest billions into more grid-level storage? Do we have rolling blackouts for high-peak areas instead of tapping into this resource?

the catch-22 is that, it’s either invest billions in grid-level storage, or billions in grid-level adaptation to distributed storage

I just went simple if power goes out I plug in the truck. Low cost setup. 2 x 240 volt 30amp 8 x 120 volt 15 amp curcuits. This cost me a total $1,100.00 CAD. It helped that my panel is in the garage.

Keeping the Home Heat and lights on during winter blizzard power outage!!! Calculated 200 hours run time with 30% battery at cut off. Will vary by load use.

You are INFURIATING, OK, you don't have details, thus you only think you know. got it. gonna block you now so we can end this

Running your house off of a giant frozen battery is going to seriously affect run time.
