Lucid Air as a home battery backup

[355spider]

That's a silly function that's you'd likely never use. Takes so much power to run a house especially hvac it would be completely impractical. Buy a cheap generator for the rare occasion you'll need it for that.

 

[Pragmatic]

Limiting energy out to 10-15 kw-hr per day, the The car battery could power most homes for a day or two.

The real benefit is in using the car battery to arbitrage electricity. Charging from a solar bank (or grid) when surplus energy is available and selling back to the grid when supplies are tight. Admittedly not all utilities currently offer opportunities to do this , but in the future more will.

Or...if a power outage is localized one could use V2H and then leave at a good time and go to a fast charger and reload. Whether V2H is a better choice than doing nothing, doing something (like V2L for refrigerator, etc.) or putting in a generator system is a different question.

Also, when we have three Lucid’s in the garage we could power the place for a while.

Any news on V2H?
It’s crickets since many months.

Looks like Kia is ready for bi-directional with the EV9.
Saw this today.

Kia EV9 will power your house for $6,440

Home backup capability could make allow the Kia EV9 to become a giant backup battery the equivalent to many Tesla Powerwalls.

Hyundai corp (Hyundai, Kia, Genesis) has figured it out. It is doable; the question is whether that is a priority issue for Lucid and I suspect it is not.

V2L is a decent alternative if one doesn't often get blackouts as one can use it to power refrigerators, etc.

Coming “this year” according to @SaratogaLefty who heard it from some execs

That will be great, if they can squeeze this before hurricane season, Lucid will save the all that depreciation from the car

 

[SaratogaLefty]

As Borski said I was told back a few months ago by a senior Lucid Executive that V2H would happen this year. Also heard from another Lucid owner that he was told by another even more senior executive that it would happen before year end. So we just have to wait and hope it does finally come to pass.

Here is Tesla's bidirectional charging page. It says something about "other EV's". https://www.tesla.com/powershare

One of the problems with the whole thing is that rather than all companies going by a given standard, each does it on its own. I have a Powerwall gateway. It has the information that Lucid would need. It gets information about my solar, power coming from or going to the meter, from/to the Powerwall, etc. My Tesla app shows all this, and Lucid could in theory use the Tesla API and work with my existing hardware. But it would make no sense since the Tesla API isn't part of any standard available to other manufacturers. It's not a matter of a hardware standard. The car can't just blindly send power to the grid through my home, but needs to know what power I need, whether the grid is running or a have an outage, etc.

Lucid should work at some point with the addition of their own gateway, but it's also approaching the extreme that I'd need the Powerwall for any extended outage. I'd like to have the ability to add the Lucid, and in theory have almost an indefinite power source if the grid is down. Chances of a week straight without sun is rare here, and solar should keep me going and recharge the car. But it's also something that I don't want to pay a lot of money for, given the lack of a real world need.

I'll give you a great example of where V2H is perfect: the coastal US where hurricanes are a threat. Generators on the ground can be inundated with flood waters. And you don't really need the power until you return home anyway, so an EV is a perfect solution.

But if it costs $10k to implement, then I'm getting a big assed generator, putting it up off the ground in a waterproof enclosure.

I added power walls to the solar already here when we moved to AZ. APS here does not allow export from batteries, only directly from Solar.

But the batteries do carry the bulk of the load during the expensive time of the day.

The power companies really don't like having to pay their customers. And the drag their feet on the inspections before giving permission to operate.

There's four aspects to getting V2H ready:
* Hardware that interfaces with the car
* Hardware that interfaces with the power company and with any solar systems and other batteries
* Software that ties it all together
* Regulatory approvals that may include forcing power companies to allow the installation.

I wish them luck!

In California, new home-battery-to-grid installations can be set to allow charging a battery from the grid, or discharging it to the grid, but not both.
If your battery can discharge to the grid, it must be charged only with solar power.
To get a rebate for its installation, the system must be configured to participate in an Emergency Load Reduction Program (ELRP) that can automatically discharge your battery to the grid at times chosen by the utility.

Some EV manufacturers are already participating in grid-stabilizing programs like this in other countries. I can only imagine the bureaucratic level of coordination and software it takes to accommodate it.

PG&E doesn't allow for it either. In fact, they'd punish you for it. They have no direct way of knowing, but if you sent power back to the grid with the battery, which the Tesla app would let you do, and got it back at night when the rates are lower, it would increase flow in both directions on the line, and the state mandated non bypassable charges would go up.

V2L should be much easier than V2H, uses some similar parts, and would be very useful to run a Refrig. during a power failure. Why not do it first?
The Gravity already has the needed technology available.
