Rivian needs to push V2H update

[HyperionMark]

My thoughts: I don't care either way.

That is some amazing insight and very additive to the community. Thanks for being a useful member to this site.

I would definitely be interested in exploring this, but the configuration of our house electrical system is not ideal for this (garage on the opposite end of house from the electrical panel/service entrance). Luckily we very rarely lose power, and when we do it is only for a couple minutes at most.

My R1T's vampire drain is still a concern. I wouldn't trust it to power my house without draining itself completely.

See? V2V is already a thing in the Rivian.

V2H might not be what people are really looking for. I think that is basically to buffer high demand. When the V2H unit senses a power outage, it will disable to prevent back power into the grid. Without panel changes and integration there won't be a lockout for powering the house during an outage.

Does anyone have insights on the implications to Rivian's battery warranty if V2H (or V2G) were enabled?

I have some experience with the Enphase equipment. I have a one-year old Enphase system that includes the IQ8s on each solar panel - the main advantage of the IQ8s over the IQ7s is the ability to power the house during a grid outage, as long as there's sunlight hitting the panels. Of course the power at any moment may vary. I can say that this "sunlight-backup" (as Enphase calls it) works really well for smaller loads up to microwaves.

I saw Generac combined efforts with Wallbox yesterday, it seems like everyone is working hard on their alliances, it would be nice to see some products for this and Rivian to turn on the option...

Guys as someone who has been in this Solar Battery space for over 15 years. The R1 series are all ready to go. The hardware is installed and the hold up is getting an approved Bi-directional charger. Rivian doesn't need an alliance with anyone. You can use wallbox or the new swapped chargers. These charges for reasons stated above are not readily available because the utilities need to figure out how to implement them just like they did when batteries became a thing for solar.

It's a policy issue, not a hardware issue. The other holdback is the wall box for example Bi directional charger is like $3500 and a standard charger is $400. For that cost, a generator is a better option and would lessen the life of your 100K truck.

V2V is a much more relevant use case if you ask me when you need help. Having a tow truck or another EV be able to get you some juice on the side of the road or in the backcountry holds way more value.

SMA inverters have this same capability.

I'm not sure how that works. Would it be something that one would have to purchase from Rivian? Or would the manufacturer have to license from Rivian? I would assume that nothing happens unless the proper handshaking takes place.

In theory, all Rivian vehicles have the hardware to support the CCS-standard V2x. There just aren’t any home chargers/integration units for it yet. Multiple charger manufacturers have announced plans, none are out yet.

The Ford F-150 Lightning’s home integration system is custom to the Lightning, it isn’t the CCS-standard, so other V2x CCS vehicles won’t work with it.

There’s no reason for Rivian to “release” V2x in software until the hardware is actually available. (Plus, they’d probably want to test a couple pieces of hardware so they can put that in the release notes “we have confirmed proper operation with the Enphare Bidirectional Charger” for example.)

Ford F150 Lightning have a V2H adapter that is offered by Sunrun. It is ~9k if I'm not mistaken.

Dont tell me hardware doesnt exist.

Ford's hardware is not compatible with non-Ford CCS vehicles. So yes, the hardware effectively does not exist. If Rivian's system is designed the same way, I will not be buying it.

CCS (ISO 15118-2 or 20 hardware) doesn’t exist in the wild - as that Ford Powerstation is proprietary to the Lightning.

yeah but Ford made it happen. All I'm saying is, if Rivian really gave a shit about it and used it as a differentiator, they could find a suitable partner like a sunrun to figure the hardware out.

I am a rivian owner so i don't wanna get into rivian bashing or defending. THis is a case of them not caring enough to make this happen.

For me, i value this aspect of emergency power backup as it basically means i will not need to buy a whole house generator for power backups in the event of a hurricane or a freeze in Tex-ass

with details on powershare coming out from tesla, I really hope that Rivian has the same capability that is behind a software lock. I'm not specifically asking Rivian to interop with tesla, but taking advantage of that 48A onboard inverter is such an elegant solution as compared to DC coupled systems utilizing ISO 18118-x. Having a 11kw 240v inverter available behind a j1772 plug is so much simpler wiring and cost wise than a offboard inverter, backup battery and a DC charger.

While, it makes sense that V2H would require some expensive inverter hardware as mentioned (Wallbox), I'm curous if similar expensive hardware is required for V2V (DC-DC)? The idea of a small portable electric 'siphon' is kind of cool.

I think so since the "source" car has to match the voltage of "destination" car's battery pack.

I don't think it would require an inverter but would require some way to throttle the DC voltage from the donor car to the receiver car. This could be done at either end. If it's on the receiver car, the existing circuits which manage DC charging from a charging station could be used.
