Bi-directional charging?

[zipzag]

According to Wallbox they claim "Quasar 2 will seamlessly transition your home to vehicle energy when the power goes out." which tells me it's all automated, 11.5kW output. Granted it isn't released yet so talk is cheap, but they already have close to final versions built and they're really close to releasing them. I'm guessing it's going to be $3,500 - $4,000 but who knows

Can't replace 200 amp service with 11kw and no load shedding

From Rivian Q4 2021 shareholder letter....


This letter came out after RJ's video. So the latest appears to be that V2H and V2V charging are dependent upon their 800V architecture, which is not in any vehicles in production today.

That doesn’t say the existing architecture doesn’t have it… just that the new stuff does.

As I read this thread I started to think that maybe I should wait to install a Level 2 charger in my garage if two way devices are coming soon. But then someone mentioned that they’ll cost roughly 5x-10x the price of the current 220 chargers. With that in mind, and considering that power rarely goes out where I live, I think a couple new extension cords ready to plug into a Rivian in the garage would be adequate.

We have solar on the house and it has the same switch. I wonder if having solar makes vehicle to house power more complicated or less?

Victron is the only maker of inverters that can blend generator/inverter input with solar and battery, as far as I know.

The idea that todays solar inverters will be in place for twenty or thirty years always seemed farfetched to me. The panels will last, the inverters don't usually have enough functionality.

Agreed, it'll be interesting to see how Wallbox tackles this since they're close to production. I've been keeping a close eye on it as the potential of using the R1T as a battery backup for my house is very appealing to me (Thanks Texas Grid) and it would be much cheaper to buy a charger for 3-5K (guessing) than to try to get a decent battery bank for my house.

No, not explicitly, but At one time Rivian also said Max pack would be delivered first. They also said that a heat pump was not necessary because they are using heat from the motors to warm the batteries, but they are developing one for some reason. Rivian also at one time said that 300+kW charging would be available via OTA on their website, but claim has since been removed
(lots of reviews online say the Rivian has issues with thermal management at 200kW and peak charging rates are not maintained for long).

At the time the prototypes that RJ was referring to may have had hardware that was capable of bi-directional flow. Current trucks may have it. However, it may not be stable enough for public use, like how they haven't figured out a way to get tank turn to perform consistently enough for public use. So w/o other HW upgrades, the current trucks in production may never get an OTA update with bi-directional support.

Victron is great, there are others.

Sol-Ark is another top brand that can blend power. I have a Sol-Ark 15K and it's pretty impressive. It is on the high-end when it comes to cost, but it has a ton of features.

Might be a good question to pose to Monroe as they are doing the tear down of the R1T. They have never mentioned anything in the hardware that would be their for bidirectional that I have seen.

My take on the things I read is that the bidirectional charging, 800 volt, and 300 kw charging would all be coming in the newer hardware supporting the in-house motors.

Yes you can

seems a bit odd theyd change the battery charging architecture months from production. Not an easy change

Not change, but say it didn't pass QA... HW may be there, but HW is insufficient for production use and will never be enabled? Make sense?

Eh - it's part of the CCS standard. I doubt that but it could be the case. Either way - the way the press release reads to me shows that they are more touting that their own personal architecture is super capable rather than existing is not capable.

Being in Quebec, Canada i was looking at something like Tesla Powerwall for my home since we often have power outage from time to time. While sesrching, i found a company called dcbel out of Montreal, Canada. They have made a battery pack / home backup called « r16 » Called them up and said they are currently only selling their product to US market due to the high demand. It basically kicks in automatically when there is a power outage and power whatever circuit you have linked to it. It can apparently charge your ev as well.

could be something useful while waiting for bi-directionnal charging!

damn. sounds like us current and near future owners are going to be out of luck on V2H and V2V.

I disagree, I don’t think RJ would have said in a video clip that the production vehicles have the hardware needed if they in fact did not. I think they haven’t said anything about it yet because there’s no point in doing so; there’s no charger on the market that can do it yet. Chicken and egg problem on which comes first. I believe with RJ already saying they’ll support it, it’ll come once the chargers hit the market.

i hope youre right. but like someone else said, they also said tank turn would be an available feature.
