V2G standard 15118-20

[Joacchim]

A standard has been established for bidirectional charging, ISO 15118-20. Does the R2 comply with this standard?

I'm waiting for the enphase bidirectional charger to hit the market.seems like it's been "soon" for a while now... Enphase Bidirectional EV Charger | Enphase https://share.google/iP1Bc3VRjjbQjXf5w

"Designed to ISO 15118-2 and 15118-20, supports OCPP 2.1, V2H, and V2G". Wish they would all just pick a protocol...

I have received advertising email from Enphase all summer about their new bidirectional charger - IQ EV Charger 2. And, I understood from sources that it is available in the Bay Area but I have been holding off on adding it until I know for sure what vehicles it will work with. And so I was not given a timeline for order to installation.

I was told by Volvo that the EX60 “should be compatible“ and to check the list at my local Volvo dealer of “tested and certified” bidirectional chargers (or words to that affect).

In an online chat that I had this week with Rivian, I was told there is still no “published update available” on when bidirectional charging will be part of the R2 while being assured that the launch edition will be compatible (again, something along that lines). I was also informed that there is no such information available yet on EVSE standards or compatibility by Rivian (as opposed to proprietary solutions)

I imagine there's more to installing a bidirectional charger than just plugging it into a 240V outlet. Are power companies subsidizing the installation costs?

as I recall, the federal tax credit/deduction paid a flat 30% and remained available for chargers installed by the end in June 2026.

The other one (State run) is a rebate thru PG&E that (1) tapers off on how much is given based on your AGI and (2) is only available for specific ZIP Codes.

This is a good next step but keep the enthusiasm in check. Installation will be expensive and unless you are off grid the utility will need to be involved. As @sac602 said, it's not just plugging into a 240 outlet. Although we own the battery, feeding current back to the utility requires approvals and additional hardware. See what it costs for the GM solution ($10k ish installed). If you have solar or battery backup, you may already have some of the hardware. Then there is the auto manufacturer side. The drive battery warranties are based upon years and miles driven (which represents charge cycles). If the EV battery is to also be used to power a home, the charge cycles increase without miles and the current battery warranties go out the door. I am sure v2h will is coming, but it will likely be a while for Rivian.

Based on reports in this forum, the R1 seems to comply with that standard because some members are using the R1 for V2H. It is reasonable to conclude the R2 does also. The problem is there is no official confirmation from Rivian that it is supported.

Rivian said they will make an announcement this year (fall or winter at this point) about V2X support. Will they? Inquiring minds want to know.

Is it 2022 again?
