Rivian Smart Charging Arrives in Next OTA Software Update

[strykerwsu]

SCE pays $.02 / kw generated by solar so its always better to charge while my panels are producing rather than pay $.37 at the lowest nightly rate.

This is amazing to me and understand why you have solar. My bill would be $1,500 a month. With all the data centers sprouting up I keep telling everyone around here that doesn't pay attention the $ increases are coming.

curious what data south Louisiana will get. Entergy currently does not have ToU

Smart? Seems like just a timer.

Will it communicate with Powerwall to know the PW battery is 70+% and solar is charging? Limited to the home address or even multiple addresses?

I believe Tesla has something in this area.

I posted on reddit, but I wish this can be setup to talk to my solar and only charge on excess (adjust charging rate) I dont want to shell out money on an OCPP charger for this.

You can do it with a raspberry pi.

Please expound, I have a pi zero sitting in a drawer unused.

Does that mean you buy 100kw at .37 and sell 100kw back at .02 or is it one for one and get paid .02 for everything over 100kw?

Sounds like v2x is where it's at using a big car battery to buffer.

And I thought La was bad with a .03 avoided rate and .12 payrate…seems like SCE could pay up more than .02

Maybe it's time to buy a NG generator and make our own power, lol.

Small form nukes are an option also.

But seriously, if the cost of fuel becomes more reasonable, a NG generator could be the cheapest way to power your house. Seems ridiculous, but that is what they have created.

How’s this different than scheduled charging we already have? My rates go to the cheapest from 10am-5am so that’s what I have scheduled.

 

[TexasBob]

We have one rate every day.

As do most people

Wassym from Rivian confirmed that Smart Charging is officially here and rolling out with the next OTA update.

Tweet by Wassym:

80%+ of EV charging occurs at home, and 70%+ of those charging sessions are not aligned with the lowest utility rates.​

​

Methinks Wassym is full of cr@p. According to the EIA in 2023 (latest data) 11% of residential customers had time of use rates.

Only 11% with TOU rates? That’s crazy. I‘m on a TOU billing plan with the cheapest rate, in the summer, from 12-8:00 AM (about $.079 per kWh). It goes up to about $.089/kWh until 6:00 PM. From 6-9:00 PM it goes to almost $.50/kWh. No chargie car during that peak time Winter rates eliminate that 6-9:00 PM Peak Time spike and top out at that $.089/kWh rate. So, in the winter it pretty much doesn’t make much difference when I charge.

On second thought, the reason only 11% of the people had TOU rates in 2023 may be that not that many people had EV’s back then. As the EV‘s become more popular, I‘d imagine more people will be taking advantage of TOU rates, where available.

Most people are on flat rate at a national average price of $0.16 or less. I am on flat rate at $0.128/kwh.
From the Chat GPT analysis of the EIA Dynamic Pricing 2023 spreadsheet (2024 just out this month but too preliminary says it should not be used to calculate stats totals).

The 2023 final EIA-861 Dynamic Pricing data shows:
15,604,253 U.S. residential customers (households) were enrolled on time-varying rates (TOU, VPP, CPP, CPR) in 2023.
That’s ~11% of all U.S. households (using ~141 million residential customers in 2023).
The interactive table I generated shows the state-by-state breakdown (TOU, VPP, CPP, CPR, and totals), so you can see where adoption is concentrated.

California unsurprisingly dominates, but you’ll also see contributions from Arizona, Michigan, and a handful of others with pilots or default TOU programs.

Here’s the split from the 2023 final EIA-861 data:
California: 5,930,557 residential customers on time-varying rates
Rest of U.S.: 9,673,696 residential customers on time-varying rates

That means California alone accounts for ~38% of all U.S. residential TOU/TVR enrollments in 2023 — confirming that the state’s default TOU policy drives a huge share of the national total.
