Rivian R1T OWNERS MANUAL Guide is here! ?

[Lil'O Annie]

Someone is getting their truck this weekend or Monday.

Speculation or fact?? ? And if fact, how do you know?

I thought the Motor Trend guys and maybe also @DuckTruck mentioned there were about 4 regen settings, but according to the manual there are only 2 (high and standard)

So I guess I can't just pull the plug out?

Stop a Charge Session

1. Go to the Energy menu
2. select stop charge
3. press button on pull handle and remove.

If MotorTrend is right, that's a very impressive average charging speed. Assuming 133kwh total, 60% means nearly 80kwh. In 30 minutes. So an average rate of 160kw.

Just better than disappointing for me. Just shows they are being very conservative with their charging curve in all aspects. Nonetheless good to see.

Speculation. But so many signs pointing to that that I'd be surprised if I'm wrong.

I'm glad the guide points out the tire. Man...that wudda had me stumped.

Looks like Gear Guard will act very similarly to Tesla Sentry Mode and will record when activated and under these conditions.

I feel like they would call out 800V in the safety warnings then...

So that calculation is from me (in reddit) for the 160kw average through the 20-80% curve.

Someone I know works with Rivian on charging tech (been in the industry for a long time, so has worked with Tesla, Nissan, Kia Hyundai, GM, Apple (!?!), etc), and he mentioned to me that everyone uses parallel pack charging to achieve the high charging speeds, even eGMP and J1 (Taycan/eTron GT). Ultium is also technically 400v but will use parallel pack charging in 2 banks to achieve up to 300kw speeds on the Hummer EV. On the Lyriq where there's serial charging, it's only 1 bank, and hence the 150kw charging speed limit.

I heard somewhere that the Rivian battery pack wiring config and inverters allow parallel charging.

For the EVs I have seen charging, the button on the charge handle that will stop charging.

For the Tesla, regardless of a Tesla cord or a J1772, I just hold the button until the indicator light is white then extract the handle. I can stop charger from the charge screen in the car or the mobile app but I never do.

I'd be surprised if this is not similar.

Bummer about March 1, 2022.

That's interesting. I should go back and see what the taycan shows for the battery voltage in the EPA submittal.

Actually, both of mine require you to unlock the car first if the car is locked once you start charging.

Air Compressor comes with a "clean up" mode where you can use it to blow debris off of things or out of the bed!

I never tried to stop the charging with the car locked as it unlocks when I walk up to it. I will try that next time. I know the car has to be unlocked to remove the handle (or adapter) from the socket.

This was more referencing having to stop the charging from the UI, you do not need to do that correct?

They have a sense of humor....

That's a common glyph. Volvo uses it, too. I've heard it referred to as "turtle mode".

The Taycan can also be 800V, but still have it in parallel configuration. In speaking with the person I know (with 20+ years in the EV industry), he's far more knowledgable about this topic than I am.

Found one of my old convos with him:

Well if you split the pack and parallel the you need higher current to support the high power. If you put them in series you need more voltage. Current apparently is more expensive because of copper. In series it’s 2x the voltage but half the capacity. The key is half capacity so you can charge faster. Everyone doing 800 VDC charging is doing it

He also has a hot Take on Batteries and Toyota

There's a fundamental technology problem with lithium ion batteries which is you would never put such a huge battery pack into a car with such a narrow operating tolerance. batteries don't like temp extremes, they don't like uneven temps, they don't like fast charge or discharge, and the chemistry isn't well understood...

At the same time, fuel cells face some of the same problems too. I personally think Toyota got caught with their pants down and didn't get a battery partner in time. My friend who works for Toyota has been saying that Toyota USA has been begging Japan for a BEV...OR the internal combustion contingency at Toyota is more powerful than at other companies.
Japan is all about the tech, but they do stupid stuff because of tradition...
