Thanks for testing and sharing!

I would find it interesting to learn their rationale for many decisions.

I think it's because a lot of people aren't reading what I wrote or because their own preconceptions are coming into play. Either way, it's a real disincentive to write a post which could potentially help people by providing objective information and documentation. Thanks for the feedback! I...

I'm pretty sure you'd lose that bet with outside temperatures over 100℉ and a long DCFC session provided you are looking at an objective measurable difference versus a subjective appreciable difference. Why? Because even if the charger can deliver at least the maximum the truck can accept, the...

C5?

I provided both screen shots. Please, PLEASE read the first post of this thread and look at the pics. The battery had been heated by buggy preconditioning to 105°, as I wrote in that first post: “IT HEATED THE BATTERY TO 105°! So I went back to the energy screen, canceled that, and used...

It is in the first sentence of the first post. “We’re in the high desert, the exterior temp says 101° and the battery shows 100°.” With a screen shot showing that below the text. The following is definitely not directed solely at you. It is really frustrating to have to continually repeat...

Exactly! I’m not claiming to know exactly what temperature or range of temperatures is targeted in every scenario. My expectation was that it would cool the battery based on past experiences with the battery at or over 100°. I was surprised when on-demand preconditioning started heating the...

Yes, from post 15: “This is clearly a bug, which is why I wanted to warn people about it and why I reported it to Rivian via the app.”

I never wrote that Rivian engineers don’t know what the best temp is for battery charging. As I wrote in the first post, the preconditioning or “Prepare for fast charging“ behaves differently if manually activated via the new button on the Energy app (updated with the most recent release) versus...

I never said I knew that so why would you question me as if I did? Read what you quoted and you’ll see I wrote that I think 75°F is the ideal on the battery temp gauge. I never claimed to know what the target temperature is. Just that I think the 12 o’clock (top center/middle of normal range)...

It’s good to know that it can work properly. We recently went to a Gen2. Did you see the manual preconditioning trigger cooling in your Gen1?

I think it’s safe to say that the expectation was that it would do the same thing as the automatic pre-conditioning: cool or heat the battery to optimize charging time. Tapping on the button doesn’t say anything about heating only and, even if it did, then it shouldn’t blindly heat the battery...

In hot weather the battery needs to be cooler rather than warmed and letting the car handle it isn’t always an option. Some of us use chargers which aren’t recognized as changers by the Rivian navigation and don’t trigger the automatic preconditioning.

Right, and going from 100° to 105° wasn’t a huge increase but 100% of the energy used to do it was wasted and it made the charging session last that much longer because I started at 100°, it heated to 105° before I stopped it and it only cooled to 103° by the time I arrived at the charger...

Apparently it will heat the pack rather than cool it when manually activated, but cool the pack when a recognized charger is entered as a destination. While that may be a minor coding error which is easy to fix, the effect on the charging session duration can be very annoying for people on a...

I think 75°F is the ideal (top or 12 o’clock position) on the battery temp gauge. I don’t think that pre-conditioning actually targets that but maybe tries to get within a range of it. I know our Gen1 would get down to the 80s. Edit:typo

Funny because it’s true.

We’re in the high desert, the exterior temp says 101° and the battery shows 100°. I used the new Energy screen “Prepare for fast charging” button to lower the battery temp on the way to charge. I got a little chuckle at a minor coding error when the screen showed “Warming battery for faster...

We all have our likes and dislikes. The world would be pretty boring otherwise. The color-matched wheels are what caught my eye first and I suspect the designer created the look with the color-matched wheels in mind. Graphite was probably offered for people who like a more typical look and/or...
