Diminished real range 14 months in

[R.I.P.]

Wow I never used a forum to post anything about my Rivian I like the truck. I was just curious to see why my range is down so much, since I hardly ever charge to 100%.
I did not know it is illegal or something or that posts about range degradation expire or get out of range or something.
I don't need lectures about Tesla either. If you cared to check you would see engineer in my profile so I understand something about battery capacity.
This is obviously not a forum for me.

This forum is more palatable once you identify the "zealots" and block them.

That said, and this is simply meant as an observation, (it's possible that it is reader error on my part); but for an engineer, your test method would appear disappointingly unscientific.

Seriously, please don't take offense, and again, maybe I missed something in your testing procedure.

I did not test anything. I simply stated what was on the screen to see if it is wat others experience. If it is common I would not bug Rivian. Now I am a bad engineer on top of it. It is mind boggling. Please don't try to explain it is weird. I would rather do without.

See? I misunderstood.

Drive 68 mph on flat area with no wind in 70 degrees. You will get the expected mileage.

I just charged it for a trip to 100% and saw 285 miles. I will let Rivian take a look at it. I did not wanted to schedule service if 13% was a common degradation.

What I'm trying to say, and I think why some folks on the forum get frustrated, is because we see these degradation posts all the time. 285 miles is an estimated range you can travel and has nothing to do with degradation. As I said above, if you want to measure degradation that is the way to do it.

Your reduced range is most likely due to cooler weather, driving habits, or a combination.

If your concerned about degradation sign up for something like recurrent which will give you more insight into the battery health... But even that is not 100%.

Batteries don't care about range... It's energy. How much energy you can store/extract when new and how much you can store/extract now is what tells the tale.

You have an industry leading battery warranty too ?

As others stated, the range is a dynamic estimate with many variables. You could go into RIDE diagnostics and check the Battery SOH (State of Health) to get a better indication. Read this thread.

My R1T has 6K miles on it New in February 2023. Range in conserve mode is 285. That is 13% degradation in 6K miles over 10 months. No Super charged once on the only long trip I had. The rest is home charging. That is more than my Tesla over 4.5 years and 45 000 miles with lots of supercharge.

The reason I have a problem with this post is that an outright claim was made about the "fact" of a 13% degradation over only 10 months. There was no question posed here, and no uncertainty expressed - it was a statement of fact without any supporting evidence. This is how misinformation begins its life, and I believe in calling out misinformation when I see it.

There is also the explicit comparison to Tesla - why is Tesla brought into the conversation other than to portray the poster as someone who has experience with EVs and knows what to expect, underscoring the accuracy of his claim, and to portray Rivian as "worse" in comparison?

If the poster had a *concern* about the mileage he was getting, then a *question* about how to figure out if his battery was degraded would have been a reasonable start to a discussion. But a statement of "fact" is just something that is going to be picked up an repeated across the internet as "some Rivian owners are reporting battery degradation of more than 1% a month", and which will contribute to all the intentional FUD being spread about Rivian.

The poster dug up a year old thread yet apparently didn't even read it - if he had, he would have seen lots of contribution from lots of forum members asking questions for clarification and suggesting things (like tire pressure and alignment) which would adversely affect range. Instead, the poster expects all those things to be repeated in the response to his post so that he doesn't have to read a year's worth of information?

Yet this poster decided to ignore all those previous posts. Where is the statement that he checked his tire pressure and they were all at xx psi? Where is the statement about what speed he was driving, what the temperature outside was, whether he is driving on flat terrain or up and down mountains? Where is the mention of efficiency numbers, whether aftermarket tires are mounted, or a roof rack, etc.

If nothing else, reading this thread should make you aware that mileage is highly variable depending on conditions and driving style. (True on ICE vehicles as well). Completely ignoring these things when making a claim about "battery degradation" doesn't indicate any uncertainty from the poster about whether his claim is accurate, but also doesn't indicate any attempt to understand his range numbers.

Maybe I'm reading way too much into this, but it's a pattern we constantly see here that someone jumps on the forum into a really old thread just to claim that Rivian sucks and here is a "fact" that proves it, then disappears while that claim lives forever.

I think it's just fear and jumping to conclusions in most cases.

I honestly think EV makers should eliminate range estimates from the vehicle display for this reason. It should be a percentage readout only. Put the range estimate in the navigation instead with the disclaimer that it's only an estimate based on current conditions.

With all the misinformation out there about EV battery longevity and so on folks become overly concerned with the health of their battery. I think it goes along with the fear that 250-300 miles is just not enough range. People get hung up on the range number as some sort of limit.

Gas vehicles have their range estimates buried in menus if they have them at all.

If the world and all the people in it ran on logic it would be a much less stressful place ?

IIRC battery degradation is more about cycles rather age, especially at 1 year. I've had mine for 8 months, 9000 miles and I just did a 600 mile trip. On 21s this time and I got ~320 miles before I stopped to charge. Oddly enough almost identical to the mileage I got on 22s. Highway speeds between 70-85mph.

I charge mostly at home but use EA chargers when I'm on the road. I usually charge to 85% before the latest update. With the latest update I charge to 75%. When I'm on the road I charge to 100% the night before, and I always charge to 100% while I'm at my destination (Usually L2), and when I DCFC I usually stop charging around 70-80%. I base that on charge rate rather than %. If my charge rate drops below 120kW, I hit the road.

is that in conserve mode? what percentage or miles you have left at 320 before you stopped to charge?

Conserve mode, low suspension, and in relative cold (30-40F) It was a while ago now so I don’t recall how much I had left. I also sold the truck, I think on one trip I projected out to nearly 340 miles of range..quite insane. Comparatively my Lightning on the same trips have maxed out around 280 miles.

We have a 2017 Mercedes B250E with 40K (Tesla Powertrain). New range was 86 miles, now I get 82 miles. Battery degradation is something, roughly 1% a year in my case and we haven't babied it at all, lives outside in GA summers.

 

[Electrified Outdoors]

normal degradation over 3 years is between 5-8% as I have seen over many years of owning EVs. After the first couple years the rate slows down. The battery management system is very good and taking care of the batteries. This is why I really like Tesla and Rivian because they can push updates OTA. OTA updates have the ability to constantly tweak things vs the old way of having to take the vehicle in and have modules reprogrammed by techs. This means that the vehicles should have much better longevity.

The mainstream media fear mongering over EV range and battery longevity is what causes all this unsubstantiated fear over degradation.
