Kyle heard that the new software version for Rivain R1T (2023.10.02) improved the charging thermal longevity and curve before the battery pack hits max temperature and derates. Kyle also found that they way the charging power is being derated has been updated as well as the messaging during these events being deleted.

Thank you, Kyle, for giving your videos proper titles instead of doing something like: "We tried Rivian's new charging update and THIS is what happened!"

@justinstewart3248 Год назад

Oh and the worst click bait thumbnails that only say “IT JUST HAPPENED”

@ronb4633 Год назад

Kyle, I have 55k miles on my Taycan and 2/3 of charging was DCFC. Still getting 265kW charging when I find a good EA station. Car preheats to ~100F reliably. It is a road tripping monster.

@Jeddin Год назад

So the software update is really just removing more temperature information rather than fixing the underlying issue?

@xfirstxlast6502 Год назад

Ignorance is bliss?

@PumpUptheJam81 Год назад

It has been a while since I have watched the Munroe tear down of the Rivian packs, but if I recall correctly it does not have the cooling capacity that we are used to with Tesla products which were initially the industry benchmark. The battery cells do not have as much surface area exposed to the coolant vs tesla. It would be interesting to see how much more they can squeeze out of software adjustments.

@justinfowler2857 Год назад

Sounds like Rivian should just set their battery cooling system to start at a certain battery temperature and then just leave it on until the session is complete.

@jacobcarlson4010 Год назад

Yep, most likely a static temperature limit in the BMS firmware. What I don’t get is why the actual **ck they don’t have the master computer (the one behind the screen, managing all the systems) poll the BMS temperature sensors and start to bring the battery cooling online/ramp up BEFORE the thermal limit. It’s not rocket science, FFS.

@rob8969 Год назад

They definitely removed that warning that it was overheating even though it is doing it

@derekmodric2693 Год назад

Yes I can confirm the same on my S, DC fast charged at RAN, then hour and a half later at another RAN (while on road trip) and fans/compressor kicked in on the second RAN but no warning came on, I was quite surprised

@fineartz99 Год назад

Bless you, Kyle, for this intensely detailed exemplification for Rivian Engineers' communicational cooperation to benefit ALL owners, at this latest presentment.

@jwardell Год назад

Haha the unexpected shoutout from Kyle the day after I sell out of parts... Yes, there was a noticeable improvement in the .10 updates, Rivian is now running the compressor much harder to keep the pack cooler earlier in the curve. It used to charge and heat up quickly til 52C and then fall off the cliff crashing down to about 70kW. The earlier update helped a little bit but the compressor didn't run much. Now you will feel the compressor running full tilt well before the pack hits 50, and never actually lets the max temp hit that limit and fall off the cliff. Derating to 100kW or so is much better than before.

@jwardell Год назад

I should add unfortunately, EA has eliminated all stalls over 150 in New England so I can’t quite duplicate the previous cliff log data, but the pack would clearly heat straight to 122F then derate and slowly ramp cooling, and now it cranks cooling early so it never climbs above 118F. Also folks don’t seem to realize it takes a half hour or more of driving not only heat a cold pack, but to cool it back down after a charge. This is why I stare at my temp gauges all the time :)

@zollotech Год назад

I charged the other day in my Rivian from about 10% then to 100% in Atlanta and it slowed some at 50%, but not like yours. I saw the drop off closer to 60% or so. It was at Porsche Atlanta Perimeter and it stayed at 200Kw surprisingly long. Also mine is from this past December so it’s possibly an internal improvement?

@jchoosier15 Год назад

I’m a new R1S owner, my understanding of charging is definitely pretty small, but I just did a 2000 mile road trip and in general I felt like I would stay at 200-220kw up until 80%, I didn’t notice any dips but definitely hear the fan going. That’s around 500-550mph.

@connor84128able 11 месяцев назад

What’s it vin?

@j4k3br4k3 Год назад

I had similar charging this week. Dropped off like a rock after 40% down to 100kW then gradually ramped up again to 150ish then finally back down again with higher SOC.

@voodoo-rides Год назад

Kyle call sandy Munro they noticed on a rivian battery tear down the entire battery pack (all cells) do not have cooling coverage. Your hotspot idea is probably exactly what's going on this could be easily be validated with a thermal imager would be a great video too

@user-oo3uj5ku9r Год назад

Nice video Kyle. Thanks for all you do.

@omelborpon3159 Год назад

Maybe not a successful test, but this is still more data. We do owe thanks to Kyle for all the time he has spent accumulating data and passing it along to engineers and users.

@azorglub Год назад

I have done a handful of fast charges over the winter in my R1T, and have not seen this behavior. I usually plug in around high 20s to low 30% and I think I got around 180KW around 50% and then slow taper after that but no drop off. Truck purchased November 2022. Will need to do more

@mattjohnson5179 Год назад

I just got my R1T about two weeks ago - DCFC'd for the first time the other day and right around 40% it dropped down to 100kw and kept at that until 70%soc.

@johntrussell7228 Год назад

So it's still overheating the pack, it's just not telling you now? lol

@alzamboti8639 Год назад

Great video's, question on Rivian bi-directional charging future? I would buy the R1T for sure knowing if this V2H is possible in near future with Autel or Enphase upcoming chargers!! Any update/status on this? Thank you

@jjmarogil 5 месяцев назад

Do you have a video explaining how rivian uses the motors to heat the battery in the winter ?

@FZ6Dude Год назад

Kyle, I’d really enjoy seeing you do this same test on a 150-180Kw charger to compare the curve difference. On my newer R1T I’ve seen what you are seeing on the 350 chargers it holds over 200kw for a period then drops and slowly ramps back up. But I’m not seeing a second drop until after 65%. Yet on my last few sessions I’ve used the 150 EA units and seeing a constant 145-160kw without any derating and it holds steady throughout the charge until reaching the same 65% area where the battery seems to slow charging. Please do a comparison test if there are chargers available! My truck is still >5k miles with mixed dcfc…

@estan1965 Год назад

I’m really surprised you don’t have an OBD2 reader to monitor the battery temperature.

@jacobcarlson4010 Год назад

To be fair, the really good ones that are likely able to poll that info from the BMS are usually over $600, so not exactly a trivial spend. And even at that price, there’s no guarantee that it would have the software to read BMS data.

I love my Audi etron but hate it's range. I am currently considering the Rivian R1S....however....the one thing I love about the Audi, it's it's constant fast charging reliably. I've driven all over the country, from coast to coast (and into Canada) several times a year, and it has never not charged fast. This issue wjth the Rivian gives me pause

@Tactical_Assault_Pelican Год назад

Im hoping they fix the hardware for the battery pack, bring back quad motor+max pack and fix the taunau cover, the 3 things I need from rivian before I buy my R1T

@johnpoldo8817 Год назад

Kyle, do you think the engineers placated you by removing “battery too hot” message so now all you see is a lower charge rate? Or maybe they did make a small improvement and I removed message so you feel a little better. Did you consult Tom before his Rivian was sold to a friend?

@@jacobcarlson4010 Coolent pump should be running if it's actively cooling the battery.

@brady783 Год назад

I can only speak to personal experience in my R1T, but I don't see this behavior. At about 50% SOC, I see the rate walk down to about 135-140kw, with battery cooling running loud. It stays there until 66%, then walks down to about 110kw. It takes the final dip at 73% to 90kw. I rarely charge beyond this point. Fans always running hard after unplugging.

@Mr.Ro8ot Год назад

You should get your story straight you said in the beginning you were preconditioning the battery and then when you went to charge you said that you didn’t preconditioned the battery, so which one is it?

@captainron7904 Год назад

The only problem I have with the Rivian is the price for a moderately spec one you pushing $90k. That and one more Rivian still does not have any service in Hawaii

@lifeaccordingtobri Год назад

Sounds like Rivian's system is chasing it's thermal loads instead of anticipating and compensating as needed. My $.02

@xfirstxlast6502 Год назад

So they don't want you to know how it is working, Probably not good. LOL. Wonder if they have slipstreams newer vichecles with better cooling capacity or even just a better design of battery pack? One reason one might want to hide things just a tad. If you could see details, it would be pretty easy to infer from data any battery changes.

@Gary_Walker90 Год назад

Kyle, if you had a choice of your Rivian or Taycan Turbo or Turbo S what would you choose? I’m so torn.

@GregMcNamer Год назад

What? They have COMPLETELY different purposes and feelings. Taycan is a very good sports sedan and road trip monster. The R1T is a capable pickup truck that actually drives pretty nice. You'll spend 1/3 as much time charging with the Taycan on a road trip.

@TheAndrwwJohnson Год назад

You can get a Rivian and model 3 for turbo S money. Wtf are you comparing?

@davidmenasco5743 Год назад

It's a kind of religion. ICE vs EVs has become our century's Catholic vs Protestant. Strongly held beliefs on both sides. I guess the difference is that there is evidence to draw upon in choosing a drive train. But if you study epistemology, or even just communications, you know that "evidence" and "facts" can be a slippery subject. Another difference is all the secret preaching done by big oil through their surreptitious campaigns of influence.

@timgurr1876 Год назад

Thanks for video. Glad I did not buy a Rivian R1T, too many startup issues. In general, time for charging batteries is the biggest drawback of EV’s. The other thing is that mining and processing EV battery materials is releasing CO2 into the atmosphere and one video I saw estimates that one typically needs to drive 60K miles to reach the breakeven point. Definitely needs to be better battery technology to increase kWh density and charging cycles. Also, need to move away from relying on China battery manufacturers.

@reviewsandprojects Год назад

@Michael-db4sn Год назад

One wonders what battery life of these vehicles is in terms of battery degradation with the charging and heating issues. I hope in 10 years you can still pull 90% of the battery's original charge out of it given the price of the vehicle.

@ultrastoat3298 Год назад

How is Rivian this bad at something so critical to the experience of owning this truck?

@Paul-cj1wb Год назад

Its not an 800V system. The pack is going to get much hotter due the higher amperage required to get those faster charging speeds, rather than higher voltage, so the cooling system has to work that much harder and earlier. All large battery EVs need to be 800V or higher architecture. It's so much easier to keep the pack cooler is such systems due to only a quarter of the heat generated -- Ohms law. It's why the Taycan charges so much better and at much higher speeds. It's night and day when compared. But it's early. They're learning. The gen are going to be 800V systems.
