#Rivian #R1T #Charging
No one else will put this amount of effort into a charging test, so I think I speak for everyone watching this that we appreciate it. Charging is such an important piece of an EV and very few give it enough attention.
Bjorn Nyland does, and has for years, but I do think Kyle also does an excellent job. Most importantly, Kyle technically understands what he speaks of.
@@aussie2uGA This is true, I suppose I’m just talking about US EV journalists.
@@aussie2uGA Yes indeed. There are so many guys out there. But hardly any one can really assess a car like Kyle. While Kyle may favor some aspects he's mostly unbiased which is probably his biggest strength
Kyle, wow, Rivian needs to write you a big check. Seriously, many of us have been asking Rivian for data like this for years to which we get crickets. So huge Thank you! One question…so if and hopefully some day, do you think Pre-conditioning on road trips will somewhat improve charge times? I can’t believe with all the people they have pillaged from Tesla they still don’t have pre-conditioning in the software.
The dog is like "that dude is talking to himself again".
Love the way the dog just fell asleap with the favorite toy between its paws…. Must be a Golden Retreiver.
@@jenswinther8601 lab/golden mix I think
Ellie is an English Crème Golden
@@jenswinther8601 She looks like she had a head transplant.
I really hope Rivian makes the charging curve a bit more aggressive once they have more fleet data.
This truck is actually pretty well made. It is definitely growing on me coming from a Tesla owner
Entertaining and deeply informative as usual, Kyle. Much appreciated!
Thanks Kyle! Great reviews on the R1T.
Kyle, as a battery researcher, I recognize this charge curve as CCCV - constant current/constant voltage. Interestingly, it seems quite simple. Specifically, it looks like the protocol is 450A constant current until you hit ~450V. Then hold at 450V. Of course, if the pack temp exceeds some value, then that will slow down current and siphon power for cooling. In short, it's CCCV 450A, 450V. Not so complicated.
Yup! Totally agree that makes the basis of the charging logic.
Indeed, and unfortunately there is no way for them to increase the charging power above 53%, only if they had cells with lower internal resistance
Only way for them to improve the charge time is if the RAN allows more than 450 A to gain time bellow 53%
Is this a hardware or software limitation?
@@todd5192 hardware, if you battery pack is at full pack voltage at 53% and any state of charge above that, it’s not physically possible to have higher power than it already is.
@@Pedrodemio Why couldn't they push more current above 53%?
Dude!!! Data is awesome! Thanks for getting it!
Love it! Thanks so much for all the 'nerdy' details! Really enjoy all the deep analysis. Keep up the great work!
Love that Ellie gets to come to work too!
Simply stated - Kyle has executed the best vehicle review ever (I have been reading car reviews for 40 years). I have never seen this level of effort. Rivian should just include links to these videos when they deliver the vehicles ;-)
I disagree. It lacks a continuous thread of critical realism. Driving around to heat or cool the battery in mid-charge to help Rivian save its reputation compromises Kyle’s critical credibility.
Being made in America just isn’t enough. It must be good for people’s lives.
Additionally, full disclosure on the battery and buffer sizes are needed so the customer knows what he’s working with.
Has Rivian left any buffer?
The charging curve suggests that it may not have.
This is a new company. It’s got a lot to learn and has been given a reputation already as if it has proven itself long ago.
But it hasn’t.
Any lack of brutal criticism is not helping Rivian.
Why fix a mistake if there’s no punishment?
I cannot believe the comments are mostly about the information and not the dog
thanks a bunch, Kyle. Very informative!
Thanks!
Love the analysis. I disagree that 800V wouldn't help; at the same power delivered you would generate less heat with a potential to deliver much more power to the vehicle. That being said they absolutely need to work on battery thermal management and preconditioning.
Also, tiny tidbit, put your units in the column header!
Overall, super well done, thank you for posting.
In the end, the individual cells are ~3.7V each, 800V vs 400V is just about how many in series vs parallel - so current seen at the cell will be similar in either case.
@@biketrouble higher voltages mean you wouldn't hit the 350A current limit at those stations and also would mean less heat in the wires and charging system. When you're maxed out on current, this is all wasted charging time and additional heat to manage. If the battery cell heating is the limiting factor, then yes, going to higher voltage packs doesn't help.
I was eagerly waiting for this video!
Terrific work. Very useful to everyone who cares & is interested.
And it's great that you conclude with the "bite sized chunk" to take away for those who don't want to digest all the technical detail: charge your truck to 60% and if that's enough to get to the next charger (with a small buffer of say 5%) then unplug and go. If you've got excess juice then just go faster! 🙂
Awesome, love that detailed test. Again love the graphs.
Look at the puppy hugging his toyyyyyy 😍😍😍😍😍
Amazing content! Thanks for what was clearly a ton of work.
Awesome video Kyle! Thanks so much for all the Rivian videos!!!
Kyle, I know this was a bit geeky but thank you for explaining the processes as well as you have done.
Love the pup sleeping with her baby in the back.
Someone needs to charge the golden in the background. Looking so L-A-Z-Y! What a nice pup.
Great info Kyle but your puppy behind you stole the show she loves that toy!
Bravo and thank you for all this data and explanation!! 👏👏👏 For all this work done, liked and subscribed
I bet zero to near 100% will be more common in the R1T because of the huge towing consumption and likely high consumption when there is a bulky load in the bed.
Love the Details. Great info.
Great video. Finally people get a ballpark estimate for how much it will cost to charge. Big batteries will cost a lot when compared Tesla. Also the time it takes to charge the battery is also important as people will need to adjust their life to the time needed to charge. I’m in CA. and pay on average 10 to 12 bucks to charge at home at 19 cents per KWh. I charge on average once a week as I don’t drive a lot. 40 to 60 bucks is up there and if you are doing that twice a week it adds up. Something to really think about.
Thanks. Definitely excited for this.
how have I never seen this video, great information here.
I just plug in when battery is low, but this is allot of cool information!
Well the dog cuddling the stuffed animal distracted me. I couldn't be happier!
So I think it's implied, if not stated, that Rivian (and possibly Hyundai/Kia) have battery cooling issues while charging that will not let them realize their theoretical best charging curves. So my theory is they need larger capacity cooling systems (fan CFM, coolant volume increases). Also, theoretically, a 800V battery could charge at these speeds with less heat generation and thus make their actual charging curves closer to the theoretical max.
This was SO HELPFUL. Thank you
I think the pack voltage should make a lot of difference in how quickly it charges. Assuming that heat and thermal issues are handled fine, the limitation on charging is the amount of current that flows through each cell. If you have more cells in series then for a given cell current you are getting more power stored in the pack.
Kyle - Charging per kWh is definitely the way to go. Some states do not allow the sale of electricity by the kWh unless the seller is an electric utility.
RE odd indicated % charge behavior when unplugging - My observation is that battery capacity is indicated based on battery voltage. When charging is initiated, battery voltage increases some right away. When charging is stopped battery voltage 'settles' rather slowly. So maybe the software has trouble compensating. Or maybe the BMS is counting kWh into the battery to help estimate the state of charge and it lags real time a little for some reason. FWIW I don't recall seeing this on my Teslas.
50% is my lowest daily charging recommendation from Tesla via the app on my 2019 SR+ M3. My battery pack differs from the new cars though, this might've changed recently but 90 is the tipping point where you're getting into travel distances that shouldn't be done regularly.
Not too nerdy and was great information!
I think the Rivian charging time leaves it an impractical car. You need charging at speed to 90% for it to be useful.
Mercedes do this very well. So do Audi.
This will leave this car impractical.
You can’t live in your nerves at 5% state of charge because Rivian messed up.
Will somebody please pet that dog!!!
I've noticed that my Polestar 2 also tends to jump 1% after I unplug it from an EA station. I think it might be the voltage of the battery settling a bit after the charger disconnects
At 13:14, it's pretty funny that on EVgo's charger UI screen, it doesn't have enough space to display 100%. It can only display two digits - up to 99% - before cutting off the numbers. I guess they didn't expect anyone would use their DCFCs to charge to 100%.
28:53 - Hopefully the OBD II port being locked was only in the truck Rivian lent out to you for testing.
I’ve found two ABB cabinets near me that can output 500A to CCS… well, “near” one is 8 minutes away, one is in schroon lake. They seem to be located at Evolve NY charging locations…
Dude here does a really good job. How many weeks to get to Arizona ? so it don't charge good when too hot or too cold ? My kids had a blast with their RC race cars & when those battery's blew talk about fireworks.
considering the incredibly cute good dog in the back, I am a little disappointed that they did not include dog mode. Hopefully it will be included in an update as well.
There kind of is a dog mode. Swipe up on owner app and you can set temp of interior and turn fan on. With a name like “rex” I had to try it on myself for about 15min…
Hey Kyle,
I’m not sure if you guys are done this video already, but have you guys done a charging test using level 2 recharging?
I know this sounds boring, but probably the vast majority of Rivian owners will do most of their charging at home. What is interesting is if you drive your R1 T to your remote cabin then plug it into level two recharging, how long would it take to charge the current large pack but even more interestingly, how long would it take to charge the future max pack?
I’m waiting for a large pack, but I have three friends who are waiting for max packs because their cabin is a long way from home. Once they arrive at their cabins, how quickly could they get mostly or fully charged again for the return trip home without stopping. I think people are going to be shocked by how long it takes to charge both a large pack and especially a max pack using level 2 charging.
Hope to see this test soon or if you could point me to where you have already done this test I would really appreciate it.
Cheers
Adam.
Great info and video. Love your Deep Charging analytics!
I'd like for you guys to start getting ODBII data like Bjorn Nyland does so you can really see battery thermals, power readings, etc.
They tried, Rivian locked it down.
Love this video!
Hey Kyle, I have a short video of a Rivian charging at 175kw at 62% on Large battery in 15° weather at a Electrify America in Bloomington, IL
I was only pulling 78kw in my ID.4.
Could you do a detailed analysis on how this compares to other EVs on the market- Tesla, Polestar etc.?
It seems like the truck doesn't have a good enough thermal management system for charging at high rates. In fact it doesn't even seem to allow the battery to warm up enough while charging either. The whole charging system seems to need improvement
Why do you think it doesn't request the full 500 amps and limits itself to 450amps? Has this been updated in software updates?
Thanks for doing this!!
looks awesome
10-80% (220 miles of range added) = 42 minutes ... It's ok. 42 minutes of charging for every 3 hours 8 minutes of driving. Towing long distances in this thing wouldn't be great. At 50% range reduction, you're looking at 42 minutes of charging for every 1 hour 34 minutes of driving at 70 mph.
It is much more appropriate to drive even 5 MPH slower to drastically increase your range, as the drag at those speeds is exponential.
@@justinstewart3248 Not sure about drastic. 5 mph would likely add about 5% to efficiency. If the trailer doubles air resistance, then you're looking at a 10% improvement. That increases 110 miles of range to 121 miles. At 65 mph, that would take 1 hour and 51 minutes. 17 minutes extra to go 11 more miles.
If you reach the same charger, then you would have to charge a bit longer if you drove faster, but I imagine it's faster to charge energy than to use it.
In practice, it's better to drive faster and get to the charger faster than it is to slow down and go more miles, so long as you can make it to the charging station. It does save a bit of money on charging to slow down though.
@@updlate4756 in practice this is not always true, especially in the cold. I can stay just under 70mph and considerably increase my range and actually get to where I’m going and charge there, or push it to the next stop or, just not become stranded.
@@justinstewart3248 Everything's relative. If you're normally driving 75 mph, then driving 65 mph will give you about 11% more efficiency. Maybe a bit more in an EV since the car will generate less heat and allow the front air vents to stay closed longer.
@@updlate4756 lol no dude, it’s not relative, it’s physics. And drag is increases on an exponential scale the faster you go. Nothing relative about it.
Thanks for the in-depth reviews, mate! I’d sign up for one but pricing is up there! But before all that, need to lobby on making “Selling Organs” legal! Love the channel.. Keep rocking! Cheers!
Hey Kyle, What does all this mean in relation to charging an EV6? I own an EV6 and it is what I would compare it with. I know that the pack is much bigger but will the R1T charge at a pace close to the EV6? I’m anxiously awaiting my R1T delivery window. I love road tripping with the EV6 and hope to have the same experiences with the Riv!
He just explained more reasons I will not go electric. With gasoline I do not need to keep the tank between 30-70% to make the gas tank last.
Hopefully they'll be able to greatly improve the charging curve through software updates.
curious to hear Kyle's take on the max pack. Can't test yet but how would the max pack impact these curves/daily driving.
Great video. Will Rivian temperature control the battery better in the future?
Conditioning is not cell balancing?
Does any electric automobile company make a travel charger? I would like to travel with my camper and when I get to the camp ground charge my vehicle at the camp site.
At home I always charge my bolt to 85%. I only charge past that for road trips and even then I usually don't go past 90-95%. Though I guess my battery health doesn't matter that much now that the recall is gonna replace my battery with a completely new one lol
Great stuff!
Have you ever gone back to the freewire charger in cold weather to see how it delivers?
more nurdy please!
@34:40 charging costs, capacity and tests.
An 800 volt, or higher, architecture designed battery back absolutely will get less hot. Not only during charging but also during discharging. The higher the amperage trying to be forced into them, the hotter they get. Conversely, the higher the voltage, with the larger conductor required for their 800 volts architecture, the lesser the stress that is placed on them during the flow of energy, either in or out.
It's why the 800 volt architecture Porsche Taycan can charge faster, and maintain those higher charging rates for longer, than any current Tesla, and keep doing 0-60 runs over and over and over again, when a Tesla has to stop and wait to cool down after a limited number of runs.
800 volts is harder to design on cylindrical cells, which is part of the reason why Tesla has redesigned it's cell with all those extra little tabs.
I am a pre-order holder for a Max Pack Rivian R1T. Would you expect to see a similar charging curve regardless of battery size?
How long did it take to charge using an extension cord?
Good info but you don't have lunch on the graph. Seems how most people travel, they start early in the morning and drive 300 miles. Say that's 4-5 hours. Plug in and have a leasurely lunch for at least an hour. That would get you over 80 percent or 250 miles. Drive another 4 hours for an 8 to 9 hour day. Stop for dinner and you could make it a 12-13 hour stretch if DC chargers are common to maximize mileage. That could be Los Angeles to Moab. Honestly, no one wants to stop every hundred miles to charge for half an hour.
Let me list a comparison, approximate charge speed between 0 and 80%:
Thats not the top speed and not the lowest, its a approximate average!
Rivian R1T: 30kWh/100km, 120 kW = 400km/hour
Mach-E: 25kWh/100km, 120kW = 480km/hour
Kia EV6: 24kWh/100km, 120kW = 500km/hour
Ioniq5: 24kWh/100km, 120kW = 500km/hour
Model 3, Y: 18kWh/100km, 100 kW = 555km/hour
E-Tron 55: 26kWh/100km, 150kW = 576km/hour
Taycan: 26kWh/100km, 180kW = 692km/hour
Rivian is not "bad" but should get some software updates for more charge speed.
I would like to see 450A @ 450V = 202kW.
How do I know if a charging station (or CHARGER) peaks at 450A without plugging in?
Sorry I have a Tesla so I only plug in at home/work and Superchargers, which do not show the 450A or higher.
What is best app to see charger output? I’ve see mislabeling and looking for best data source/app.
I'm still waiting for the R1T dog video. That one may be the reason to swap to the R1T from the S
I would love your ideas/speculation on the charging curve of the Max vs Large pack. In theory if the charging curve is completely percentage dependent then in theory you should be able to get more kWhr faster right? And over a road trip the larger pack would allow you to charger faster stop less. Your thoughts? Sniff
BTW love your passion and anal retentiveness in your videos. You cover so many interesting ideas. Things we all think about but would never do. It all means everything and nothing at the same time!!! Keep up the good work.
Have you tried the wall charger?
I have, including using a TeslaTap with Tesla destination charger. Works, but much slower, of course.
Just shows how advanced Tesla is for having preconditioning.
Kyle, you can be an engineer if you want. Keep up the correctness and completeness, thank you!
It charges at a really good rate but the battery pack is so large.
Without trying, the f150 hybrid goes 300 miles, for $45 used to be $38 before Putin's war. It also only takes 3min a pump for those miles, compared to how long for the EV. The Ford also costs $30000 less. Lol.
Just watching the dog and it's teddy bear
Electric fail. I saw a Rivian towing test just towing a passenger light duty truck/trailer. Range was about 35 miles.
I am excited for EV future. I stay far away from the EV present. Rivian is an $90K truck that compares to $50K ICE trucks. I won't have 1.5 hours to charge on trips, and, once the government adds road taxes to KW's, then the savings will begin to lessen. I wish the government would have focused on a period of PHEV's for a decade or so to ease us, and the infrastructure, into full EV's.
Do you believe them when they say that they’ll have a peak charging of 300 kW? I find it hard to believe they can do that with the current architecture they have for these R1 vehicles.
They won't. This version of the R1T can't public CCS stations. Kyle asked about allowing charging at 800v via a software update that MotorTrend and CarandDriver stated, but Rivian said that is not the case.

My thought on the electric trucks/cars it’s a good idea, but they run on a battery and yes they last for awhile but batteries deteriorate over time. I know that gas fueled cars have wear and tear as well, but it doesn’t have its fuel source deteriorate that makes you buy a new car and yes I know you lose gas when you drive.
Not great, 57% battery in 30 minutes or 164 miles of HWY range.
Totally fine.
@@brandenflasch how is this fine? This is a lot of added time on a long distance trip. If I need to get an 80-90% charge because I don’t have access to a charger at my destination, I would have to wait almost an hour for that charge.

I prefer gasoline , it pumps a full tank in like 3 minutes no mater what the weather and I can carry a 5 gallon Jerry-can.
The cars need to be higher voltage.
That full luscious head of hair!
After six minutes of information free blabbering I gave up on the video. How in the world can a person speak for so long without actually saying anything and how long would it have gone on if I had kept watching? I am genuinely interested in the charging performance of the Rivian but I will have to find that information someplace else where folks have at least a little respect for my time.
So I would plug into a 150kwh charger, probably better for long term.. Kyle did you try this?
So inefficient , it comes from mains as AC , converted to DC for storage , then converted back to AC for motor. Every conversion is power lost as heat.
The Achilles heel of the Rivian R1T. Such a shame.
Good enough to easily charger hop.
I mean sure, but only if:
1) You find those unicorn 500A chargers
2) Plug and unplug a bunch of times and drive around in circles to cool the battery off.
3) Drive in 35 degree weather
@@andrey_climb_bike_ski or just plug in and leave after half hour
Really for any 2022 model year ev. It just shows how far ahead some are in the ev space. Rivian needs 800v, in house motor&inverters, plus the heat pump tech stat.
The range efficiency on that size of pack is damn impressive though imo. I mean the r1t is an 800+hp awd 4 motor 7100+# truck that some how matches the Audi e tron and jaguar I pace for hwy mpge efficiency. 😁
@@4literv6 not sure why it needs those things when you just said it’s impressive.
