R1S Charging speeds and range

[Vladimir123]

Hello I am new here and tried to find the answer but couldnt so forgive me if these have been answered.
I have the Tesla Model X and really thinking about the 2025 R1S dual Max, I hate the Tesla range but the charging speeds are crazy fast. I can go from 20-80% in about 20 minutes.
How long does it take to charge from 20-80% - ive seen youtube videos anywhere from 30-45 minutes. Which is fine if there are any restaurants near the chargers. I find Tesa chargers are usually at gas stations,
Real world numbers how many miles, 75MPH, does the 80%-20 get you? I know there are about 100 variables but just in general, I typically travel 95 FL-MD. The 2 rivian network chargers on 95 are about 230 miles apart.
Do you seem to get better or worse charging speeds or consistency using the Tesla network? Ive seen videos of the Rivian fluxuate between 75-200 KWh using CSS.

Thanks in advance for feedback.

A Model Y will charge much quicker than an R1S dual max because the battery is about half the size. 60-81 kWh vs 141.5 kWh.

We are all mostly using the same chargers since Tesla opened part of their network, so in my experience charging speed won’t vary much.

You’ve got to do some math on the difference in efficiency and range and compare that to the kinds of trips you do to decide if the inconvenience is tolerable.

Thank you -
I am retired so the inconvenience really doesnt bother me. I have a dog that I travel with so thats a 20 minute stop no matter what I drive. My biggest issue with the tesla is that there are a lot of places I just cant go because there are no chargers within range. Im thinking if the Rivian can get a true 330-370 mile range then that opens up a lot of places. If I can find a charger near a restaurant that make it no inconvenience at all.

This is what I am looking at as a base line but I dont know if it is true on my Rivian numbers. Ft Lauderdale - Bowie Md is 4/5 stops in the Model X plus the free destination charger and what I am thinking is that it would be 2 in the Rivian, plus a free destination charger at the hotel.

I think you’re overestimating the real world, usable range. You’d be fast charging about every ~200 miles on a long trip.

141.5 kW battery
2.3 miles/kWh on the highway
using from 80% down to 15% SOC
Equals 212 miles between charging

You could get the Rivian app and test the route planning for the model you’re looking at.

thank you for the App suggestion -

I did this trip and made a video about it. Used Tesla exclusively. It's a game changer. 10-80% under ideal conditions about 35-40 minutes. Tesla as you probably already know is very reliable.

It charges close to Model Y speed wise. Tesla maxes out around 250-260kw and Rivian max is 220kw. As someone else said, it's much larger battery. A 10-80% charge on a max pack vehicle is approximately 100 kwh.

Tesla Y 10-80 is about 56 kwh. So generally speaking twice as long for the rivian maxpack.

Do you have a Model X, or a Model Y? Your post says you have a Model X, but everyone is referencing the Model Y.

The battery in the X is bigger than what is in the Y, but certainly not even close to the size of the battery in the R1S. The comments are all relevant even though referencing the Y, I think.

I have the Model X long Range, the Y long range cant go as far due to the battery size. I was more interested what real world range people get in the R1S Dual motor max pack to see how it compares to my X. The video above was extremely informative, exactly what I was looking for. I cannot make it to any of the places he did and I only do 5 over the limit. I have to stop just below Richmond, then again in Benson, NC and others after that. I am making the trip again in October and going to take notes on how far I can actually make it. The only benefit I see of the X is the car is a beast on the charging, 20-80% in 20 minutes or so

Thank you for the feedback

Excellent video, Ken. How many miles did you go between charging stops?

I noticed that you only charged what was necessary to make it to the next stop. What if you charged more, and picked a stop farther away? Was that an option?

All the SC stations you stopped at were amazingly empty. So different from EA.

I have used the Tesla SC network twice now, and I love it. There is one big issue that bothers me, though: the potential for taking up two charging spaces. I really don't want to be that guy. Luckily both times I used one I didn't need to do that. But one day, it will happen. I really want that A2Z extension cord. Or the Tesla one.

Thank you guys. Yeah I said the model Y. model X comparison will depend on which model X he has the biggest one I think they make is the 100 kwh. Smallest model X battery I believe is the 75. So if one has a model X with the 75 or 85 pack the range is not all that great.

I wanted the quickest possible arrival and typically that's what I aim for so I only charge as much as is needed to get to the next stop unless I'm eating. Many times when we stop to eat the car is charged to the desired amount before we can finish our meal. So in those cases I let it continue to charge.

In this case we did not have a charger at the location and so I charged extra so that I could let it sit overnight without too low a state of charge. I think we arrived with 38%. Typically I plan for a 10% arrival if I have charging at the destination.

One thing to note is our r1s is one of the last gen1 large packs that were produced at the beginning of April 2024. So we have about 131 kwh usable. The new large pack is much less (110ish kwh IIRC).

The max pack has about 142 kwh usable, so the experience should be fairly similar.

Last note is that we were in all-purpose the whole way and the Dual motor will do better with efficiency because it can disconnect the rear drive unit.

I tried to avoid taking up two stalls wherever possible. I suspect eventually most Tesla owners will leave the end stalls open to avoid a non-tesla taking up two spots. I noticed in a lot of places Tesla actually put in a handicap spot on the end and a sign that says use this spot last.

V4 Of course does not have this issue and I suspect eventually they will retrofit many of the NACS sites. Some vendors are also working on extension cables as well including Tesla.

The last thing I'll say is many of the Tesla sites not only are more reliable, but generally there are many more stalls. Most of the sites we stopped at had many stalls that one we stopped at in Brunswick, Georgia. I believe there were 16 or 20 stalls there.

I don't even use EA anymore because the chargers are either broken or there's a line. When I take a road trip I want Tesla, rivian, and as a last resort I'll use evgo. In Florida, the FPL chargers are the lowest cost option and seem to work well also.

I live in the southwest and have found that every Supercharger I have used this summer throttles the charging speed after a. few minutes. They always start at 200kw, but then drop to 110-150kw very quickly. The truck indicates limited by charger. I used a magic dock in the spring, before getting my adapter, and did not see this, but of course it was much cooler then. The adapter does not even feel that hot to the touch.

We have a dual large R1S and were super impressed by the amount of regen we got off it on a long road trip from NJ to Maine a few weeks ago.

We charged up to 95% on pitstops as we were trying to minimize stops and at RAN it took us about 50 minutes to go from 30% to 95% (it got to 80% pretty fast).

As OP suggests, we stopped to eat each time and found we were running back to the car to avoid idle fees rather than killing time each time.

We visited the RAN stations in RI, Kittery and Freeport - each was located next to places to eat, were pristine and worked great.

In addition to the battery size and times to charge comments made by other Adventurer folks, there are two additional things I’d note:

1. Tesla range estimates always have me range anxiety as inevitably, no matter where and how was I was driving, the available destination range would always decrease as I drove. The Rivian battery size and its conservative range estimates virtually entirely rids me of range anxiety. I always get more than expected out of my Rivian as the battery is just so much bigger and it’s just built differently
2. Conserve mode on the Rivian is your friend while highway driving - in practice it can add 20%-30% more range (my estimate from my quad R1S). Definitely great if you want to reduce stops and get the most out of a long road trip.
