So many variables here impossible to really tell. There is no setting in the vehicle you can change to make this happen. Pre-Conditioing, battery temp, charger etc etc
Charging Limited
At a local 150kw charger I used to pull over 140kw on my R1T, until I hit around 70%, for the last few times I’m now only pulling 74-76 max, no one beside me and my starting percentage is below 20. Anything on the truck I should be looking at to better this? And when someone else hooked up, they were getting over 100kw so make me think it my R1T?

I didn’t precondition as the charging network wasn’t recognized on the R1T. But each time I’ve come off a long 2hr highway drive and plugged in at the end of each journey so the battery should be somewhat conditioned? It just seems odd that it’s exactly 74kw lately is all while others are getting higher rates on the exact same plug in.
I just got my R1S a week or so ago and go to a 150KW charger close to home while waiting for my home charger to get installed. Same issue. It will hit 125-130 for a very short period then settle into 74-75 from anywhere below 50 to 85% can't get it above that so my charging takes much longer than expected or desired.
Took 1 hour yesterday to go from 26%-70% (61 KWH) had to quit to before full because of time constraints. feels like I should have been able to top off in half that time if I would have stayed at the 125KW I peaked at for a short time.
Is there any way to condition the battery other than putting it into the GPS? I know where I'm going seems like a silly requirement

Sounds like you may be using a ChargePoint charger? A typical one is this model: Express: EV Charging Stations | ChargePoint
Although rated at 125kW, that power is shared between two plugs for 62.5kW per plug when two are in use. But even if you're the only one plugged in, they have a second limit of 200 amps, which for 400V charging like in the Rivian results in a maximum power of 200A*400V=80kW. A different brand of vehicle which can do 800V charging can get the full 125kW out of the same charger if plugged in alone.
If you really think it's your vehicle, then eliminate the charger as a factor - visit a high-power L3 charger from a different manufacturer and see if you are still limited. With the 350kW EA stations you should be able to reach almost 220kW when you're below ~40% charge if the station is in good working order.

Thank you. It was an Electrify America 150Kw Charger but it did have 2 plugs. I was the only one using it at the tie and it did reach 125 for a moment and then throttled way back. I am new to all this so trying to learn the best way until my home charger is set up and for a road trip already planned in the near future. Any and all advice is welcomed so I can become proficient at this
Thanks for the reply. It was a Journie charging network at Chevron each time, unfortunately there is not another network near me with those speeds to test your theory. Once I was done I stayed to watch the next person plug in, same plug maybe 5 minutes after me, got upwards of 145kw right away and stayed there. Very odd.Sounds like you may be using a ChargePoint charger? A typical one is this model: Express: EV Charging Stations | ChargePoint
