Gen2 Dual Max Nov Build R1T - 800mile in one-day - Fast charging data

[phaduman]

I was happy with the charging speeds I got at all the fast charging locations in that one day when I went San Jose to LA and returned the same day.

R1T Gen2 Dual Max Nov built (delivery in Dec). System version: 2024.51.31.
Temp was nice 50-75deg throughout the day.

1. Rivian Buttonwillow at 10.45AM: 102kWh in 38mins. Avg: 161kW. Saw high of 202kW.
2. Tesla Pomona at 1.45PM: 65kWh in 23min. Avg: 169kW. Saw high of 205kW.
3. Tesla Arvin at 6.56PM: 22kWh in 7min: Avg: 188kW.
4. Rivian Buttonwillow at 7.41PM: 93kWh in 34min: Avg: 164kW.
5. Rivian Firebaugh at 7.49PM: 65kWh in 23min: Avg: 169kW.

Sorry I didn't take note of what my initial SoC was when I started charging but I tend to drive until it was between 10 and 20%, so all my charges started while in that range. It was a Monday, and none of the charging stations (Tesla or Rivian) were more than 20% full.

Was carrying hitch carrier with motorcycle, so my avg consumption was 2miles/kwh, hence had to stop more often for charging. All my charging stops were pre-scheduled by navigation so Rivian had plenty of time to warm up the battery. The battery was slowly warming up - from low 60s to mid 90s when I got to charging. By the time charging was done, battery temp was close to 120F, and steadily declined as I was driving away.

Overall, quite happy (relieved to be honest) with my charging speeds. I had one Gen2 Dual Max R1T owner from Oakland charging with me at same time in Buttonwillow Rivian in the morning, similar pre-condition time, had fluctuating charge rate (dropping from 130kW down to 100kW before picking up to 160kW ish). He said he never saw 199kW rate, ever. His was a September build Gen2. My truck was able to sustain 190+kW rate until into 65-70% SoC, then dropping to ~145kW and then to 120kW rates close to 75-80% rate when I disconnect and drive - as by then, I am done with my restroom & snack/lunch/dinner break.

I have the same - G2 R1s DM; early build of September. My numbers are also close. I travelled 815 miles last week, and my stats are: (all Tesla Superchargers)
*16.4% - 89.4% in 51 mins - max 205 kW; avg 125 kW. That doesn't match, because it required a deep charge for a long stretch.
*13.6% - 65% in 29 mins - max 206 kW; avg 161 kW.
*22% - 60% in 16 mins - max 209 kW; avg 185 kW.

I'm really happy with the current charge curves. Coming from a Tesla, charges are a few mins longer because of being less efficient and larger batteries, but very acceptable.
