  1. California Dune Color - real life photos (R1S & R1T)

    Looks way better on the T than the S to me for some reason.
  2. Range to zero

    Have an old Model S and this is definitely the case. There’s a buffer built in, but it’s hidden from the user specifically to protect against running out early in case the BMS is slightly optimistic. Most times you can drive to 0 or beyond (I’ve gone past 0 by 11 miles before), and the buffer...
  3. SoonishEV: TopoCharge Wireless Phone Charger for Gen2 Rivian Vehicles

    Just finished installing mine...it's awesome, and the install was as shown in the video. I now understand why the original wireless charger has to stay in. Very odd 3 pin contact built into the charger to power the NFC reader that sits on top. My only additional tip is to be very careful...
  4. Gen 1 Battery Discharge update for 2024.47.01 and 2024.51.01

    We could go the brute force manual check method several times a day. None of us have lives anyway.
  5. Gen 1 Battery Discharge update for 2024.47.01 and 2024.51.01

    My initial glances after the .47 (and .51) update were presuming that total capacity was related to battery temp. But perhaps not; or perhaps there are multiple factors including temp, time since last charge, etc. Though charging likely brings the temp up, but at the same time the gradual rise...
  6. Gen 1 Battery Discharge update for 2024.47.01 and 2024.51.01

    Noticed the same change with .47 and beyond. Definitely battery temp related as I notice a pretty big difference here in OH with the car sitting outside in -5 to 15 degree weather vs in our garage at about 50 degrees. Gen 2 DM Max with capacity as high as 139-140kwh and as low as 134-135kwh per...
  7. Effect of temperature on battery capacity

    The odd thing is rivians method in the cold (per my electrafi data) is to reduce the total kWh capacity and not the available capacity based on temp. This increases percentage charge to maintain a steady range estimate and is misleading.
  8. SoonishEV: TopoCharge Wireless Phone Charger for Gen2 Rivian Vehicles

    Call me crazy, but I think it looks awesome with the residue still in all the topo grooves. Would you ship it like that if requested?
  9. Recommended 10-50R to NEMA 14-50R adapter

    Have the same adapter for an old dryer plug at a family cabin. Works great. I have to turn the amp draw down on the vehicle as the whole garage circuit it’s on will blow at anything over 20 amps or so when the garage fridge kicks on. Agree with being mindful of your draw and knowing the wiring...
  10. Miles at 70% charge dropped with new update.

    had the car in for service for some other things and asked them to assess. “Nothing wrong” per their review. Maybe will need more charges to calibrate, but electrafi now saying 137kwh total available and range at 100% (extrapolated) 414–>403–>396mi as of today. will ctm and report back.
  11. Miles at 70% charge dropped with new update.

    Gen 2 DM Max. Also lost 10 miles rated range. Went from 414 to 403 at 100% (extrapolated from 70% using Electrafi). Electrafi seems to be reporting a lower battery capacity at 140.2kwh, though I don’t remember that number previously.
  12. L1 charging a cold-soaked battery - bad idea?

    Did it visiting family in Michigan last weekend. Very cold and car was parked outside. The battery was definitely cold soaked when I plugged in because we got in late at night, parked in their driveway, and I didn't plug in until the next day. Still easily gained throughout a couple days of...
  13. Rivian 2024.43 OTA update coming this week with new features, fixes, improvements, owl hoot lock sound

    Got the update this evening. No C+, so lord knows their system for rolling this out. I used to be 1-2 days after release while on the C+ trial and now I’m 4-5 after it seems. No huge deal to me, but I’m on the same pace as many with C+, so I’m not convinced subscribers are consistently getting...
  14. Out of Spec 10% Challenge of Gen2 R1T dual Max: Massively Negative!

    I think I this is certainly possible. Battery longevity and range loss over time will probably dictate that. Unclear if they are being very conservative or not, but range loss seems pretty minimal for most owners. Tesla of course got in trouble for raising and lowering this with various updates...
  15. Rivian 2024.43 OTA update coming this week with new features, fixes, improvements, owl hoot lock sound

    Only about 50 G2 on Electrafi. I’m one of them. No C+, no .43 update yet. Hoping for before our thanksgiving road trip. Family member with a G2 and C+ got .43 installed while it was at the service center, but they haven’t picked the vehicle back up yet. Not sure if it was C+ or the service...
  16. Efficiency Questions M/KWH

    371 now. I built this before the tri was rolling off the line and it was likely estimated by Rivian.
  17. Efficiency Questions M/KWH

    Reference chart I made for efficiency of Gen 1 and 2. All Gen 2 EPA range numbers are very optimistic, the large pack most egregiously so:
  18. Out of Spec 10% Challenge of Gen2 R1T dual Max: Massively Negative!

    I regularly see 200-220kw on my Gen 2 Max. On RAN, EA, and Tesla chargers. It doesn’t hold that peak super long, but it holds >150kw well. You want bad, come try my 2015 Model S (especially before the HV battery got replaced). Everything’s relative. I’ve been plenty impressed by Rivian charging...
