Battery Range Loss (Vampire Drain) in Garage

[MainLineRiv]

Hello, perhaps others have posted about potential solutions to your question.
May I ask why you have Gear Guard on? Do you need it in your garage?
Gear guard is an energy hog (same with my Teslas).
My garage environment is very similar to yours. It's been in the 20s and 30s; the temperature inside my garage is 47 right now (have heat in it turned off). My R1S is sitting unused in my garage and will remain so for a long while.

This is what i have done to my R1S while it sits in my garage:
Went into settings, camp mode, selected turn off power, then locked the vehicle. I unlock it with my phone if I need to. Bluetooth and app are active during the say (I shut off my phone overnight). Gear guard has never been on in my garage.

Daily energy losses I see are as follows: checked every AM and compared to previous day AM
12/5: -3 miles, -1%
12/6: 0 miles 0%
12/7: -7 miles -3%
12/8: -4 miles -1%
12/9: -4 miles -1%
12/10: -4 miles -1%

If only I could find a way to permanently disable the Rivian app on my cell. No matter what I do, it turns itself back on.

no, I don’t need it On at home, although it’s nice to have on at my work parking lot. I’ll see if I can figure out how to turn it off at home per the comment above. Appreciate the camp mode, plus shipping mode that others have mentioned

I meant Gear Guard off at home only, on whenever out and about. Apologies for not being clear.
It's in the settings somewhere, cannot recall where exactly.

Shipping mode? Hmm. May look into that as well.

I charge my R1T to 80% or ~ 280 mile range. I normally get about 200-210 actual mile range out of a charge. I charge it about every two weeks. Pretty significant drain. Gear guard is turned off. So I seem to loose about 2% a day it seems.

1-2% loss per day is pretty much "normal" for a R1 vehicle. You can experiment with turning off GG, WiFi, BT, going in to Shipping mode, Camping mode, etc.. but in the end, you'll still likely be within the 1-2% loss/day territory.

I was out of town for 2 weeks over Thanksgiving. My Gen 1 R1T and R1S were parked and plugged in side by side in my carport in Phoenix (mild weather this time of year) and SOC set to 70%.

Energy usage was identical in the cars @ 1.62 kWh added per day to maintain the charge level. That’s a pretty reasonable estimate of the vampire drain while plugged in.

1.62 kWh/131 kWh usable (although this has to be somewhat less now given the vehicles’s ages) = approximately 1.23% loss per day.

I wish this were better. Between both cars I needed 48.6 kWH to maintain the charge levels while sitting idle for 2 weeks. That’s stupid and wasteful but I don’t believe it’s going to get much better at this point with the gen 1 architecture.

If you want to avoid the truck to detect your phone, you can always disable Bluetooth access FOR THE APP (not sure iPhone instructions but in android is as easy as disabling NEARBY DEVICES permission within the app properties)

I experimented with that to monitor VD for a while. FYI, left 10 days for Thanksgiving and lost 8% SoC.

I have to imagine it’s the original 12V battery since it’s less than 18 months old, and I’m checking the threads. I did make Rivian aware of this today, and noticed the sleep icon on the app a lot more since.

I'm not sure what it is about the 12v batteries that Rivian uses, but it looks like they are not very durable.

My R1T was delivered in June of this year and when I brought it to the Service Center to have the powered tonneau cover installed last month, the 12v battery was replaced. Service said that their diagnostics indicated that it was failing, and since we are now in the cold weather months, they replaced it as a preventative measure. It's interesting that there were no warnings indicating any issues with the battery on the truck's display at any point.

I'm grateful to have a new battery at Rivian's expense, but if the performance of the replacement is identical to the original, that's not good: having to get a new 12v battery every six months is insanity. Hopefully, Rivian either switched suppliers, or has managed to get a better quality product from the existing supplier.

One other interesting thing is that my vampire drain seems to have stabilized at an acceptable level. Prior to the last software update, I was regularly seeing drain as much as 4% per day, occasionally even more. At 4%, that's 5.2 kWh of wasted energy each day given the Large battery pack's effective capacity of 131 kWh. The drain seemed to have gone down with the last update, and now with the new battery in place, is only about 1% per day. I'm happy to live with that!

Yeah, I appear to be at 1% overnight with GG off at night. While on this topic, I see people quoting 280 miles of range on 80% charge. I have the 2023 Large battery and it shows 235 miles at 80% in all-purpose mode and 255 in Conserve mode. Does this sound low?

Rivian says that the effective capacity of the earlier generation Large (135 kWh) battery pack is 131 kWh. 80% of that is 104.8 kWh. If you can travel 235 miles using 104.8 kWh, your efficiency is about 2.24 miles per kWh (235/104.8). At 255 miles, it is 2.43 mi/kWh. Both are decent IMO, and not much different that what I see with my PDM Large R1T.

Of course, that assumes that you take the battery to a zero per cent state of charge, something you would never want to do. You can do the math, but leaving yourself a 15% or so reserve, I'd guess will reduce the max range by somewhere in the neighborhood of 50 miles.
