Long term battery vampire drain test (47 days and going)

[Dirty_B]

I wonder how things would improve if you put it into 'camp' mode. I think that's what it's called where it puts more components to sleep to reserve battery SOC.
I'll need to store my (yet to be acquired) R1S for several months after delivery and I've yet to determine the best way to do this. I'm thinking setting it to 70% SOC and pugging it in so it maintains such. Even if it's plugged into a 110 plug this should be fine.
Thoughts are welcome, particularly from anyone who's stored their Rivian for an extended period of time.

Shipping mode not camp mode.

What mode should I set prior to the vehicle sitting for extended time. I just put mine in transportation mode and will be gone for a month, is that necessary or should I just park and lock?

Shipping mode. And charge it up to 70 or 85 prior.

The couple of times I tried it, camp mode didn't make a difference...

I don't put mine in anything special. I hop out, lock it, then close the app - fully close not background close - to ensure PAAK doesn't trigger the truck.

I'm on a 15 day trip, left with 212mi left in conserve. Be curious to see results in two weeks. I'll report back, as the vehicle will not be moved, unlocked, nuttin... Other than maybe me checking SOC via app once or twice. Didn't do anything special, just locked and walked away, no shipping, no camping, no trickle charge...

Please report back. Is that the Buxton lighthouse?

Hey everyone. I had the chance to leave the R1T in the garage for about two months while I'm (still...) out of town training for a new job. I thought this would be a good time to see how long I could leave it unplugged!

Unfortunately I didn't take as much data as all you smarty-pants' probably would have, but there's some interesting baseline numbers to look at here:

Starting charge: 70% (242 miles) on March 5
Average temperature: ~45/50 degrees F (stored in the garage)
Ending charge: 13.6% (47 miles) on April 21

Small disclaimer, only needed to move the truck in and out of the garage to move the garbage bins every week

In total, the truck lasted 47 days without being plugged in. That averages out to 4.14 miles/day or 1.2%/day of idle drain. I guess I could have left it unplugged for another 10 days, but I saw another post on here where it cost someone $1000 to bring their R1T back from the dead.

It was 1200$ for the Rivian tech to come out and replace the two 12v batteries 🪫 that couldn't be recharged once dead for more than acouple hours. Could be a major issue for owners who leave unattended. They need to fix the vampire drain issue soon.

How long was your truck unplugged in "Transportation' mode? Or was it plugged in during transit? What was the charge level when it arrived?

I think I saw a preview of next FW update allowing us to set other max charge values besides fixed 70/85/100% settings. For lithium battery, it's preferred to keep SOC at around 30-40% for long term storage for best longevity.

I wish I had some data to look at on this because it has no reason to heat the battery just on startup. Unless the battery is below it's minimum safe temp I mean.

Well, it doesn’t know why you started it. Maybe you are about to drive cross country. Maybe they could add a “storage” function that would keep it in a low energy state even if you move the truck.

Are you going to keep it plugged in?

Yes, that's the idea, keep it plugged in to offset any drain, but keep battery charge level at that optimum 30-40% level.

My phone has option to cap the charge limit to 85% now, and I wish laptops would offer that option as well (since they're plugged in most of the time anyways).

I've run several 2-4 day tests in "shipping mode" now and my losses pretty much always come out to about 0.55kWh/day.

The OP started with 242 miles and ended with 47.
In shipping mode he would have started with 242 and ended with 190 miles after 47 days.

Good plan but I thought the release notes said variable from 50-100% so can’t do 35%.

Ah got it ,missed that detail, ok 50% will have to do!
