Standby test for parasitic loss while R1T unused and unplugged

[Jiri]

Hey all. So keeping myself honest. And letting you know about a fun little experiment.
Sidebar: 600 miles put on the truck last few days. And I truly feel so far it’s the best vehicle I have owned. And sadly, or fortunate to do so, have been able to own quite a few. (Sport sedans, Defenders, Land Rover LR4s, Land Cruiser, G wagon etc.)

anyway … since I am traveling for a few days, I intentionally left the truck outside in DC to test parasite drain. Not plugged in, of course. This is the app reading for the battery when I left it. Temps in 50s day time and 30s and 40s night time. Rain next two days. Gear guard on. Snapshot at departure and second snapshot after 36 hour (night time - reason I say that is that it does creep up a few miles when it warms back up daytime).

I will post more updates here every day for next couple of days. Departure shot was 13:00 on a sunny day about 55-60 degrees and shot after the truck ran for about 25 miles.

departure:

After 36 hours of the truck sitting during second night, just under 50 degrees early evening:

Thanks for doing this test. I Can't wait for your final results.

Hopefully Rivian is tracking/investigating this (potential) issue as well.

Following, love the test!

48 hours later. Second morning. 49 degrees Fahrenheit. (Gearguard on).

Really concerning...doesn't happen in my Chevy Bolt EV.

Doesn’t worry me too much yet. And likely just needs some optimization on what’s running in the background. I am going to do this again in a week or two after I get home with gearguard off. Maybe those sensors and cameras drain good bit.

I'm new to this, so forgive me, but how is it "bad" to use 6% battery in 2 days time, in cooler temps, with 24/7 video monitoring on? That seems reasonable to me. I mean the truck is off, but it's not sleeping. Other than geeking out over conserving every SOC %, I don't see a problem with the result.

Kudos for the test.

Yes, thank you for the test information. We all need to know these things.

Just remember, 6% is 8 kWh. That's not a small amount. Posted elsewhere, but my MINI sat at the airport for a hair over 3 days and used 1% of a 32.6 kWh pack, or 0.3 kWh. Obviously it wasn't doing video surveillance, but 6% is excessive for 2 days.

Agree. From what I remember, and its been a while, Sentry mode uses about 5% on average per day when its active. Obviously quite a few variables in that but that was the baseline I recall. And this assumes its not being triggered constantly. I'm sure more optimization needs to be done but I'd assume Gear Guard would be about the same.

My Tesla doesn't have Sentry mode, but a quick google search says that it uses about 6-7% of battery a day when left on and parked (a little over 5kWh per day). So this seems to be within the same range minus some optimization.

Ok, fair. By the same token, wouldn't BMS take more energy to maintain a bigger battery too? Not being argumentative - I'm genuinely asking. What is reasonable to expect, that makes this performance excessive?

I realize efficiency is a priority and I guess this sounds inefficient compared to some other vehicles, but I'm having trouble making the leap to it being worrisome. If it's using ~ 3% per day, even starting with 68% would give 3 weeks of unplugged storage before the truck is dead, everything being equal.

Yeah, this 100%. 8kWh over 48 hours is a 166W drain.

This isn’t much worse than what I was getting sitting in my garage over a 31 hour test I posted on another thread the other day (~150W). With PAAK off to avoid waking my truck many times during the day I was still getting ~100W of average draw. At the same time my EV6 has been sitting for nearly a week now and I have loss <1kWh of battery.

I presume your Bolt isn't operating a camera security system. Tesla Sentry drains the battery too

 

[AdamsFan1983]

Any chance the telemetry uploads Rivian pulls are involved in the level of drain as well? Maybe?
