Any tests done on Vampire battery drain?

[jjswan33]

Most recent experience:

I unplugged 4/3 at 7am and didn’t drive all day Sunday, 24 hours later I went from 70% SOC (191mi) to 68% SOC (185mi). Parked in the garage.

Gear guard is on but I don’t think it is working, I went out and was rocking the truck back and forth and it didn’t activate. Car definitely woke up (drive me, drive me) every time I walked by with my phone.

Also the other day I noticed a much larger drop during the day. I had left the HVAC on and I assume that every time the car sensed my car key it turned on? Not sure but lost like 5% SOC in less than 24 hours. Ive started turning it off after every drive.

To follow up on my previous comment before I take my R1T out for a drive. Gear Guard is active but not working as far as I can tell, HVAC is off, parked in my garage.

• Pulled my R1T off the charger at 7am Sunday 4/3 at 70% SOC with 191 miles of range
• 24 hours later it was at 68% SOC with 185 miles of range
• As of 4pm I am now (31 hours later) I am at 181 miles and 66% SOC

Assuming 125kWH usable and 271 mile full range estimate means estimation is 2.17 kWh/mile

10 miles of lost range then equates to 4.6kWh of lost battery over 31 hours which in turn translates to 150W of average power consumption while idle. That does seem like a lot to me.

Just for comparisons sake I haven't charged my EV6 since 3/29, also to 70%. It is still at 69% SOC.

For those of you with vampire drain that is high can you test if disabling phone as a key helps? That feature seems to be very sensitive from reports and could cause the problems

So I turned off phone as a key, charged to 70% last night. Took it off the charger at 9pm. As of 3pm today 18 hours later I am down 4 miles of range. Which works out to 1.8kWh (based on my math above) and a average load of about 100W. Better but still seems high.

Tonight I try phone as a key back on but auto lock/unlock off.

Did anyone experiencing drain notice this suspicious individual in the vicinity?

A very interesting real-world test happening here:

Looking like a 3-4% daily drop. Really hoping that Rivian is tracking/investigating this issue.

A friend of a friend works on the Rivian software engineering team. This is was a known issue before they started customer deliveries. I don’t have any read on if it’s correctable or not, but in general I got the sense that the software team is pretty unhappy with the state of what was shipped. This is just one of a number of under the hood issues it seems.

I am wondering if there have been any (comprehensive) testing of vampire battery drain when a Rivian is parked for an expanded period of time (over 2 weeks)?

I am curious about this issue too. I took delivery of my R1T and went on vacation for 8 days and left it unplugged. When I left my range was 150 miles, and when I came back it had decreased all the way down to 28 miles. No gear guard, and no, climate system running as far as I could tell. Anyone else have the same experience?

This is problematic in all sorts of scenarios. Leaving it an airport for a week is inconvenient, but what if you leave it at a trailhead for a week and you are 100 miles from a charger? What started as a comfortable buffer is now lost and you might not make it back.

Not to mention, 4% loss per day is resource wasteful. With all the shortcomings of an ICE, our adventure vehicle sits for weeks at a time consuming nothing. Idling a Rivian pencils out to $355/yr vampire drain (4%/day*365 days*135kwh*.18¢/kWh).

I was disappointed in the daily loss I was seeing and was curious where heat loss was occurring so I used a FLIR scope after the vehicle had been sitting unplugged for about 15 hours with nothing operated in that duration. Gear Guard was set to not be active at home which is the location where I checked it and external temperatures were about 45 degrees. The pictures aren't great because I don't have a phone mountable FLIR device.

Camera area on the mirror and drivers side door handle. All the cameras were showing "warm" to varying degrees.

This is the front windshield which is showing heat coming off the rear view mirror "cluster" and the back of the hood by the windshield.

The rear facing camera above the bed and an area in the lower middle back of the cab exterior.

Back area under the hood.

There was a warm area on the front end including and above the front facing camera. The proximity sensors also showed warm, though I checked a couple times later and one of the times I wasn't seeing heat from them.

Rear proximity sensors.

This was an odd one to me. This is in the bed with the tonneau closed. The warm area is roughly under the passenger side gear tunnel button. The heat was only detectable from inside the bed and not the exterior. Really wonder what is there causing it.

I also looked in the gear tunnel and underneath the R1T. Nothing showed up in the gear tunnel and there was a small amount of heat showing from the recessed bolt holes under the vehicle.

Seems like gear guard isn’t truly turning off. In the first photo I clipped, I suspect the heat is just the 12v batteries discharging due to the power draw of the various other sensors and cameras.

The last one I wonder if might be one of the power outlets in the gear tunnel. There is a 12v on the driver side and 120v on the passenger side, correct?

I wondered why my "trip" was so inefficient and suspected vampire drain was affecting my trip meter, and I was right! Now I'm pretty annoyed. I personally think the parked undriven power use shouldn't be incorporated in trips.

Total Energy loss rounds and was 4kWh, 9 Conserve miles loss.

[EDIT] Gear guard is on but "not at home", garage is 50°F, it wasn't plugged in, and WiFi is off. We also noticed it using 5-8Gb/day and have a monthly data cap so turned off WiFi.

Beginning after my short drive from the ferry yesterday:

24 hours later. I had to put it in drive and move a few feet for it to register and update the trip though:

Did you turn off proximity lock/unlock in the vehicle?

I'll turn gear guard full off and see if the cameras are still actively powered. The 120 V system was off so that shouldn't be drawing any power. Curious if anybody knows what sits in that particular spot.

24 hour test on the latest update (2022.11.2).
Gear guard/HVAC off
R1T in the garage unlocked with a temp around 60F

8:17 PM Starting SOC was 70% 194 miles
6:25 AM SOC was 69% 190 miles
8:04 PM SOC ended at 67% 184 miles

~4.5 kWh lost over 24 hours equates to a constant drain of 150-200W which is basically the same result I got on 2022.7.0.

I'm doing a similar test tonight, and then I'll try "Vehicle Shipping" tomorrow.
