Range Loss in Extreme cold temperatures … Great Job, Rivian!

[zymolysis]

Nope, pretty sure I know the difference

I’ve been around here long enough to know that vampire drain has been quite an issue for a while and specially in colder weather.

Good try though, golf clap for you

Except that your original post said, "...my truck’s been parked out in the heavy snow for the past 2 days getting absolutely dumped on. I haven’t seen 1% even of range loss."

To my understanding, that is describing minimal "phantom drain." Perhaps I am misunderstanding the point you are trying to make, but I had the same puzzlement as the other forum member, when I read your post.

I have seen the seatbelt comment before. I am curious why you buckled the belt on an empty seat?

Some people refuse to wear seat belts- they keep them buckled and sit on them when they drive so the sensor thinks they are buckled in and shuts up the warnings. As a rescue truck firefighter I go to quite a few accidents - the people who wear their seat belts survive low to medium speed collisions with airbag rash , cuts and scrapes - they leave in a friends car or an ambulance. Most of the people who don't leave in an ambulance at speed or sometimes a bag.

Sorry for some ignorance here, is pre-heating the same as preconditioning? If it's simply utilizing the climate control on my app then I got it, but if it's something different with the batteries, I would need to be educated on that.

New to EV - How do you do PREHEAT?
Does it mean warm up the cabin? or there is an explicit button that heats up the battery?

Open the app and scroll down to climate, click the fan icon - it will heat up the cab and to an extent the battery. I would love to have a button just for "prepare the battery for travel" if enough of us request it from the guides it may become a feature. While your at it -ask for car play and android outo.

Set the truck for shipping mode (service menu), close the app and resist to urge to frequently check the SOC. I'm parked in NJ for the month and check every few days, Vivian has settled down to 1%/day. But I left the charge cable and a HD 110V extension in the cab in case something weird happens towards the end of the month and I need the inn-keeper to juice it up a little so I can make it across town to the class 3 EA charger when I return.

No. Preheating is cabin temperature only.

Preconditioning of the battery can occur in 2 ways:

In app go to Climate and create a schedule for when you want to leave.

Use the navigation to drive to a Level 3 station.

Calvin, you are breaking my heart with all those snow pictures.

In the south of BC, we got whacked with a warm, very wet atmospheric river a couple of weeks ago. Our snow was blown away. There are some ski hills that have closed and others with really bad conditions.

Enjoy your skiing!

I hope you’re able to get some insane snow here soon!!

i'm so confused. I just picked up my R1T in december, and I'm seeing around 5 miles of loss per day. I saw about 30 miles of loss in a week with the truck parked the whole time. Even as temperatures got warmer the mileage loss keep up. I contacted support and they said it's normal, and that the vehicle has to warm up the battery, even when not in use. But OP posts that their truck is parked in the snow with zero range loss, something doesn't add up.

I honestly have no idea. Gear guard was left on, I don’t keep proximity unlocking on (just because I don’t really like it), but that’s it. I’m sorry you’re experiencing such high vampire drain.

1% per day is unacceptable for a vehicle that is doing nothing and is supposed to be in shipping mode. IMO the vehicle should be totally off, not draining a single kW. Like my Mach-e does even when not in "shipping mode".

I understand things like gear guard may require more power than the 12V can support, so if you have those turned on it may be worth some drain to enable that functionality. But seriously. It should be zero if you have all that turned off. The battery should be used to move the vehicle, not communicate with Rivian about nothing useful, draining 1% or more per day.

Maintaining the battery, or rather 7776 batteries. Hopefully keeping the 12 v batteries topped up. All the lithium batteries I have used lose charge over time. At one time Ford rangers were known for vampire drain which was a problem because they came with a motorcycle sized battery.

It’s all chemistry & physics.
