Employees on the assembly line are moving toward the Model Y line as they are slowing the pace of the CT production according to Electrek… look at these parts that are simply glued. https://www.facebook.com/reel/2011003139309083?fs=e&s=TIeQ9V&fs=e&fs=e

…and transmission gear, oil pressure and température. ? My point in all this words salad is that when I have a longer trip and my truck is fully charged at 100% with a 465km estimated range, I would like to be able to use this range and not spend 10-15% of it to warm the pack Which could be...

That doesn’t make sense as you will spend it anyway in the first 10 miles while 10-15% of range is burned to warm the pack.

Only if the cabin heating brings the range below your target and then start to charge the pack. The trigger to warm the pack is not the scheduled pre condition of the cabin but the request to stay at your target range. This doesn’t work for me as a warm pack at 80% after evening charge will show...

Anytime from any range level it will warm the pack before charging at max power.

If you charge just before leaving the pack will be warmed-up to 30F… but it won’t by just conditioning the cabin. That’s why my work around is to increase the range set higher than my usual 80% to force charging when I heat the cabin before leaving for longer trips.

Do you use high regen ?

No true at least in my 2024 Quad R1T. It does warm the pack to 30F while driving and that is why range usage is abnormally high in the first few miles. Same trip, same conditions and range usage is much better after the first 10 miles when the pack is warmed-up. It doesn’t warm the pack above...

Doesn’t matter to me if I lose 10-15% of range in the first 10 miles because of inefficiency due to cold pack or because of energy being used to warm-up the pack. If I could leave home with a pack at 50F I wouldn’t lose that range for no good reason. It‘s a simple fix to heat the pack using...

Manual DC fast charge preconditioning is not the right answer to this issue as it will warm-up the pack to 85F. Cabin preconditioning should use the charger if plugged in to warm the pack to 50F for normal driving with full range available for that purpose.

Which doesn’t make sense. It should warm-up the pack automatically when pre-conditioning the cabin if the car in plugged-in as my 4 years old Model Y does not matter what is the range set.

It will warm-up the pack only if the preconditioning of the cabin brings your range below the range set and consequently start to charge. Tesla does precondition the pack automatically and Rivian should too.

…at the expense of range. They need to implement an option to warm-up to 50F when plug-in while heating the cabin. Otherwise you can’t use the full range for longer drives.

I don’t think anyone here has to back up everything with detailed data… I’m not trying to win an argument. I am just sharing my own experience living in a cold country in the winter. My Gen 1 Quad R1T WILL lose 10-15% of range in the first 10 miles when I leave home with a battery at 20 degrees...

It doesn’t matter if HVAC use the pack as a power source instead of the charger… it should pull from the wall to warm-up the battery pack if it is below 50 degrees otherwise your SoC is overestimated by 10-15%. I guess not many Rivian developers live up north.

The problem is unless the car pulls power from the charger, it will NOT warm-up the battery pack while heating the cabin and you range will actually be at least 10-15% less than is shows because the system will use it to warm-up the pack while driving.

It’s actually worst than that. Not only it won’t use the charger unless SoC goes below the range set but it won’t warm the battery pack unless it start to charge to a higher SoC. Tesla does a much better job at managing the pack temperature and shows on the App when it also precondition it.

That’s what I meant (Sorry English is not my first language). Either way it does pull from the wall as it replenish which my R1T won’t do unless I increase manually the range set to force charging and battery pack warming up. SoC at 80% before going to sleep will most of the time be at 83% in...

First, it shouldn't have to be done thru pre-programmed schedule only and second, it could pull from the wall to warm-up the DC battery pack no matter what is the SoC. That's what my 4 years old Model Y does.

True and it should to at least warm-up the battery pack even if range is over the set target.
