The truck is currently in for service and this is one of the issues on the ticket. We'll see if the SC can replicate it.

When my truck is plugged in the L2 charger, it should pull power from the charger automatically when I use climate controls to maintain range set and warm-up the battery pack. Now you need to use pre-programmed schedule to achieve that which is useless if you have a variable time of departure… and you burn more than 10% of range in the first 10 miles with a cold battery. Why wouldn’t anyone want to pull power to do that if you are already plugged in ?

Even the scheduled version doesn't pull shore power immediately. It seems like they wait until the SoC drops below your set charge limit before they pull shore power...just silly.

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

I just want separate controls for the front defroster and the heated wiper park. It’s brutal running the defroster while in a snowstorm just so my wipers aren’t getting ripped to shreds when I go to clear road spray from the windshield
TIL we have a heated wiper park? Is it an electrically heated one like the rear defrost or just a vent that blows hot air?

Mine did the same thing. The SC had to do a hard reset of the whole truck by unplugging the 12V battery (I think?) for 12 hours or something like that. Apparently there were a few modules that weren't waking from sleep so they forced everything to sleep and wake up. It has been fine ever since.

Might be something to tell them about if you can.

The heater doesn't run on AC power so it cannot pull from "shore power" as that is supplied in AC form. The best you can do is pull from the DC battery and replenish from the wall which is what it should do...or at least that's what mine does in the exact way you described, wait for charge to drop and kick on after that.

Obviously...but prior EVs I've owned will pull the same power from the wall that the heater is using so there's no net use from the battery, assuming the EVSE can keep up. In other words, if the vehicle knows the heater is using 5 kW, then pull 5 kW from the wall while it's running and follow it down...if it drops to 3 kW, pull 3 kW from the wall. The whole point of allowing it to use shore power is so I don't reduce the battery SoC while preconditioning, assuming I actually want/need the extra range when I leave. I had this in my MINI and my Spark EV, it's not that difficult. I know for a fact Rivian isn't doing this as my EVSE turns blue when it's actively charging and that's rarely the case while it's doing scheduled preconditioning.

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.

Do you have time of day charging enabled? You might be out of your scheduled window when trying to warm the truck up which is telling the truck/charger to not replenish the battery.

I don't schedule departure because I don't always leave at the same time, I just turn the truck on when I wake up and start getting ready. During this time, it's heating the cabin and the seats/wheel. By the time I get in, the truck is warm and I have the desired percentage of the battery available to me. I also know that it's charging because the light bars are green and the Rivian wall charger is also green indicating that it's sending power over. I do this while within the time of day charging window so it knows that it's ok to pull more power.

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.
I agree that you shouldn't have to warm the pack only via pre-programmed schedule. Teslas do not pull from the wall to precondition, they definitely also pull from the main battery pack and replenish from the wall. They have to do that because even their heater is not AC powered.

My 2021 Model 3 definitely did not pull from the wall to warm the pack, it used the HV pack to do it and replenish from the wall. I know this because I charged with a 20A charger and it was super slow, couldn't keep up with the warming action.

I do, but it's well within the window. Our ToU rates are only expensive from 1p-7p, so I usually allow charging from 2a-12p next day, and I really only set it to start so late so that charging finishes closer to my departure time to keep the battery warmer in the winter.

It's interesting that yours works different than mine then, maybe it's because yours finishes charging about the time you want to kick on the heater so there's no recovery time? Or what amperage do you have to your wall charger?

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 the morning with a cold battery (Tesla is not doing that, as a matter of fact it actually shows a lower range because the pack is cold) and defrosting/heating won’t be enough to bring it down to my range set of 80% so it starts to charge. When I leave home at 80% with a cold battery, the first 10% of range will be burned very quickly as the truck is warming the pack while driving.

Sometimes they have a unified software image, with both Gen1 and Gen2 using the same version. Though the two beta testers on ElectraFi who have installed 2024.51.1 are both Gen1 R1T.
