PreHeat the battery during the winter?

[LL75]

As the winter is approaching and it is the frst winter with my R1s. Is there a way to "preheat the battery" before leaving to work? My tesla model 3 has the "Preconditioning Option" setting in the app that I can have the climate and preheat ready by certain time in the morning.
Does warming up the cabin also preheating the battery in the Rivian?

Thanks

Unfortunately no not yet. There are a couple of manual alternatives though that will help you on colder days in the morning.

1. In the morning maybe 15-25 min before you are heading on a trip turn on your cabin temperature and then start battery charging simultaneously. (You may need to increase your max charge 1-3% points).

2. Set in your navigation a DC fast charger probably at least an hour or two away. I’m not 100% sure on this method when your battery is already above a certain % as it is, but I’d assume it should work as that is what I did in my Tesla before it came out with its scheduling function.

Its coming. Maybe Q1.

Thanks. Is rivian battery capable of doing the battery preheat with future software update? Currently, I am turning on the the heat in the cabin about 10 mins before leaving for work. the R1s is plugged in most night and set the charges at 70%. Are you suggesting move it to 71 to 73% when you doing the cabin preheat?

Preconditioning probably not worth the energy spent doing so. The only way i can think of without wasting energy is to either use scheduled charging or set your charge limit 5% lower then go into the app shortly before you leave to top it off.

Otherwise if you have the truck plugged in, it should keep the battery from getting too cold. Are you concerned about something specific or do you just not want it to use energy while your driving?

I get pre-heating the cabin for comfort but is there evidence that pre-heating the battery is better for efficiency than not?

Maybe not proven yet with the Rivian (not sure if anyone has tested), but preconditioning the battery does increase the usable range in other vehicles once you’re actually driving. No reason to believe Rivian would be different. If you absolutely need the maximum range, then yeah, it helps. If you don’t, you’re just wasting energy for no reason.

Since I have my r1s plugged in, I would like it to preheat the battery as much as possible instead of using energy while driving. Also, our electricity is free from 9pm to 7 am and I have to leave work at 6 a.m daily

This is true in my model 3 for sure.

Yes.

Right so for most regular driving pointless but for longer trips helpful.

I'm certainly in over my head here, but my understanding is that one way Rivian heats the battery pack is by inducing the motor temps to elevate, then sending the now warmed glycol from the thermal management system to the chiller (which is now functioning as a heater). This allows it to work as kind of rudimentary heat pump for warming the battery pack. As I understand things, the motor temps are artificially elevated by software manipulation of electrical current or magnetic field (unclear to me which), so the only energy cost is would be a slight decrease in efficiency, making the heating close to free.

As I said, I'm in way over my head here, and am sure I'll be set straight by those who truly understand Rivian thermal management.

Sadly, the R1 doesn't appear to use wall power when doing cabin preconditioning. That's a huge miss for me since that was most of the benefit of cabin preconditioning with my previous EVs. Why hit the battery while plugged it!? As for battery preconditioning, it probably doesn't make much sense for short trips where you don't need a ton of range, but it would be really nice to get this done before heading out on a longer / road trip where that first charge your efficiency will suck until the battery warms up sufficiently.

If this is the case, then I don't see any future update for battery preheat like Tesla.

Actually the opposite. On long trips it takes about 10 min to warm up then you're good.

If all you take is short trips in the winter, and never prewarm the system, your efficiency will suffer.
