The importance of that is debatable. Just charge to 80% everyday. Charge to 90 or 100% when needed. The batteries will hold up fine. Some people think L2 departure charging warms the battery for better range, but it really doesn't from my experience in real Winter. Scheduled climate, available in the Rivian phone app, actually will pre-heat the battery from wall power if you want absolute best possible range, but that's probably only completely necessary if you are driving 90-100% of the battery in a day.
It absolutely works. My battery was in the low 50s last night and after charging 27 kWh over about 6 hours (~5 kW) it was at 67F when I left this morning. Obviously less effective if you use less energy in any given day and less effective the longer the delay between charging completion and departure time. You can say whatever you want, but evidence says it is effective and it's super easy to implement...they just keep dragging their feet. Same with cruise resume.

@endress14 ...one example. But also if you need to charge deeper (over 70%) and don't want it to sit at high SoC (90%+) for very long...you can either calculate it yourself and set the schedule, or Rivian could just implement this feature and it would automatically figure it out and finish charging about the time you were scheduled to depart. Makes life easier if people don't want to do the math.

Rivian needs EV ownership to look as simple as possible.
So they make me do math to keep it simple? I hear computers are good at math.

trying to be funny, not argumentative.

A co-op could take the existing scheduling UI and code and make this feature it seems.

Still no option for putting other features on the driver screen. Like odometer, trip gauge (like other cars have had for a generation) and elevation because it helps establishing usage. Must be beyond their programing ability.
We don't know for sure. The actual post on the-site-formerly-known-as-Twitter just says customizable driver display. The person posting it here said 'choose from three'.

Now granted, I can't see the replies to the post so maybe there's more info there...

@elektrode they don't want customers to even be concerned. Why do you need to do any math?

@zefram47 Yes charging is effective at mildly heating the battery, if that is what you mean. But do you know if that temperature difference you had this morning had a significant difference on your range or energy consumption? Rivian knows...they actually only heat the battery to high 50degF in the Winter, when you schedule climate. Possibly because the efficiency difference is minimal past that point. Departure charging might also be effective at saving energy, if that is what you meant, but honestly, I think it is a completely insignificant amount of energy, like less than $5 a year.

take a closer look at the maps in the screenshots. yup, that’s Apple Maps. make of it what you will.

Unless I am mistaken, those wishing Rivian would implement a scheduled departure time, especially in winter, are concerned about issues the linked video below discusses. Not sure how much of these issues apply to Rivian specifically (the impact on region braking for instance apparently does not)

Also, if you are in sunny CA or other parts South, this may not be as much an issue.

Oh, and regarding the virtual Rivian display drivers console, I still get a kick seeing Arjuan display ghost people river dancing around IRL mailboxes and utility posts, showing Semis instead of Tractors, and the ocassional random phantom sideways vehicle rapidly phasing into and out of existence in front of of me.

Speaking of which, would it kill Rivian to post on instagram or Reddit? There are plenty of us who avoid the twixer cesspool when possible.

Just took a close look at those screen shots. Love that center map view and how it flows under the the left panel and fades into the right panel!

I get why you want this, but I also get why Rivian doesn't want to create it. Rivian needs EV ownership to look as simple as possible.

Even though using a scheduled charging completion feature would be optional, the mere existence of it means that Rivian has to explain what it does and why you might want to use it and when an EV skeptic reads that it will make EV ownership seem difficult and confusing.

To 90% of the population, anything related to optimizing battery life or performance is scary. Even the prospect of connecting an electrical cord once a week instead of connecting a gas hose once a week is overwhelming.

Rivian has to carefully balance the desires of power users with the need to convince non-EV owners that owning an EV doesn't require spending as much time thinking about EV ownership as the people on this forum do. If they don't add enough, they will have a hard time selling to us. But if the add too much they will have a hard time selling to anyone else.
Hey are you the same guy that kept Apple from making a two-button mouse forever? ;P

The most optimal battery life is below 55 or 60% which is lower when accounting for buffer. You get significant degradation (almost 2x as much calendar aging) above 70-75%.

Departure charging allows your battery to only hit the maximum SOC right before you leave.

All of my EVs I have ever used are at 50% SOC maximum and I plug in every time I am home which can be multiple times a day. Departure charging would allow you to charge to 100% right before you leave.

Road tripping from a calendar aging perspective is not too bad on the battery because you don't charge to full normally and you hop between chargers (low depth of discharge).

The reason manufacturers don't tell you this is they don't want consumers to know that their batteries will die from simply non-use. Your battery can fail with 30K miles on it if you're only driving 2-3K miles a year

That full size map on the cluster is glorious.
Absolutely. I predict a lot of us will be using that one. This is certainly shaping up to be a very very nice update.

But where is CarPlay 🤪

Wassym is a semi regular on Reddit, He comments every once in a blue moon but used to do a Q/A. They got away from that. His username is u/WassymRivian

But, for some reason, he never answers my question as to when we’re going to get the V2H solution that has been promised since day one. It’s the Duke Nuke’m Forever of Rivian features.

There are a lot of false claims in this.
Haven't you watched the video about the cannonball run recently? Where they grabbed batteries from crash-tested Rivians that were sitting in a vehicle graveyard for months before being salvaged? They hooked them up and saw they were basically pristine (paraphrasing, but you get the point).

All the most recent data emerging is showing that
1- EV batteries are MUCH more durable than you think and suffer much less degradation over time even in extreme circumstances.
2- Fundamentally, even DCFC small-ish, non-optimized batteries in the desert (Arizona temps) have shown to have extraordinarily little impact on battery reliability and longevity
3- these batteries have different chemistry than most people think of (like your phone), and really is incomparable to anything that's non BEV.


Receipts:

https://www.firestonecompleteautocare.com/blog/maintenance/electric-vehicle-storage/


Don't be fear mongering.
Literally no one should be worrying about their batteries. The people charging to 100% all the time are in the same boat as people tracking their usage on a spreadsheet and trying to optimize for L2 charging at pre-configured timelines, within specified ranges at distinct temperatures... within a reasonable margin of error. The only delta between these two people is the stress and anxiety from needlessly worrying about nonsensical things.

The only *real* risk of the batteries not being used, as you're proposing, is if you allow them to completely discharge. THAT would be bad. But not using them much over the course of a year is absolutely not detrimental.

Go read some books.
