Are you changing your charging limit after latest update?

[CrazyOne]

Right now, I charge 1 - 2 times a week and use it between 20% to 70%. I will probably set it to 55 and use it on the 45 to 55 range for normal use.

I’m setting mine to 50% for now. I plug my truck in every day and I work from home. So it might work for me. Normally I still charge to 100% on weekends because we tend to head to the mountains on some decently long trips.

I have not gotten the update yet, but from the photos I’ve seen, I like the way Rivian implemented this. It looks like you can still select 70/85/100 easily, but then there’s also the slide for custom limits. It’s nice to have both. Tesla has just the slider and the OCD in me gets annoyed when I can’t just set it to a specific percentage. The slider always seems to stop a little higher or a little lower than what I’m aiming for.

Like many others, I’ll stick to 70% daily because it’s fits my needs and is what Rivian recommends for long term battery health. I’ll set to 95% for most longer trips we take and maybe go to 100% just a little bit before departure.

for long term storage - set at 50% and plug in...

Lithium Ion batteries, such as the Samsung 50G model cell that our trucks use, do not suffer from memory like Ni-Cd batteries did.

So I don't need to worry about running it down occasionally? That's good to know.

You should run it down occasionally because the BMS will be better able to estimate how much energy is actually available when the battery is run down that low afterwards. You don't have to go to 0 or 10%, but I would aim to at least run down to 20% once a year if you ever intend on needing capacity below that.

Okay so at a once a year frequency sounds easily doable.

"Nominal" cell voltage

You should run it down occasionally because the BMS will be better able to estimate how much energy is actually available when the battery is run down that low afterwards. You don't have to go to 0 or 10%, but I would aim to at least run down to 20% once a year if you ever intend on needing capacity below that.

Occasionally running it down as low as you're comfortable going will expose any bad or below average cells as well. I'd try to run it down to under 5% at least 2X per year. I've built quite a few batteries from individual Li-Ion and Lifepo4 cells (for our boat, Jetski, lawnmower, portable 12V packs, etc....) and they're all good at nominal and top cutoff voltage, but the true story of a cell is revealed near the low voltage cutoff point.

I'm planning to use 90%. I don't have easy access to a charger and Tesla has used 90% for years with minimal degradation.

i'm wondering where Rivian get the 85% from? Aren't they use the same battery type?

Probably because when they launched the software it had only three options 70, 85, and 100. 85 is exactly 15% more than 70% and 15% less than 100% -- right in the middle. It's simple and evenly spaced. If you're only going to offer three options then it makes sense.

well ackshually, 85 is 21.43% more than 70

I'm unchanged, I charge to 100% and go down to 20% after about 4 days then recharge back to 100%. That's for during the week commuting to work. On the weekends I do whatever I need unless I'm road tripping. I don't charge daily.

The service center plugged my truck in Saturday afternoon and it hit 100% a few hours later. Stayed plugged in till Monday morning. No deg what so ever.

My truck got the update but not my android app. Anyone else in this situation?

Separately, my preferred use case for this a sort of manual scheduled departure. Like I did with my Model 3, I'll keep it at 50-60% most of the time and then increase it to whatever I need such that it finishes charging just before I'm ready to leave. That way the battery is nice and warm at departure.

 

[SourGrapes]

I like to live dangerously, so I charge to 11%. Plus, the truck is lighter and more sporty with less electron baggage to weigh it down!
