Going out of town - best way to tender?

[Woodrick]

Nope not if the contactor isn't contacted. Drain is also irrelevant if you're plugged in which OP will be. Finally, SOC has nothing to do with drain if there were any.

And under what condition will the contactor never close? None. Phantom drain is going to drop the 48V battery and the traction battery has to come online to charge it periodically.

Blows my mind that this is so hard for you to understand, when there seems to be literally thousands of messages talking about phantom drain discharging the traction battery.

Drain is irrelevant if you're plugged in. Do you even read before spouting endless nonsense?

It’s best just to let me drive it for the month. Besides, I’m a hg pilot, too.

it would work great - just installed racks yesterday for my Wills Wing U2

I went on a 11 day trip and the battery drain was from 77% to 73% (SW version 20.9). It was parked outside on the driveway.

-Disabled Cabin Overheat

Taken completely out of context.

That's the SoC that a disconnected battery should be stored and shipped at.

If the entire truck is being stored or shipped, the same rules apply.

The electronics are programmed to use less power at that level. And if there's an incident, there's less power to be released.

Why would drain between 50 and 45 percent be any different than drain between 80 and 75 percent?

Chemistry.

I don't think it matters if you are charged to 30%, 50% or 80% if you are still plugged in because your charger is going to top up the battery from any effects of battery drain. Why would drain between 50 and 45 percent be any different than drain between 80 and 75 percent? I'm not convinced that it would be.

It matters a lot.

 

[TeslaKen]

It matters a lot.

No you just made my point with that chart that there is more stress caused by temp differences than between Soc when comparing 50 to 80, and look at the left side of the chart, 1 tt 10 in stress, what does that even mean? My battery will feel sad due to stress? Is that physical stress is the battery expanding in size? Is it collecting more dendrites? Again what does stress level even mean? Looks like 75 to 80 % soc is not significantly different from 45 to 50 soc in any meaningful way....

2.5x is not significant?

 

[TeslaKen]

2.5x is not significant?

Huh? At 20c it is .5 to 1 neither of which are meaningful without knowing what the scale even represents...

Yea, that's literally an100% to 150% increase. You don't think 100% to 150% increase is significant?

No, not when I don't know what the scale means. What does 1 mean in terms of impact to the battery? What does 2 mean? What does 5 mean?

Maybe 1 means that you have a 1 in a million chance of losing a single battery cell within a 24 hour period. Maybe 2 means you have a 2 in a million chance of losing a single battery cell within a 24 hour period.

Is the additional 1 in a million chance something that will make you charge at 50% instead of 80%?
50 is .5, 80 is 1.5
Both values are incredibly low on that scale. (0-10)
Is the difference of any significance vs. having 80% of my battery on tap ready to go vs. only having 50%?

What is the charge time from 50% to 80%? - This is a REAL cost, it will cost me time to charge from 50 to 80 when I want to take my truck somewhere.
What is the value of MY time to make that charge? - again a REAL cost
Is the value of MY time greater or less than the "potential" value of an impact to the battery between .5 and 1.5 on this scale? - Impact to battery is POTENTIAL, it may or may not happen, and if it does happen, we have no idea what that impact is from this chart.

In other words you are taking this chart to represent a hell of a lot more than what it really does.

I don't blindly follow charts, especially those with no citations, no source, no backing data presented. If you can present hard data that the cost of moving from .5 to 1.5 outweighs the cost of my time then I'm happy to listen to those facts.

For you it's a win-win because it saves both time and degradation.

 

[TeslaKen]

For you it's a win-win because it saves both time and degradation.

So as that video says, Depth of Discharge can cause issues for battery life, you are better charging several smaller charges, like going from say 65% to 80% in use than going from 50 to 80 or 25 to 80 etc. The video also says that as long as temperatures are not hot that you can store a battery with a higher state of charge but if it is hot then store it low (video suggests 30%) yet chart above shows no difference between 30 and 50%.

I'm not suggesting someone store their battery at 100%, what I am suggesting is that if it isn't hot then storing at 80% vs 50% will likely have very little if any difference in the degradation of their battery but will have an impact to driving range and convenience.

I honestly don't care at what % other people store their batteries, I've had a Tesla for almost 10 years and routinely charged to and stored at 90% with very little degradation across multiple models. I am charging at 80% on the Cybertruck because I'm being more cautious given the early nature of the truck and its batteries, and the Cybertruck seems to be much more accurate in predicting range and burn rates than any of my prior Teslas.

I'd still like to know the data source behind the chart you showed and what the numbers actually represent.
