Ideal charge percent to keep the truck at for daily driving?

[CyberGus]

10 months of storage?!

In an average year, your vehicle will spend about 11.5 months "stored" when you're not driving.

The good news is that you don't need to worry about degradation if you don't want to. For those that do, the charts are informative.

I don't drive my CT much.. I keep it at 60%. and go up to 80-100% as needed on those days I plan to drive a lot. Did this with my X for years, and it hasn't lost any range

Same here, don't drive all that much. 60% is ample for me with a decent buffer.

Tesla recommended MAX charge: 80%
Tesla recommended charge: 15% - 50%

Some stats from TeslaMate, just for data points.

The ride with 55,347 miles in our 2020 X, the 5,138 miles in the Cybertruck. The dip in the graph on the X around 18,000 miles is when it the front motor grenaded and the X was in the shop for a month. It was at a low SoC when it got there, around 40%, and down to 20% when I picked it up. Stats are a double edged sword (for me), I love having them but when I see things like the drop in range after sitting at the shop for a month it kinda sucks

The X we have taken on a number of long road trips, thus the 10.62 MWh of DC charging over the 55,347 miles. Some of segments of those trips required charge session above 95% to make it. At first I was stressing about the battery health, my wife helped me relax about that Would be interested to see some stats from other rides with over 50k miles.

If there is that much heat, then your wiring is sized incorrectly.

And from an electrical perspective, P=IR. So the same amount of heat (or wasted energy) is going to be loss at higher vs lower currents, since lower currents require longer charging times.

That could be true that the wiring is not sized correctly. My charging circuit is a six gauge wire with a 60 amp circuit breaker which should be sufficient enough for 48 A but that is at the high-level of what that circuit can handle.

When I charge at 48 A, the voltage goes down to 237. When I charge at 16 A the voltage is steady at 244. The power reading at the fuse box on the EV circuit during the 48 amp charge is 11,726 W and 3920 W at 16 A. So on my circuit, I get 99.6% efficiency 16 A and 97% efficiency at 48 A.

We could make the assumption that if I had 100 amp circuit with a larger wire that I may not see that voltage sag at 48 A.

I don’t know if it’s the wire or the converter in the Tesla. That’s causing the voltage sag.

Source of your second statement please.

Because unless there has been a MAJOR change, it is absolutely false, and they don't even allow the max charge to be set to those numbers.

Is whatever you are using to read the power that accurate? 0.01%?

And are you factoring in the amount of power that the truck takes just to stay awake to charge?

The voltage sag, that's the wiring.

It's in this thread bro and it's absolutely true.

And you're still confusing ideal charge with MAX charge.

I charge to fifty percent unless on a road trip. I think the optimum charge will vary for each driver. It just depends on your daily need.

Sorry, no it isn't

" Tesla recommended charge: 15% - 50% "

Show me! Prove me wrong!

A link to any Tesla source should be sufficient.

Uh, no it isn't.

That's for storage when not connected to a vehicle. That's not an "in use" situation. And a portion of that has to do with energy in the battery when shipping.

Lithium ion cells and batteries must be offered for transport at a state of charge not exceeding 30 percent of their rated capacity. Lithium ion cells and batteries at a state of charge greater than 30 percent of their rated capacity may only be transported under conditions approved by the Associate Administrator in accordance with the requirements in 49 CFR part 107, subpart H. Guidance and methodology for determining the rated capacity can be found in sub-section 38.3.2.3 of the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter).

And before you come back with a smart remark, in the very next section, "Transport" there's a statement about transport.

The regulations also require that individual involved in the preparation of dangerous goods for transport to be trained on how to properly package, label, mark and prepare shipping document

Did Tesla train you? No? So, I guess it doesn't pertain to an installed battery, just as the one above doesn't.


But the MOST amazing thing is that with most people charging to 80 or 90%, (although indeed, some are less) the batteries are still easily surpassing 200,000 miles in range.

Just how much are you expecting to gain?

 

[igs]

Uh, no it isn't.

?‍

50% is 30%?

 

[igs]

15% - 50% is consistent with this chart

 

[Woodrick]

15% - 50% is consistent with this chart

And the source of this is?

And what is the penalty for being at a "3"?
What is the range reduction?
What it the battery life reduction?

Do you not think that Tesla does anything to maximize battery life?
