well technically since the Model S was introduced. IIRC the OG Roadster doesn't have a buffer and you can in fact "brick" the pack if ran to 0.Forever

True, I was just imagining how the current owner group would handle that. Not well I think!well technically since the Model S was introduced. IIRC the OG Roadster doesn't have a buffer and you can in fact "brick" the pack if ran to 0.
Similar degradation but in only 3000 miles. Not good.Just for giggles did not charge this week, ran the car down to 2% let it sit a few hours (I hear this helps the car to take readings) then up overnight to 100% and slight improvement. Now 7 vehicles have lower range so I am in 8th place. So out of the 58 vehicles so seems about 14% of the similar mileage cars low end range like me.
What I would like to see TeslaFi do is add in charging habits so that you could see if similar charging habits leads to the rated range. This could also provide info into what charging habits yield the most rated range. After all the charge history is there for every car could be interesting to see if there is any correlation.

Over what time period? Not just miles but elapsed time have impact.

Over three months.Over what time period? Not just miles but elapsed time have impact.
Damn,
Full charged for me now is estimated at 271 miles (100%)
It has been on a downward trend and i dont know if it will stop.
I think it is best to really not charged until you are low to help gauge how much kW your car really has.
I have done this recently and ran it down to roughly 2-3 percent. The car recorded a usage of 62 kW. I dont think I have ever see a consumption of 65 or greater during the time driving the car.
Maybe they sold me a 62 kW mid range car? idk.
And how DO you charge? Can you list the last 2 months of charging, roughly if not perfectly? Is that just an extrapolation of your 100% or have you actually charged to 100%?Haven’t really changed how I am charging...

I have charged to 100% twice since owning this vehicle. Both times were for a trip.And how DO you charge? Can you list the last 2 months of charging, roughly if not perfectly? Is that just an extrapolation of your 100% or have you actually charged to 100%?
How the future 4680 batteries will be replaced?Its a P3D
They are replacing the entire battery pack
This is really great, but I wish you gave a little more detail as to how long you maintained each different charging habit...what resulted in what effects, and what was the protocol for when you regained that bit at the end. Thanks.OK did some messing around just to see what happens below are the results.

Decided to ignore the "a plugged in Tesla is a happy Tesla" and let the car run down by just not charging everyday and just using the car until it was low.
1. Down to 2% up to 100% timmed for next days trip.
2. Down to 50% up to 90%.
3. Down to 15% up to 90%.
4. Down to 5% up to 90%.

As you can see estimated range at 100% was hovering at about 282 then I did the 2% to 100% charge but not much improvement as there was a 90% charge just before at the same range. But after a few more down below and only back to 90% there was some improvement that seems to be sticking around.
Another thing I noticed is when the car is at a low charge under 10% you can see it is doing something. I noticed that the % starts to fluctuate while you are driving. Example you are at 7% it goes to 6% and then few miles back to 7% but I have been driving at a steady speed. So I think it is finding its bottom and calculating what the bottom really is just like it does when you charge to 100%.
At any rate my rated range is still low but I think this proves somewhat that charging habits can affect your rated range.

I drive 100 miles (round trip) two times a week (yay COVID). Otherwise I generally leave the car plugged in.

I hope you understand that you are not “regaining” range. You are simply dialing in the estimation. The amount of actual energy the battery holds and therefore the range is not changed by your charging regimen.The details are there maybe not clear.

Meaning normally no matter what the charge was down to could be 85% even 89% I would just plug the car back in and charge it back to 90%. going with the "a plugged in Tesla is a happy Tesla". Some more info before pandemic sometimes we would get down to 40 or 50% a few times a week but now and during pandemic most of the time it is only down to 70-80% once in a while lower. Looking at historical data there is no difference in rated range with either charging habit. The only way I improved it was by going low below 20% and charging back up to 90% or more.
So what I have been doing is just use the car each day and only charge when it is down to 20% or less. Now last charge from last night I am still maintaining 287 rated max range. So it seems that shallow charging does have an impact on the 100% full charge rated range.
IMO a key observation:

So I think it is finding its bottom and calculating what the bottom really is just like it does when you charge to 100%.
I have good feeling if I were to keep exercising the battery low to high I will regain rated range. I think this would be most effective by going from 5% or less to 100% several times so the BMS gets a good feel where the bottom and top are.
I hope you understand that you are not “regaining” range. You are simply dialing in the estimation. The amount of actual energy the battery holds and therefore the range is not changed by your charging regimen.
