...you have no proof this isn't just a system fault.

Battery degradation to 50% capacity at launch isn't degradation. It's system failure.


Your destination miles would also have that fault.

So there's no reason to look. You'd notice your % peeling off at 2x the normal rate, as well.

I ride a short-range EV. I am super-familiar with what works in percents to miles on the main display. I just know it takes 15% to get downtown, and 25% back. It takes 25% to go up the hill on a hot day and 45% when it's freezing out. You just get used to it.

Because EPA miles don't represent your range, you have to translate anyhow. And you need to know the percentiles to know how dire charging is.

I'm not trying to argue or convince anyone of anything here. Just saying if you charge to full and it says half the miles it is rated for something has gone wrong :)

Long term, % is meaningless since capacity drops.
Short term, % is meaningless because of inconsistent topography.

Always look at miles.
That's incorrect.

Everything that has meaning has to be taken within the context of that meaning. For example, you could claim the outside temperature is meaningless because the wind chill and humidity impacts how we percieve the temperature. I would say the temperature is meaningful, you just need to be aware of the other variables.

The same is true of the EPA range remaining. One needs to understand the miles remaining are not absolute, they are relative to standardized test conditions. In that context, it's VERY meaningful.

What I find far less meaningful is the remaining miles on my F-150 (because they vary depending upon whether I have been driving up or down a hill in the last 30 or so miles). I never know exactly what that number means. On all my Tesla, I know exactly what that number means.

Oh, wait, I see you were saying the % number is meaningless. Again, that's incorrect. I use that number (in conjunction with the miles remaining) to inform me how my battery's condition is doing. I also use it in the same manner I use a fuel gauge on a legacy ICE vehicle, as a general indicator of how much "fuel" I have left.

I stand by what I said earlier. I'm not going to reiterate for Johnny come lately.

Can I get the last 10 min of my life spent catching up on this thread hoping for something meaningful or some resolution back?
Yes, if you copy Customer Service with a fully documented request in triplicate, marked urgent and accompanied by a $100 payment.

Wasn't it already resolved automatically by the trucks BMS system recalibrating on its own?
Oh! Did it? I didn't see that post

Edit: this is unresolved. Last post from op was Friday saying an appointment was scheduled.

I'm not trying to change anyone's mind, use whichever view suits you best. Percentage gives 1 data point, range gives 2 data points. I happen to be a data person, so I prefer the extra information. I wish Tesla gave me as much much readily available information as my Zero. Cell balance and pack voltage can give useful information when the SoC is at the lower end. That said, the navigation makes it a non-issue for most people. You definitely don't need the details to get from point A to point B.

Today was the day. I had THE service call. I was told they would diagnose further, but they found that a fuse blew, but the system did not notify me. Whatever the blowing the fuse means. I get the CT back on Monday (so I am told). I will update further here.

There are very few fuses in a Tesla, but the notable ones are in the battery pack and losing one would literally halve the pack.

I wonder if that's the one that failed? If so, that's a pretty chunky piece of metal. It was probably something else.

I have a 2013 Model S that I purchased new 11 years ago. Computers upgraded and battery upgraded to 90k maximum that can be installed installed into a 2013 frame. I use distance most of the time instead of %. I have noticed that after a software update some time ago that my car also will show a much lower distance than what the supercharger has added. In fact it will lock at a low distance even while the battery is still being actively charged. However, as soon as I disconnect and start driving it will increase to show the correct charge. I always attributed this to a software bug that was introduced by a past update. It never bothered me after I saw that it would correct after I start driving.

I plan to update this thread once I get the CT back and the dealer addresses it.

I thought it was something like too but now I know it was something physical like a fuse.
