Does the 3.78% account for the efficiency changes due to software updates (which changes the constant)? Just curious.
Read my post over at TMC
The constant has not changed over close to 3 years of software updates

I did recently get "Scan my Tesla", but I can't seem to get a soc or Hx number out of that, but it could be I don't know where to look.
Hx no, but SoC yes.

Have you watched the Bjorn Nyland videos ? He presents a couple very good SMT tutorials

SMT is pretty clear that in the case of Tesla battery management there is
1. Nominal battery capacity when new
2. Current max capacity
3. Reserve (to avoid bricking)
4. A sliding scale buffer that starts at 0% when the SoC is "100%" and reaches 4.5% when the SoC is "0%"

The constant used to translate capacity into range DOES NOT CHANGE. That is just ignorance and FUD

Sage,

Tesla absolutely changes the constant with software updates where they have improved the efficiency of the cars. Thats been pretty well documented, and happened a few times over the past couple years. Telsfi appears to know how to account for it in its calculations.

Yes I watch Bjorn, he is my lunch entertainment with good info in there as well. I can see all the numbers your talking about, but I think some must have to calibrate it becasue when I look at current kWh it is all over the place, but the SOC seem very consistent. My favorite thing to look at is the mid cell temp and then if the "afterburner" or rear stator is running to heat things up (I have the single motor, smaller battery) . It helped me understand all the noises the car makes becasue I could see what it was really doing :)

Different models have different constants. Once you buy a car the constant does not change

Can you post a jpeg ?

It sounds like a kW gauge

Sage, I dont think that is correct. Does Tesla confirm that anywhere in its manuals?

I traded in the 2013 Leaf today. After 8 years and 80,416 miles, it never dropped a bar and left my hands with 86.14 SOH per LeafSpy. I had no expectation of it holding up anywhere near that well (and thus leased for the first half of its life), but long-life mode, the mild Seattle climate, and good luck made it the most amazingly dependable car I’ve ever had. Fare thee well, trusty blue Leaf.

I drove a 2013 SV that I leased for two years...for a total of five years, with lease extensions. I loved the car, but the range just wasn't quite enough. I too turned "Ana" in with 12 bars.
