Thanks so much about the info regarding balancing. That explains a lot and matches what I see. I keep an eye on balancing and regardless of what I do or how I charge, it always stays in balance amazingly well. Even after 206k miles and 5 years there is only a 3-4 mV difference (when it's charged 90% or more). At lower the state of charge the difference is usually a little more.
75kWh. On Ben Sullins vehicle. You can apologize to @vgrinshpun now.Since you're not willing to put anything at stake in defense of your position, how about this:
Post the following:
Photo of a "since last charge" on a 3 that comes anywhere close to the 78 kWh number. (This doesn't exist. photoshops or rooted cars don't count...) (edit: looked through my photos... best I've got is 66... so 12 kWh buffer?! Hahahaha)
I was just thinking of that video. And since it’s the LR RWD 3, Ben would have been able to use even more than 75kWh if Tesla has unlocked the extra 15 miles of range that they now have. Plus it was also quite cold then, as far as southwest climate goes. Ben was wearing a pretty thick coat. Is the energy used to warm up the battery at the beginning of the drive counted in the energy usage meter?
Yeah, the small deltas get very exaggerated/magnified at low SoC, and a bit at high SoC.

Yeah. I just can’t work up the outrage. The car delivers the range I was led to expect, and I never saw Tesla as purer than the driven snow to begin with.This is one thing that convinces me that Tesla was dishonest with the original kWh numbers...
I have done a lot of data logging and noticed in my 2014 Model S 85, the point at which it switches to constant voltage charging is always just under 90%.
One thing they're now able to do is to calculate out the capacity of individual bricks of cells (96 in the 85/90/100, 84 in the rest) based on a ton of factors and compute this in near real time, in a full range of conditions, with almost magical accuracy. They're basically running physics simulations (similar to how they calculate out unmeasurable metrics in the inverter firmware, like rotor temperature) of the entire pack based on measured power usage/charge, balancer usage, temperature, temperature delta based on coolant flow and coolant temp, predicting temperature gradients, and probably 100 more variables. This is the holy grail of proper balancing for safety and longevity for a battery pack. This is not a dumb system anymore by any means. Knowing the actual capacity of the individual bricks allows them to know exactly which ones need cell bleeders enabled, and for exactly how long. With this data, they can balance on the fly at any SoC, and just use top and bottom SoC windows for fine tuning, validation, and calibration.
Asked the friend at Tesla who leaked a bunch of stuff to me about this, and he said "Just post it"...
So, here's a screenshot of an internal document on the Model 3 battery.
Now seriously. Just stop trying to argue this.
