Yeah, Sadly the quality of packs before about VIN 60k on Model S was
spotty. That shouldn't happen, but seems to on those older packs. Doing
the periodic balance may help avert that.
Did you get any alerts, such as BMS_u029_dSoc_Limiting or
BMS_u018_SOC_Imbalance_Limiting?

Thanks Phil for the informative reply. I plugged in immediately when getting
in the driveway and waited a couple hours before unloading, chain sawing and
splitting the wood (with an electric Worx chain saw and Swisher electric log
splitter).
Last time I charged to 100% was at Cocoa Beach Flor
My 74kWh 2018 Model 3 has this:
BMS_energyBuffer: 3.10 kWh
So at 0% user-indicated SoC, there is still 3.1kWh remaining.

For a Tesla? No idea, but my gut feeling is that when the
instrumentation indicates 0% state of charge, there's probably still
5-10% left in the battery. You'll be fine. Read your warranty just in case.

You are fine, just don't let it sit at low SoC. The "battery damage"
comes from the fact that Tesla's BMS on the 3/Y are somewhat parasitic, and
continue to suck power from a discharged pack. There is added degradation
from time spent at low SoC, but not "damage".
You do not need to do a balan
Hi folks
I just did a bad thing , hauled a bunch of firewood in my 5x8 Lowe’s trailer
behind my Tesla Y and the range dropped more than I thought it would. I didn’t
run the mini split heat pump and kept speed at 45mph (much to the chagrin of
red neck truck drivers behind me) and got home at 0%.
