First - please do not suggest "just drive slower!" as an answer. Because not one of us bought these to do 50mph on the highway, and that is completely unrealistic in our modern society. It's likely to get someone run off the road. I have not changed my driving style from one vehicle to the next, and my highway cruising is long distances over frequently traveled routes, so I can SEE where the power usage has changed over time. It actually was lower when it was COLDER.
I'm asking for suggestions / places to look / things to try, and if there's anything I can check with ScanMyTesla or Tessie, I'd be happy to.
2016 X 90D. Battery currently showing 14.3% degradation, 224 rated miles at 100%, Tessie thinks the real world is 180. ACTUAL is more like 140. So there's either a mismatch in the BMS or there's something else going on. Cruising highway speed FLAT LAND (Florida, Georgia, SC, NC) is pushing 500 wh/mi. No that should NOT be that high. Previously driving the same route, power usage right after I bought this X at the same speed was around 375.
I've seen north of 500 wh/mi while towing (ok, that makes sense) but on the same trip in the plains, with a tailwind, was seeing 650. So this feels like something that is changing or turning itself on and off rather than something mechanical. Not towing right now, I'm seeing 470-500.
I've had the half shafts replaced, changed to a set of Tsportline wheels (and I can feel that they are definitely lighter than the stock setup) with slightly narrower tires (255) that are the same diameter outside as the 20" wheel setup. No extra electrical loads inside, no inverter (so that's all ruled out). AC is on, refrigerant load is exactly correct according to the sticker. ~25 and ~200 for refrigerant pressure with the system on. Ohmmu battery now.
Virtual support hasn't been terribly helpful, suggesting that I needed to replace the 12v battery and the coolant pump - but no mention of which pump, and there are no errors for anything there. The only errors I have seen are related to the falcon door calibration, an RCCM actuator, PresSnsDis (climate pressure sensor?) and now a new one that it is "unable to charge" on AC, when it still is charging just fine.
That unable to charge message (CHG_f018) started right after replacing the 12v battery, so maybe having everything powered off made it detect it. I swapped the 12v batteries around and that error is still there, and it's only been for the last few days. So I don't think that's related.
So.... Where to look next? Ideas please!!!!
