iPhone typing. This particular 12 pro max has a penchant for doing very very odd things. Corrected.
Are you saying that you charge to 90% overnight and then when you unplug in the morning the car says itâs at 75% state of charge? Thatâs an entirely different problem than what you initially described and isnât normal behavior.
Are you using the preconditioning settings? Instead of remote starting (which Iâm guessing youâre doing shortly before you leave), preconditioning settings on the timer will take care of this about 15-20 minutes beforehand, which also gives some time for the charge to catch-up with whatâs being used to precondition (especially if youâre on L2 and not L1). Both run off the battery to do it, but the length of time that preconditioning runs is probably longer than what youâre doing with a remote start, and my guess is that the battery isnât catching back up to a full 90% from when you leave. Still, shouldnât be leaving with 75% charge. Iâd check to see if your charge window accidentally set itself to something short or unreasonable and open it up. I had that happen once to me when ârecommended charge timesâ suddenly came down in FordPass from my utility provider, even though we donât have time of service billing.
In addition to rounding, Iâve found this is also an artifact of when preconditioning stops vs. how long the charge is running. For example, if I pull the plug in the middle of preconditioning, the charge hasnât completely kept up with the preconditioning process, and 90% rolls to 89% really quickly. If preconditioning is complete and Iâm a few minutes late getting out, the charge has replenished back to the âfullâ 90%, and it takes a while before I see the drop to 89%. This is similar to leaving it plugged in for a 90% charge and then taking it out in the middle of the day without the preconditioning process. If itâs not particularly cold, that 90 to 89% roll-down happens slower than if I caught it in the middle of a preconditioning cycle.
I get that. But then I don't understand this comparison with an ICE car leaving the gas station with a full tank of gas.
A lack of understanding. His battery is still at 90%. His RANGE is predicted to be less due to the cold. Identical to an ICE vehicle with a tank at 90 or 100% full, but it's now cold and it has winter gas. A 20% drop in performance for an ICE vehicle in winter is totally normal also. Same level in the tank, less MPG.
Exactly, basically the reduction in range is merely the MME predicting that based on the cold, I can only get 155 miles instead of the 190 I got before.
Right.
You might still exceed the GOM estimated range, but your winter range will definitely be lower than late spring and summer range.
