Got 2022.40.4.1 installed on my MY 2020 last week, just before I left on a trip from NY to Denver and was really hoping the battery preconditioning was fixed (according to the release notes). My real life experience with it, in chilly weather (20-30F), shows me it hasn't improved at all.
The worst case was in Wisconsin when the temps were around 20. The preconditioning notice came on about 60 miles away from the SC. I figured that because it was cold, this was correct. After about 30 miles it went off. I assume that means the battery was up to the proper temp. 10 miles later the notice came back on. I am guessing the temp of the battery cooled down enough that it would require some more heat. 10 miles later it went off. about 5 miles from the SC it came back on.
According to the new energy graphs, of the 50% battery used, 40% was for driving and 10% was for battery conditioning! That's crazy.
So my take away is that the battery preconditioning has not been improved. Using the preconditioning uses up so much energy that any time savings gained at the SC having the battery at temp is negated by the increased amount of energy needed to "fill the tank" back to where it would have been filled had I not used the juice up preconditioning.
The automatic preconditioning should be smart enough to only heat the battery once, based on outside temp, battery temp and time/distance to the SC. Not waste energy heating the battery so soon that it requires additional heating sessions to make sure you arrive at the SC with the battery all warm and cozy.
How about this - give us the ability to manually control the preconditioning, showing us the current temp of the battery and the desired temp of the battery. We shouldn't have to trick the car into doing it properly by navigating to a location that is close to the SC and at some point guess when it would be best to switch navigation to the SC.
Anybody else experiencing this, or is it some quirk on my car?
