one thing i just realized, with 92F outside, shouldn't i see some energy go towards battery conditioning? thank you
Another thing that might be happening is if the battery was charged at that temp, it was being cooled while plugged in and charging.
And then your 28% worth of driving might not warm it up enough to a display separate 'BC' number.
But, most likely, it may be that if you are running the AC for the cabin, the 'freon to battery coolant' heat exchanger is also always cold and the battery coolant could be flowing through it without generating a separate BC number. The coolant pump determines the flow rate needed to keep the battery happy.
Since the AC compressor is running it may be hard to quantify how much of the energy the BC loop consumed.
I'm not sure if I ever saw a BC number in the summer when I had the AC on.
I'm sure I get separate 'Climate Setting' and BC numbers in the winter when I haven't had the car plugged in for a while and it's colder than a w...
But in that case there is a separate coolant heater for the cabin and the BC loop.
edit: Another example of this is after doing a DCFC when the AC system was cooling the pack big time even though it was in the 70's when I drove off in the car with the windows open and just a little fan running I felt cooled air coming from the vents for quite a while after leaving the DCFC unit.
I don't remember if it displayed a BC number that time.
So, Old Mold, what you need to do is take one for the team and drive it in really hot conditions without the cabin AC
and see if you get a BC number by itself!!
I'd do it ,,, but I'm not that into it.....
Used '14 2LT w/ DCFC. +83k miles.
Mostly free charging! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 1st try car died again, 2nd try not covered / cost $800. 3rd try fixed the problem.
