...Good catch. That was a carry over from the previous post since it was preconditioned before taking the mileage reading. ....
The way I understand it, You can 'Precondition' the cabin before driving off, from the key fob or app. It will heat or cool the cabin
While plugged in it will use EVSE power. When not plugged in it will show up on the energy page as usage.
The HV battery pack is 'conditioned' which mean the TMS is heating or cooling the pack as required.
When plugged in, it is done in the background you can't tell how much power was used while the pack was charging.
Once the pack is at 100% SOC you can see TMS cycle on and off as required if you are on a networked L2 or your home EVSE logs it.
I saw my car's TMS cycling once or twice a day while plugged in at the airport for days in the winter, a while ago.
Side note: Yesterday my car was topped up at a public L2 around 11:30 AM and I was a good EV owner and moved it.
When I left work at 7:30PM, (long day...) after about 4-5 miles I saw on the energy page: 5% 'drive power (or whatever it's called)', 3% Heating and 2% Battery Conditioning. And I had the cabin heater working at 100% on the 'Climate Control' page.
I don't like seeing Battery Conditioning showing up while driving.
To me that means my pack was out of the happy Temp range for the first part of my commute....
So,,,, today when it's even colder, I'm plugged in at work using my L1 @ 12A. Slow, but it will keep the battery in the happy Temp range all day long!
Used '14 2LT w/ DCFC. +85k 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 / cost $800. 3rd try fixed the problem.
