Interior preconditioning

[N1naz]

FYI when pre-conditioning at home (or anywhere) and plugged in be sure you are providing at least 32 amps to the MachE. I noticed today that when pre-conditioning is first started it will draw about 32 amps then slowly drop to about 25 amps, this is with a (set) 90% HVB SoC. I'm assuming that if you provide less than this it will either draw from the HV or LV battery or provide less preconditioning (IE heating or cooling).

I agree and this is my story:
At at Va Ski resort with only 110 at the house we stayed at. Plugged it in and while it was outside the first night (12 F) it added about 1 mile per hour. Second night I have it in the garage (about 45F) it added about 3miles per hour.
The morning we were going to leave I wanted to precondition the interior to save range. I had the SOC to 85% that night. At 8am I had it precondition to Warm the cabin and save range. After preconditioning and still plugged into 110 the SOC dropped to 82%. It took more than the 110 could provide to precondition the cabin.

The good news is I was at the top of the mountain and when I drove down the mountain 20 miles later I was at 86%.

Recap: It took more energy to preheat the cabin than the 110 could provide so it used the 110 and battery to precondition.
