Volt going to deep sleep?

I'm going to have to try to experiment with this a little, but I had this weird occurrence today when my Volt was charged at home but sitting with the cord plugged in. The car finished charging the previous evening and I had turned off the smart plug, but I didn't get a chance to unplug it. One full day later, I unplug the cord and I forget to unlock the doors. The cord theft alarm didn't go off immediately. 5 hours later, my car alarm goes off and I get the Onstar notification about my cord.

I kind of vaguely remember reading in other threads about how the Volt can go into some sleep mode. It just seems weird that an event like the charge cord alarm doesn't wake it immediately. In all of my previous charge cord alarm cases, the car was actively charging and the alarm went off right away.

If I had not turned off my smart plug, I'm guessing the car would not have gone into the sleep mode and I would have had the alarm go off immediately.

The "Smart" outlet uses as much power as the EVSE does when idle, utterly pointless to have a smart outlet
There is a 2W draw when the car is done charging. I set the smartplug to turn off after charging to prevent the extra draw.
Sorry to bust your bubble, but the tar load of the smart outlet ( it has a power supply, computer an circuits always powered ) is typically the same 1-2 watts, meaning you save nothing.

And as others have said, the battery conditioning and 12V battery maintainer are necessary loads. If you don't supply grid power for the conditioner, the car will just draw if from the HV battery, which you will have to recharge later ( no savings not plugging in )

Bottom line, trying to outsmart the design team of the Volt isn't happening
