How often do we need to plug in?

...Perhaps I haven't read the various comments, threads, and information carefully enough (or maybe I've been retired so long my brain needs pre-heating to function properly?) , but I remain confused about whether the EVSE plugged in to the vehicle will enable any warming of the battery when the battery is not charging because it's reached whatever SOC limit was set, and even if the user has not set any schedules for departure and so on. In other words, if you do nothing except leave the charger plugged in after charging has shut off, is any battery warming effect possible? It seems to me the answer is probably "no", but electricity and these complex systems are all pretty much in the realm of magic to me, so maybe it is possible through the magic of magic.

As I understand it, staying plugged in after charging is complete will keep the battery warmed to at least above freezing (32 deg F).

Setting a departure time will heat the battery up to 60 deg F.

At least I think this is the conclusion from @Mach-Lee.

Also, to be able to have enough power to run the heater that warms the battery, you need a 240 volt and ideally a 32 amp EVSE.
