My guess is that it would work fine at 120 volt charging (but your
charging speed may be slow, as alot of the power would be going to
condition the battery.)
Generally, the only thing in the car that sees the 120v is the battery
charger (taking the 120 volts up to the 3-4 hundred volts the battery uses.
Everything else in the car runs off of either the HV battery system, or
the 12v accessory system (which is powered by a DC2DC converter from the
HV battery system.
So as far as the car is concerned, the voltage of the input charging
system does not matter.
The only issue I see is that at 120 volts, you can only get 1-1.5 kW
into the vehicle, and if the battery heater takes 1.8 kW, continuously
it may not be able to keep the battery heated without discharging the
battery.
For this reason there may be a software lock that prevents cabin heating
or battery heating when plugged into 120 volts....but I kind of doubt it.

Thanks!
My biggest concern is whether battery management works on 120v charging.
My son who is looking at an EV in Alaska will be in rentals with only
access to 120v and without owning the outlet might not be able to
switch to 240v.
So, does BMS work on 120v? What about "remote start" (compartment conditioning?

If you leave it plugged in, I suspect it would do ok, maybe 20% range reduction?
From what I've read, if the car is plugged in and the battery temperature
drops below 37, or climbs above 95, the battery thermal management system will
turn on.
So, as long as it isn't so cold that the 1.8kw heater can't keep up, the
battery temp should stay around 37 degrees.
I know that here in AZ, if I leave my Chevys plugged in, I will occasionally
here the cooling systems run to keep the batteries cool. I haven't noticed
them doing this when not plugged in. Then again, where I live it only
occasionaly get's above 95.

Is buying a BOLT in Alaska a good idea? In Anchorage for example.
Anchorage is the biggest city in Alaska, there is little else to do within
the 250 mile radius of the Bolt, and adventures can come in the summer
spring and fall.. Just stay home iin the winter!
At least an electric is not somenint that has to "start" in -40F, it just
runs
THoughts?
