Hyundai prefers you charge on AC instead of DC to increase battery life, but in cold weather you need to warm up your battery before charging on DC. This is possible until -35 deg Celsius, then the battery heating systems stops.

Do they mean that the battery itself is at a temperature below -35c, or the ambient air temperature? I cannot believe that the battery management system would ever allow it to become that cold.
Hyundai said in the manual “if the battery temperature drops below -35 deg C, the high voltage warmer system may not operate”
 
I could understand why the battery can't warm itself at low temperatures, because that would mean it is discharging while cold. What stops a plugged in heater from working in the cold?
Electronic components are classified under normal grade (0 -> 70 deg C) or military grade (-35 -> 150 deg C) for automotive. (AEC200) There are components that have an even larger temperature range, e.g. from -50 -> 200 deg C. C, but it is the weakest electronic component that determines the temperature the whole can withstand.
 
I had no idea that the batteries were rated for such temperature extremes. If the car is plugged in, is there any temperature management of the battery when the car isn’t charging? Will the car precondition the battery if you have scheduled a departure time?
When the car is plugged in, you can charge the car on AC until 100% which heats up the battery and electronics, but once at 100%, you need to keep the car warm inside at extremely low temperatures under “sheduled Charging and Climate”, which also heats up the battery. You could regularly retard your start time via Bluelink and also leave the battery heater on until the worst of the cold is over.

With these extremely low temperatures you also have to take the liquids into account. The 2 cooling circuits and the windscreen washer product must have sufficient antifreeze. The transmission oil normally becomes too thick to lubricate the transmission. These rules also apply to ICE cars. That is why they have to heat up the oil pan in Siberia before they can start the engine.
Coming back to the I5, if you have of course plugged in the charging cable, that also means that you have electricity there and if the car is in a garage, you can also heat up the garage with an electric heating device. If this device does not consume too much, you can still connect it to V2L, in such a way that it consumes electricity from the battery and that with the connected charging cable, the battery continues to charge keeping battery and electronics warm. :p
 
I'm looking for infotainment manual for Ionic 5.

I wonder does Ionic 5 support garage door to open from the car (carlink)?
I didn’t found that in the manual. So I think you need to use Phone projection to have Apple Carplay or Android auto and make use of Home app or Google home app to open your garage door.
