going to leave it plugged in and in the garage and set to charge at departure time. so battery is warm when i leave.. never charge my model 3 full so was going to set departure time an hour after i actually leave so battery is warm just not at 100% when i leave.. thoughts?
I believe that the vehicle keeps the battery above a certain temp ( ? 2C = 36F ? ) if not plugged in, but if plugged in it will warm the battery to a higher temp. But what I don't remember now is if the vehicle warms the battery *during* the charge, or only after a full charge is *finished*, or *all the time* while plugged in. Does anybody remember?

At any rate, I also have used the technique of "set departure time to later than the real departure time so that it isn't fully charged" - but I live in Calif and don't have to worry too much about the battery temp.

Another piece of useful info is to use the "remote start" feature, which will "warm" the car for up to 20 minutes (you can also do it a second time). It will pull the first 3.3 kW of energy from the wall if it is plugged in (level 2 charging). ( "remote start" is described in the manual, you can turn it on with the keyfob and with On*Star, remotely, if you have an On*Star subscription). So I also suggest that you "remote start" the car in the morning, which will turn on the climate controls (to whatever setting you had them at when you turned the car off) AND it will start warming the battery pack. If you just want to heat the battery, leave the car's interior heater turned off. If you'd like some heat in the car, set the heater to (say) 72 degrees, and medium fan speed before you turn the car off. Again, you can do this a second time remotely. (If you are only going to drive for 5 minutes and park it for 9 hours, it's sort of a waste. If you are going to drive 30 minutes, it is *wonderful* to start with a warm car and a warm battery, heated by your house current.)

I have been doing the "remote start" using the keyfob. Onstar isn't worth the $$$ for me even though it would be cool to have the "free" internet that comes with it.. :)
appreciate all the tips. the temperature management is different than the "3" it seems. Going to play around with how best to charge..go to 100% each day or keep it lower.. be great to have a setting to set max charge though ..gives owner more control over charging. I am LOVING the car. great car to pair with the "3".
keep tips coming

still on lookout for rim..the chevy dealer quoted me $3400 for new oem rims!! no that isn't a typo

If it warmed the battery while NOT plugged in, that would mean when you return from your month in the Caribbean to a car left outside in the winter, you'd have a car with NO range left.

I do know after leaving my car at the airport for a weeks vaca plugged in, during the winter, I could see on my Chargepoint acct a series of heating sessions, about twice a day, if I remember it correctly.

I suspect that a cold car suddenly plugged in will use TMS to heat the battery immediately to keep it happy and healthy during the charge.
That would mean some of the 3.3kW would be going to the TMS and not to the on-board-charger.

Mostly free charging! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 2nd guess not covered by warranty and cost $800. 3rd guess fixed the problem.

I know that the Bolt (yes, different vehicle) will run battery conditioning when the car is not plugged in but only when battery is over 40% . (The "keep battery warm/cold" is also much less aggressive, not warming or cooling it as much when not plugged in.)

So, has anybody here measured battery warming behavior(s) on the Spark EV?

I haven't measured anything. I think that my Spark EV will warm the battery in cold weather when plugged in and the charge is complete. I have consumption monitoring as part of my SolarEdge system and observed two events this morning, one at 5:45 am and another at 8:00 am. It took about 1 kW for a few minutes. The garage temperature was in the low 40s. This is at 120 V. Charging had completed at 2:45 am.

I've been keeping track of the battery warming when the temperature falls low enough to do so but our weather is mild most of the time and this is the first winter it's been through. The 2C temperatures is what I see my car charging at unless I do a remote start or at the end of a charge cycle which is different than our Gen 2 Volt which warms the battery to a higher temperature throughout the entire charge. I will continue to add info to the data tracking thread I have created as I find out more.
