Benefit of leaving the truck plugged in when the weather is cold?

Now that the weather has turned cold, every time I shut down the truck, I get a message on the screen that because of the outside temperature I should leave the truck plugged in.

My question is if I am not charging and have not set a destination time, what is the benefit, if any, to leaving the truck plugged in during cold weather?

I only plug in if travelling the next day any real distance but last 3 days I never plugged in and saw very very little reduction in battery percentage with 20km daily run arounds(-7 to-15C nights) and only pre started the truck for 15 min prior to leaving, all worked as always does. I do plug in for bigger trips where I will use 60-100 percent my range and pre program my departure for preconditioning which takes 1 hour.
Keep in mind that leaving your vehicle plugged in when it is very hot or very cold allows the truck to prevent stress on the battery. Whereas the unplugged vehicle will still keep the battery temperatures out of the danger area, when you get in to go it still may be pretty cold. We can begin the argument of how much stress it puts to use the battery cold, however most experts agree that it does stress a lithium battery to use it cold.

Conversely, most modern EVS will use a little bit more power to keep the battery in the "happy" zone when it is plugged in. The "happy" zone is the threshold where the stress is zero or negligible when the vehicle is used at that temperature.

For the longest and happiest battery life, most manufacturers will tell you to keep the vehicle plugged in, especially in extreme temperatures.
More learning of EV's from here, will keep her plugged in:whistle:
