Warming with blankets only works if the thing is itself emitting heat, to be partially reflected back via the blanket, or emitted more slowly through the blanket than without the blanket.
So how would a frozen car become warmer with a blanket, unless some subsystem within it is emitting energy?

Probably a reference to the well established practice of using block heaters[0] on diesel engines in cold climates... which AIUI are effectively just electric blankets. It's why you'll often see what appears to be a short extension cord dangling out the front of a big old truck where it snows a lot.
Obviously on an EV you already have much of the parts necessary to generate the heat, esp. if plugged in to charge... so it could just need the blanket/insulation part.
