Anyone with experience parking their Model 3 outside in cold/snow conditions? Unlike the Model S/X, the Model 3 does not have a dedicated heater for the battery, and I am curious to know how preconditioning/heating the battery in the Model 3 works. I understand that the Model 3 uses software to direct heat from the drive train even when parked to warm the batteries. Having only a one-car garage, we will have to rotate the two 3's between a 220plug in-garage, and a 110plug on the exterior. How will our Model 3's hold up in extreme cold weather conditions?
