> Since the concern with loss of range or or starting capacity usually has to do with how the batteries perform at at extremely low temperatures Isn't heating the cabin also a major component of the concern? That's where heating the cabin on grid power would help get some range back (assuming the battery is fully charged; if it's mid-charge then you're just shifting the grid power from charging to heating so the range will continue to suffer).
