It matters in the sense that a parked car in the wind will cool to ambient temperature faster than it would when the air is still, but not in the sense that it will ever get colder than the actual still-air temperature. Wind chill affects rate of cooling, but (in the absence of evaporation) not the actual low temperature that is reached. 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, it's probably closer to true to say that "it does not matter".
- ghaff 4y agoWind chill is mostly a number for TV weathermen to use to hype up cold weather. It does matter to some extent for people in that they may want to be careful to cover exposed skin and wear something windproof. But it's more about dressing for cold windy conditions than about an absolute number.

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).
