If (Tesla) you come off the ski hill and just drive to the SC then no, the battery won't be warmed enough. But if you ask the car to navigate to the SC then the aux heater will kick in and it probably will be. Now this depends, of course, on how cold soaked the battery is, its thermal mass, how big the heater is etc. I'm guessing that in the majority of cases that 20 minutes of aux should do the trick as that seems a reasonable design target for Tesla but even so it is possible that one could experience circumstances outside the design envelope. But this is nitpicking. What I want people to be aware of is that if you pull up to a 350 kW EA station in your brand new Rivian and don't get 350 kW charging that does not necessarily mean that either the station or the car is broken. There of plenty of factors other than failure that can limit charging speed.Understood. But not everyone has time to pre-warm the battery prior to supercharging. An EV sitting in freezing temperatures for 10+ hrs while skiing and then driving 20 minutes to a Supercharger will not be warm. It happens.
