They have superchargers with fluid in them that work in much colder conditions. It seems that this is either this is Tesla choosing the wrong coolant mix for the climate (or, they got caught flat footed by the extreme weather that day), or they misconfigured the supercharger so it didn’t adequately heat the coolant so freezing conditions occurred. Either way, seems easily fixable for the future.
