Mist from front grill while charging

[FrankNCCT]

I was just on a supercharger in Rhode Island and saw a fine mist coming out the front
Anyone seen anything like this
Called Tesla they said no risk but it makes me nervous the battery is heating above normal

Was it cold outside?

 

[FrankNCCT]

40ish other cars charging had no mist

Maybe they had driven less and packs were cold?

Any pics? I would have been interesting to trace the source, though I get it was probably pretty darn cold.

Model S pulls cool air in from the front and pushes warm air out from the inner front wheel wells. It shouldn't be pushing anything out the front grill - if this keeps happening keep an eye on coolant levels. The radiators are in front and if they are leaking you could be seeing coolant "mist" coming out.

Behind the front grille is a small radiator. On cool days, when the car only needs to cool the battery some, it will use this radiator to cool the battery instead of starting the compressor. This is likely what you were seeing.

It is a chilly rainy day, so the humidity is high. If the car is ejecting air warmer than the outside (because it is cooling the battery as it is warmed by charging), the cool outside air cannot hold as much humidity as the warm air from the AC unit, so the moisture condenses. Also, if there is moisture from the rain on any of the metal surfaces of the AC unit, it may be getting evaporated by the warm equipment, and then condensing in the cooler air.
