Appears it was a bit damp at your location.
Do you recall the OAT and dew point?
Battery SoC and temp upon initiation of charging session?
kWh charging rate, etc..
Or did you spec the 007 package option with smoke screen, ejection seat, rotating plates etc.?
I drive at altitudes with cold temps and snow and have not seen this in two winters of driving.
I have seen something similar to what you experienced posted somewhere but cannot find it now. Will keep looking.
Yup, did see pretty much the same when charging on a wet day (about 0 deg C) after about 20min on an Ionity charger. Didn't even go over 150 kW charge rate.
