Charging noise...

[NAL]

Every once in awhile there is a loud fan type noise when charging my i3 Rex. I have to assume it's the fan cooling down the charger or the batteries. It goes on and off intermittently and ceases when I stop the charge. Anybody else experience this? I'm using a 40A, AeroVironment charger.

Depending on the ambient temperature, this is normal. You'll also notice some sounds if you choose to precondition the car prior to leaving.
