I just got my charging unit upgraded to 240v via EVSE.com. Prior to this, I'd been trickling charging at 120 v all the time. I just noticed that my 2014 SV is making a whirring/humming while charging at 240v with the EVSE.Com upgraded unit.
I never heard any humming/whirring at all while charging at 120 v for the first year.
1) Is this humming/whirring normal for 240 volt/level II charging?
2) Why didn't I hear it at all charging it at 120v/Level I?
I could post my own video, but this YouTube Video records exactly the same noises that my 2014 SV is making while charging via the upgraded EVSE.Com 240v unit.
