Model 3 high pitch whine post charging

[NOCO24U]

Hi
My Model 3 (VIN 4XXX) makes a high pitched whine after it finishes charging. I was not able to notice this sound while driving. I made a video with the sound and a SpectraView graph. Does anyone else's do this? Is this normal?

(my car also makes the morse-code beeping that i started a thread about too: Model 3 annoying beeping sounds like 'morse code')

Our 3 (VIN 63XX) makes this sound during charging, afterwards and at random times. Overall, the car seems to make more and louder sounds than our S.
