M3P sound while supercharging in Rosemont

[011Charger]

Handful uh nights back I stopped in to the Fashion Outlets supercharger and recorded the vid below while in our 2022 M3P, could the sound be due to the colder temps out? The only thing I could tell from other times I've supercharged is before, the sound would be much more brief and seemed to periodically occur every two minutes or so while supercharging.

Sorry the mic on the phone didn't record that well, it helps to hear the grinding metal noise if you turn up the volume some.

Any/ all advice would be appreciated, thanks in advance

I charge at there quite often. Never heard of the metal sound. Most times SC gives me the poping sound in a cold day...

I’m glad to see that someone else has mentioned a popping sound while supercharging. I’m using a Supercharger for the first time, just as a test on the M3LRAWD I picked up Thursday, and I thought someone had banged on the rear passenger side quarter panel, then again a few minutes later. I heard a third one from right under my seat just before I was about to stop charging. Very weird.

So glad I came across this. Taking delivery tuesday and going on a road trip the next day and plan to use two stops at a supercharger. The popping would have freaked me out. Also will most likely be using the rosemont charger every now and then. @rollermonkey former Navy myself.

That's the famous Rosemont rumble........when you're a Jet you're a Jet all the way........

No, don't know, I've heard all kinds of odd, transient, and inconsistent humming sounds when charging at almost anywhere over the years, superchargers, home Tesla charger, mobile charger, blah, blah, blah. I probably wouldn't even have noticed that. Early on I might have noticed, but anyway, that's what the radio is for.........

That crackly plastic sound, on the other hand, pretty sure that was a water bottle in motion.......

the popping sound most happens on cold days. The battery is expanding due to the heat and it's normal.

Interesting, I've never heard a popping sound, and I often charge in the cold. What planet are you from? Earth or something? Different here on Mars........
