Power Quality - significant dip during EV charging, causes?

The squirrel thing is hilarious. I also like the idea of sharing sense with the neighbors, but might I offer common.sense.com as the address??

I have an update to share also. The utility came out today. I showed them the data log in the app, they were super impressed. I think this guy might be buying a sense for his home. What we found was the transformer has signs of leaking fluid. I tried to get a picture where you can kind of see it:

Needless to say, I am really excited. I should have a new transformer in the next couple of hours. Hoping that is going to be the fix. I will report back either way once that is in place and let everyone know how it turned out.

Thank you all for the help and analysis to figure this out, it made the conversation with the utility super easy and right to the point.
