eBike technology explained

Hey Lectric Owners!

I've been loving my XP 3.0 for my daily commute (about 10 miles round trip, mostly flat with a few small hills), and it's got me thinking a lot about the tech under the hood. Specifically, I'm curious about how the different pedal assist levels (PAS) actually work with the motor and battery. Does anyone have a good, simple explanation of how the controller manages power output based on our pedaling? I'd love to understand it better!
