How do Electronically controlled CVTs, such as the one shown in this video , work? I'm familiar with centrifugally controlled CVTs but not very much with this type of CVT
Thanks.

Electronically controlled CVTs?

A suitable mechanism drives one of the cones in or out relative to the other one, on one shaft, and the one on the other shaft has a tensioning mechanism in it.
That "suitable mechanism" in this case appears to be a stepper or servo motor of some sort. In automotive applications, more commonly it's hydraulic. The electronics operate a directional valve that either pumps more fluid into the chamber behind one of the cones, or vents fluid out of that chamber.

Is there always slippage between the pulleys and belt during all phases of operation in a CVT?

The design intent is that there is not slip, but it's likely inevitable to be non-zero.
