Don’t electric vehicles actually just move pollution to another location? 

No. Plug-in electric vehicles use power from the grid which comes from power generation plants. Power generation plants, even coal burning ones, are inherently more efficient and less polluting than vehicles due to efficiency of scale at which they convert fossil fuels to electricity.

Also, an electric car is far more efficient than a gasoline car, so the amount of pollution generated by producing the electricity to drive an EV a given distance is much less than the pollution from the gasoline to drive an internal combustion car the same distance. Whereas an internal combustion engine car – even those powered by hydrogen, ethanol, and biodiesel – can make use of only about 20 percent of the energy that it consumes, a battery electric car is able to put more than 80 percent of the energy it consumes to use in moving the car down the road.
