Representation of nuclear charge/potential for Poisson equation (DFT)

Hi, While reading through the literature, I have noticed that Poisson equation for nuclear potentials is solved with point-charge assumption, even though dft formulation is expressed using pseudopotentials. What can be the reasons behind that approach? What can be said about the energy difference be...
