Abstract Quasi-neutral limit and the boundary layer problem of the two/three dimensional incompressible Planck-Nernst-Poisson-Navier-Stokes equations for electro hydrodynamics with the general mobilities of two kinds of charges and in the bounded domain is studied. For the generally smooth doping profile and the physical case that the mobilities of two kinds of charges is different, quasi-neutral limit with a subtle boundary layer structure is rigorously proved by constructing one new λ-weighted entropy functional coupled with multi-scaling approximating expansion techniques.
