The invention discloses an immune genetic method for planning and improving electric automobiles facing an urban distribution network. The method comprises the following steps of setting decision variables; producing initial populations; carrying out genetic operations; carrying out immune genetic operations; developing a vaccine base; updating populations; regulating the positions of charging stations of the electric automobiles; and ending conditions. The immune genetic method for planning and improving the electric automobiles facing the urban distribution network adopts the fixed genetic algebra 200 as the ending condition of the algorithm, effectively improves the planning and calculating speed of the electric automobiles facing urban distribution network, and achieves the purpose of fast convergence.
