The invention provides a charging station charging strategy optimization method based on an improved NSGA-II algorithm, and belongs to the technical field of multi-objective optimization. The problem of operation cost of an electric heavy truck battery swap station in a battery swap mode is solved; comprising the following steps: modeling an actual operation scene of the electric heavy truck in a battery swap mode, and determining the daily average battery swap demand of a battery swap station; taking the minimization of the operation cost of the battery swap station as a target, providing three target functions including the initial configuration battery number of the battery swap station, the battery charging loss and the electric power cost, and establishing a multi-target optimization model; the aspects of operator operation, parameter adjustment, crowding degree distance calculation and the like in a traditional NSGA-II algorithm are improved, and an established multi-target optimization model is solved, so that a charging and battery replacing strategy of the heavy truck in a battery replacing mode is obtained; the method is applied to the operation of the battery swap station of the electric heavy truck.
