The planning of electric vehicle charging stations needs to consider not only the cost of connecting to the power grid but also the convenience of electric vehicle users, as well as the impact of traffic congestion on user travel. Based on the spatial and temporal distribution characteristics of electric vehicles, an electric vehicle spatial?temporal distribution model is established. The impact of traffic congestion on the travel characteristics of electric vehicle users and the selection of charging stations is fully considered, and the electric vehicle entry capacity is calculated at different times. A mixed?integer second?order cone programming model is established to minimize the total investment cost, total operating cost, and total user travel cost, taking into account the impact of traffic congestion on electric vehicle charging station planning. The effectiveness and feasibility of the proposed method for planning electric vehicle charging stations considering traffic congestion are verified through hypothetical planning areas.
