Abstract: The electric vehicle（EV） charging facilities are not well developed currently and cannot meet the special charging demands of users such as emergency, short-time, and convenient charging and diversified charging scenarios. This paper proposes an emergency charging scheme combining precise distribution and facility layout optimization to meet the EV demands of emergency charging, scattered charging in remote areas, and the short-term convenient power supply. This scheme coordinates with charging stations to form an optimized EV charging network. Considering the travel rules, driving rules, and driver charging decisions of EVs, the spatial and temporal distribution of emergency charging demand is predicted. By using the distribution services, considering the distribution of existing charging stations, an emergency charging facility layout model with the lowest user waiting cost and construction and operation cost is established. Finally, the case analysis shows that, after the layout planning, the added charging facilities form a new charging network with the original charging facilities and re-simulate the electric vehicle travel process, and the emergency charging demand satisfaction rate reaches 98.15%.
