Optimal Scheduling of Batteries for Electric Vehicle Battery Swapping Stations in Beijing

. With the increasing global concern for environmental protection and sustainable development, electric vehicles have become the main development trend in urban transportation. Research on the optimization of battery scheduling for electric vehicle battery swapping stations in Beijing is of great significance for improving the operational efficiency of electric vehicles and reducing carbon emissions in urban transportation. This paper analyses the current situation of electric vehicle battery swapping stations in Beijing, takes the maximum operating profit as the optimization objective, establishes a battery charging and discharging scheduling model considering time-sharing tariffs, and solves the optimal battery scheduling scheme for a certain battery swapping station in Beijing as an example. The results show that the main factors affecting the operating profit of Beijing's battery swapping stations are the service charge and battery ownership. The batteries in the battery swapping stations are not always recharged during tariff-flat hours but are flexibly adjusted within the limits of switching demand and the number of devices. Optimizing the battery utilization and charging/discharging process by taking advantage of the peak-to-valley difference in Beijing's electricity price can effectively reduce the operating cost of the battery swapping station and help to balance the load of the power grid and reduce the pressure at peak hours, thus providing a powerful guide for the development of reasonable and effective operation strategies and battery charging/discharging management for battery swapping stations in Beijing.
