Operation Profit Model and Strategy of Electric Vehicle Battery Exchange Station in Transportation System

Electric vehicles effectively relieve the pressure on the transportation system, and can solve problems such as energy crisis and environmental pollution. However, there are 3 main problems that restrict the development and promotion of electric vehicles in current transportation system: short cruising range, long charging time and high battery purchase cost. In order to solve the above problems, this article adopts the strategy of battery exchange station and establishes an integer programming model for the operation of battery exchange station from the perspective of operators. The model comprehensively considers the exchange fee, the number of batteries, the charging and discharging capacity and the service level of the exchange station. Lingo programming technology is adopted to analyze the model. Then, the maximum value of the corresponding profit under different parameters, the number of battery charged and discharged performed by each exchange station in each time period are obtained. Meanwhile, sensitivity analysis and strategy analysis for operation profit are conducted. The results of numerical experiments show that the proposed model can minimize the operator's investment risk and maximize the operation profit, while ensuring the safe and stable output of the power grid. Therefore, it can provide a strong guidance for the operator to make a reasonable operation strategy and battery management, which is crucial for the development of electric vehicle and optimization of transportation system management.
