通过汽车运动轨迹确定充电桩使用情况：数据分析揭示充电桩运营状态

Translation: 2. Determining the usage of charging stations through car movement trajectories The location of car charging stations can be determined through the movement trajectories of electric vehicles. By analyzing the duration of car stops at certain locations, it is possible to determine whether the car is entering a charging state, whether it is using a fixed charging station or switching stations, and whether the charging is continuous or intermittent. Additionally, the charging station can be identified as 'fast charging' or 'regular charging' based on the current. The author primarily monitored the trajectory of Vehicle A as a reference and determined that the private charging stations had the highest number of charges. Furthermore, by analyzing continuous charging through switching stations, two faulty charging stations were identified. After verification, this method of determination was found to be highly accurate. This demonstrates that by analyzing the operation data of electric vehicles, the operational status and frequency of usage of charging stations can be obtained. By promoting similar methods and processing the movement trajectory data of new energy vehicles, it is possible to obtain information about the usage of charging stations, providing a data foundation for improving the spatial distribution of charging stations.'}
