基于电动汽车充电站监控管理系统的并发仿真测试

摘要

A concurrent testing method for large scale simulation testing of electric vehicle charging station integrated performance monitoring and management system in a real environment was proposed. The test was achieved by developing a simulation program of AC/DC charging pile, and communicating with system by UDP (User Datagram Protocol). The test results showed the changing trend of the monitoring response time, history query response time and CPU usage of system along with the increasing number of charging piles. It provided the basis for system performance evaluation. Simultaneously, the result also gave the evident that the method was feasible for the large scale simulation of concurrent testing of electric vehicle charging stations monitoring and management system performance.%为测试电动汽车充电站监控管理系统在真实环境下的综合性能，提出1种电动汽车充电站管理实时监控系统的并发仿真测试方法。该方法通过开发仿真充电桩程序来模拟交直流充电桩，采用UDP（User Datagram Protocol，用户数据报协议）通信协议与电动汽车充电站管理系统实现通信，进行大规模充电桩集群监控管理测试。测试结果给出了系统的实时监控响应时间、历史查询响应时间以及CPU使用率随充电桩数量增加的变化趋势，为进行系统性能综合评价提供了依据。同时，通过试验验证了该方法在充电站管理系统并发测试中应用的可行性。
