摘　　要：为了满足电动汽车牵引电机系统性能测试的需要,针对电动汽车牵引电机系统的工作特点,建立了电动汽车动力性能试验台架,开发了利用虚拟仪器技术的测试系统软件,设计了相应的控制策略,实现了多路并行、高速数据采集的结果。测试系统充分发挥了虚拟仪器技术灵活性、兼容性强和可重用度高的特点。在测试平台上对国内外多台电动汽车牵引电机的动力特性进行了测试,并完成了多组电动汽车用动力锂离子电池组的放电试验。结果表明,建立的基于虚拟仪器的测试系统在实际应用中提高了测试过程的客观性和自动化程度,具有较好的科研价值和应用前景。In order to satisfy the performance test requirements of driving motor system of electric vehicle,a platform to test electric vehicle dynamic performance is established based on driving motor characteristic. Virtual instrument technology is used in the development of test system software and corresponding control strategy is designed. The test system makes full use of the flexibility,compatibility and reusability of virtual instrument and can realize multi-channel parallel high speed data acquisition in motor test. The platform can meet the test needs of electric vehicle driving motors and power battery packs. The result shows that the test system is used in practical experiment successfully,objectivity and automation in test process are improved remarkably,and test system has preferable value in technique research and application.
