纯电动公交车电驱动系统调试与分析

    Debugging and Analysis of Electric Drive System of Pure Electric Bus

    • 摘要: 近年来由于国家政策和地方的大力扶持,新能源汽车行业发展迅猛,纯电动公交车在市场上越来越普及,在实际生活中出现的频度也越来越高。为了保证车辆性能及人员安全,现场安装调试就变得关键,这就需要相关从业人员具备一定的知识储备和实际动手能力,通过检查安装、采集CAN报文的手段,排查车辆潜在问题,保证车辆在运行中稳定。根据实际调试车辆中的工作经验,就低压电源测试、通信检测、高压测试、动态测试、NVH测试五个方面进行讨论分析,把纯电动公交车调试过程存在的问题分析讨论,以保证纯电动车辆能够安全、可靠、舒适的运行。

       

      Abstract: In recent years, due to national policy and local support, the new energy vehicle industry has developed rapidly, and pure electric buses have become more and more popular in the market, and the frequency of appearance in real life has also increased. To ensure vehicle performance and personnel safety, on-site installation and debugging is particularly critical, which requires relevant practitioners to have a certain knowledge base and practical hands-on ability to check the installation and collect CAN messages using the vehicle to troubleshoot potential problems and ensure that the vehicle is stable in operation. This paper discusses and analyzes the five aspects of low-voltage power testing, communication testing, high-voltage testing, dynamic testing, and NVH testing based on the experience of working in debugging vehicles, and analyzes and discusses the problems that exist in the debugging process of pure electric buses to ensure that pure electric vehicles can operate safely, reliably and comfortably.
