【摘要】：近年来,随着自然资源日益枯竭和环境地恶化,节能减排便成为当前汽车工业发展必须要考虑的因素。在这种情况下,新能源汽车尤其是电动汽车便成为了世界各国普遍关注的焦点。动力电池总成作为电动汽车最重要的核心部件,它的测试作为其生产过程中的重要环节,是保证动力电池总成零部件状态一致性、电控系统功能完整性的重要保障。因此,研究开发出一套动力电池总成检测系统也就显得很有必要。本文针对的是本人所在实习单位的新能源汽车动力电池生产领域,设计一套动力电池总成在生产下线过程中的自动检测系统。首先分析了电池总成检测系统的研究原理及方法,给出了检测系统的功能需求,并根据不同的功能需求,设计出了功能检测项,详细阐述了各项功能的检测要求和评判标准。其次搭建了检测系统的结构框架,设计了检测系统的CAN总线通信协议,通过CAN总线发送测试命令,读取电池总成系统的数据信息,根据各项检测功能的需求,完成相应信号的数据信息采集,得到检测项的测试结果。最后根据检测功能项设计开发出上位机软件,系统软件具有良好的人机交互界面,测试进程实时显示,主控计算机自动对检测结果数据进行分析处理,通过打印机以报表的形式自动打印出来,同时通过网关将测试结果发送至终端服务器上进行存储及显示,为实际的生产使用提供了较大的便利。本套系统实现了对动力电池总成零部件状态、电控系统功能的集成检测,测试数据及结果真实准确,电池总成系统的检测保证了电池总成产品的质量。
[Abstract]:In recent years, with the depletion of natural resources and the deterioration of the environment, energy saving and emission reduction have become the factors that must be taken into account in the development of automobile industry. Under such circumstances, new energy vehicles, especially electric vehicles, have become the focus of attention all over the world. As the most important core component of electric vehicle, the test of powerbattery assembly, as an important link in its production process, is an important guarantee to ensure the state consistency of power battery assembly parts and the functional integrity of the electronic control system. Therefore, it is necessary to study and develop a set of power battery assembly detection system. Aiming at the new energy vehicle power battery production field of my practice unit, this paper designs a set of automatic detection system of power battery assembly in the process of production and off-line production. Firstly, the research principle and method of battery assembly testing system are analyzed, and the functional requirements of the testing system are given. According to the different functional requirements, the functional detection items are designed, and the testing requirements and evaluation criteria of each function are described in detail. Secondly, the structure of the detection system is set up, and the communication protocol of CAN bus is designed. The test command is sent through the CAN bus, the data information of the battery assembly system is read, and according to the requirements of each detection function, Complete the data acquisition of the corresponding signal, and get the test result of the test item. Finally, the upper computer software is designed and developed according to the test function item. The system software has a good human-computer interaction interface, the test process is displayed in real time, and the main control computer automatically analyzes and processes the data of the test result. The test results are sent to the terminal server for storage and display by means of the printer and the test results are sent to the terminal server for storage and display, which provides great convenience for the actual production and use. The system realizes the integrated testing of the parts and components of the power battery assembly and the functions of the electronic control system. The test data and results are true and accurate. The inspection of the battery assembly system ensures the quality of the battery assembly products.
