摘要
系统为工控机结合微处理器的双层分布式控制结构,采用脉冲宽度调制技术的充放电方式,运用闭环负反馈的控制策略。主要介绍了锂电池性能检测控制系统的总体设计方案,锂电池充放电控制模块、信号采集控制模块等设计。最后给出了系统的实验结果及数据分析。结果表明,该系统响应快、精度高,运行稳定可靠,操作方便,能够根据标准的要求进行程序设定,完成多种工步的检测。
The system used IPC and micro processor as the core of the double layer distributed control structure,combined with the closed-loop negative feedback control strategy and PWM charging and discharging method. Theoverall design scheme of lithium battery performance testing system,and the design of battery charging anddischarging control module,signal acquisition module and so on were mainly introduced. Finally,the experimentalresults and data analysis of the system were given. The results show that the system has fast response and highprecision. The system is stable and reliable,and the operation is convenient. It could be set according to therequirements of the standard,and complete a variety of industrial processes to detect.
