摘　　要：为了提高蓄电池组运行状态在线诊断能力,该文通过核容装置拓扑模型对不同型号的蓄电池进行检测,利用直流屏完成电池信号的控制。建立蓄电池运行工况结构,利用积分控制的方式对其参数特性进行修正。运用变分模态分解(variational mode decomposition,VMD)算法进行模态数据解析和统计,并实现电池放电波形扰动的平复控制。通过Proteus软件仿真系统诊断过程,结果是提高了在线诊断能力,实验表明该设计采用的GM-100铅酸电池组的额定容量最大为120.0 Ah,最大放电量达到108.3 Ah,诊断数据平均精度为98.6%,该研究为其他技术研究奠定了技术基础。In order to improve the on-line diagnosis capability of the battery pack operating status,the technical solution adopted is to detect different types of batteries through the topological model of the nuclear capacity device,and use the DC screen to control the battery signal.Establish the battery operating condition structure,and modify its parameter characteristics by means of integral control.VMD(variational mode decomposition)algorithm is used for modal data analysis and statistics,and the smooth control of battery discharge waveform disturbance is realized.Through the Proteus software to simulate the system diagnosis process,the result is to improve the online diagnosis ability.The experiment shows that the GM-100 lead-acid battery pack used in this design has a maximum rated capacity of 120.0 Ah,a maximum discharge capacity of 108.3 Ah,and an average diagnostic data accuracy of 98.6%,this research has laid a technical foundation for other technical research.
