Lithium Battery SOC Estimation and Monitoring System Based on LabVIEW

文中介绍了一种采用LabVIEW设计和实现的锂电池参数监测与剩余电量(SOC)在线估计的硬件系统。该锂电池监测系统主要功能包括:采集锂电池处于工作状态下的电流、电压参数,显示并存储该参数信息,通过已经求得的精确锂电池模型对SOC进行在线估计并实时显示。将锂电池恒流放电与变流放电时的实验结果与真实值进行比较,验证了该系统参数采集与SOC估计的有效性与精确性。

This paper introduces a hardware system based on LabVIEW and built for lithium battery parameter monitoring and State Of Charge （SOC） online estimation. The module of the system includes three parts： the acquisition module monitors the real -time current and voltage of the battery ceils; the data processing module stores and displays data; the control module calculates the SOC with the accurate battery model. Through the comparison of experimental results of constant - current discharge and variable - current discharge on lithium battery with the real value of the battery, the validity and accuracy of the battery monitoring system are verified.
