基于LabVIEW的动力电池SOC实时估算系统研发
Research on real-time estimation system of power battery SOC based on LabVIEW
摘要
Abstract
In the study of electdc vehicle energy control strategy and battery management system,it is important and difficult to accurately estimate the battery state of charge (SOC).Based on the working principle of lithium iron phosphate power battery and charge and discharge characteristic test,MATLAB software was used to obtain the coulomb efficiency at different discharge currents and the relationship between open-circuit voltage and SOC.And also the LabVlEW virtual instrument and the related hardware were adopted to collect the related real time data of power battery,and the Ah counting strategy and open circuit voltage method were combined to estimate the SOC,which realize the real-time SOC estimation of power battery with high precision and improve the practicality and accuracy of the battery SOC system.关键词
