摘要
以锂离子电池作为研究对象分析了多种电池等效电路模型的优缺点,最终选取二阶RC等效电路模型,搭建了仿真模型。该模型很好地表现了电池的输出特性,不仅直观地反映了开路电压(Open Circuit Voltage,OCV)-荷电状态(State of Charge,SOC)特性,更进一步反映了工作电压-荷电状态特性,对电池的SOC在线评估具有的重要作用。
Taking lithium-ion battery as the object of study, the advantages and disadvantages of various cell equivalent circuit mode are analyzed. Eventually, the second order RC equivalent circuit model is selected to build the simulation model. The model shows very well the output characteristics of the battery, not only intuitively reflects the open circuit voltage -state of charge characteristics, but also reflects the working voltage -state of charge characteristics. It plays an important role in online SOC evaluation of batteries.
