摘要
由于社会和环境的需求,电动汽车市场规模不断扩大,对车用电池的研究也在不断加深。其中,电池模型的研究起着十分关键的作用,它关系到电池系统对SOC、SOH、工作参数曲线等信息的描述准确与否,进而关系到相关控制策略的执行,影响整车的参数和性能。文章介绍了三类电池模型——简化电化学模型、等效电路模型和神经网络模型。简化电化学模型采用数学方法描述电池内部的反应过程,等效电路模型使用电路网络模拟电池动态模型,神经网络模型是利用人工智能的方法模拟电池的运行。神经网络非线性、多输入多输出、泛化能力强的特点,尤为有利于描述电池这一高度非线性系统,是研究和应用的重点。
As the requirement of society and environment,the scale of electronic vehicle market increase,and so does the research of battery.The research of battery model plays a key roel role among this.because it has a strong relationship with the accuracy of the description of SOC,SOH and running parameter bight.Forthermore,it relates to the execution of relative control strategy and vehicle parameter and function.This passage introduces 3 battery model——simplied electrochemical model,equivalent circuit model and NNs model.Simplied electrochemical model describes reaction in the battery using math tools,equivalent circuit model simulates dynamic model by electric circuit and NNs model stimulates work of battery using artificial intelligence.Unlinear,multiply-inputed,multiply-outputed and generalized NNs is specially fit for describing quite unlinear system—battery.so it is a key point for researching and applying.
