摘要
Abstract
In order to better evaluate the performance and lifespan of batteries,an equivalent model of lithium batteries is firstly established.By establishing appropriate circuit models,the dynamic and electrochemical characteristics of lithium batteries can be better understood,thus enabling better design and control of battery systems.Recursive least squares method is used to identify model parameters.By parameter identification,the electrochemical and diffusion characteristics of lithium batteries can be obtained to further evaluate and optimize the performance and lifespan of the battery system.In order to verify the correctness of the established model and parameter identification results,a simulation model of the battery is built using MATLAB/Simulink simulation software.After establishing the simulation model of the battery,the measured voltage values are input into the simulation model for simulation,and the accuracy of the model is verified by comparing the simulated voltage values with the measured voltage values.The experimental results show that this method can provide a theoretical support for the management and control of lithium-ion batteries,and provide more accurate and reliable support for their applications.关键词
