关于您的，Improved_EKFSim.slx，文件中我想请教一下您的电池模型是Thevenin模型吗？还是其他的电池模型？
希望得到您的解答。

请问为什么要对电流值做*1.5/50的操作呀，50是安时容量，但是为什么要这么处理

Hi, I am trying to make a 2RC equivalent circuit model using your EKF model. What changes do I need to make in order to run the simulation successfully?. Any help would be appreciated. Thank you.

Hi~Thanks for sharing!
As a beginner, I am just starting to learn about SOC estimation and parameter identification related to it, and I am not yet able to understand the whole model you provided. Can you recommend any tutorials at an introductory level, preferably one where I can build simulink and code from scratch, appreciated! :D

how are you
Please give me your full name if possible
And the title of the paper about this work
This is all for the citation
Thank you waiting for your reply

我想要使用您的开源项目，想私下里交流一下，但是没找到您的联系方式。我的邮箱：[email protected]
谢谢！

这组电池数据是您自己测得还是下载的数据呢，请问是否可以分享呢，谢谢

Hello Mr Walter,

I am currently working on a BMS and therefore find your work very relevant.
While I was working on your work I noticed that you used functions in Improved_EKFSim.slx to describe the battery parameters like r0 or cp.
I would like to know how you came across these functions.
Secondly I tried to plot ro and came across this picture (see appendix). I find it a bit strange that the internal resistance increases with increasing SOC. Because as far as I know, the battery gets a better conductivity with increasing state of charge (SOC).
I would like to take this opportunity to thank you for this great work and would be glad about your feedback.

With kind regards

Dear Authors,

Thank you very much for this work. I have seen the other issues however, there were no clear information about the details of the model.

Here are my questions if you may answer:
1-Why do u multiply your current values with some constants? you had 50 Ah battery so I try to see a point however I could not understand well.
I= -(current.data)' *1.5 / 50;

2-If I use battery data for 450 V (respectively higher current values) why the simulation gives wrong values? Here are some snapshots. I updated the capacity value....

3-Are the C0, R or other formulations battery dependent? If yes, how can I find my own formulation or parameters?

Thank you

程序中貌似认定通过状态空间方程预估得到的soc为真实值，且在AH、EKF、UKF的Error计算中使用SoC_real作为基准值。
请问这一做法的依据是什么？
如果通过状态空间方程预估得到的soc为真实值，那么为什么需要AH、EKF、UKF一系列方法呢？

我想请教一个问题：在我看的文献中，EKF算法会用到SOC的初始值，我研究了您的仿真，我能力很差，没有找到初值的设置在哪，请问可以加一下您的联系方式再详细的沟通一些吗，谢谢！！！

How to change the initial SOC value in simulink model ?....I just want to check the convergence of EKF model

你好！
我在修改Imporved_EKFSim.slx文件时，将模型的采样频率设置为fixed-step，并同时把采样周期改为0.1s和0.01s跑了一下simulink模型（同时也改了模型中的tr参数和一些延迟模块的采样周期以适配），此时我发现采样周期为0.1s和0.01s的实际SOC值相差有些大，想向你请教一下原因：
采样周期0.1s：

采样周期0.01s：

非常感谢！

when I am running file its showing flowing

Error in EKF_UKF_Thev (line 13)
States_upd = [SoC_upd_init;0]; % Estimated initial state(SoC_upd, Up_upd)

Hi AlterWL,
Can you share with me from where you have found these equations to model?
Your work is of great information, very clear compared to many other papers.
Please can you share information from where you have taken these equations as well as if you could share the functions you have used in the thevenin model and the EKF model?
I am still not clear on the UKF so if you could give me all the data you can on these would be of great help for me.
I have about 21 errors running my data on this can you help me?

Looking to hear from you soon.
Thanks in advance,
Nikhil Supreeth
