Hi Dickson

here is a perfect site for SOC and SOH of li-ion batteries:

https://ti.arc.nasa.gov/tech/dash/groups/pcoe/prognostic-data-repository/

I have 7 works on this dataset. you should take glance at some of them.

Hi thank you! I had a look at the dataset you suggested. I understand there are few parameters that were recorded they are

1. Voltage

2. Current

3. Temperature

4. Capacity

How do I compute the State of Charge (SoC) from these parameters?

I intend to train a neural network to predict the SoC given the parameters.

You could read these references :

B. Saha, S. Poll, K. Goebel, and J. Christophersen, "An integrated approach to battery health monitoring using Bayesian regression and state estimation," in 2007 IEEE Autotestcon, 2007, pp. 646-653.

B. Saha and K. Goebel, "Modeling Li-ion battery capacity depletion in a particle filtering framework," in Proceedings of the annual conference of the prognostics and health management society, 2009, pp. 2909-2924.

I do not think there is a set of well validated data for your practice in the public domain. Using capacity based estimation might be not truly useful to derive SOC and SOH. I published a review article recently in J Power Sources which may help explain why:Article On state-of-charge determination for lithium-ion batteries

Hi,@Dickson Neoh

Did you try this dataset?

I am looking forward to SoC and SoH estimation of Lithium Ion battery for an EV using Machine learning. Any help in this would be really appreciable !

Really looking forward to some help in this case.

Soumyaranjan Sabat If you are looking for Lithium Ion , you can find a dataset for LiFePO4 here https://data.matr.io/1/projects/5c48dd2bc625d700019f3204

I am looking for a real data set of Li ion battery in the car. It means real test data of a car battery while car is driving. I would appreciate it.

Hi, Dickson Neoh Did you solve the problem you mentioned above about the soc estimation using current, temp, voltage, capacity?

Maybe this dataset will be useful https://data.mendeley.com/datasets/wykht8y7tg/1

" The tests can be used to test Neural Network and Kalman Filter State of Charge algorithms, or to develop battery models, and are intended to be a reference so researchers can compare their algorithm and model performance for a standard data set. "
