Can you add your mat to csv convertor? #1

I researched a lot but NASA battery dataset does not contains any SoH or actual capacity value, can you share any code about NASA matlab file to your csv format i need only this, because I want to train LSTM with all NASA battery dataset values.

Sorry for the late reply. The csv dataset I used was provided by a competition and uploaded to GitHub. But we can make this dataset ourselves enough.

You can download "5. Battery Data Set" from this website and calculate SOH values using this dataset. Please refer to README.txt in this dataset and presentation uploaded to my GitHub.

thank you!

Hello! I'd like to ask as well if you can explain how you got the state of health into your data set. The data set provided by NASA describes all of the traits you list in your data except for SOH. Then, you suddenly have a csv with a SOH column. How did you calculate SOH? In your README you link to the code, wherein you just load the data set that includes the SOH. How did you create those?

Thanks so much! Overall, your repo is very helpful!

Please understand that I cannot send you SOH data because it is the data that I received privately. As shown in presentation in readme file, SOH is calculated as (battery discharge charge at m-th cycle)/(initial battery discharge charge (2Ah)). Each can be obtained from NASA's PCoE Dataset. I'm sorry that I couldn't prepare the English version of presentation :) Thank you for your interest to my repo. 👍🏻
