batlablancaster / pybatdata

Analyse data from battery testers using Python.

pybatdata

To run the GUI: python analyseGUI.py To run from a script: python analyse.py

Modify these scripts to suit your analysis. Example data has been added to test the code.

Note than a folder pycache will be created when you run the app. However, this folder would not be tracked with the version control system.

Requirements

The code runs in Python 3 and it requires the following libraries that can be install using pip: numpy, pathlib, preparenovonix.

Contributing

If you have new analysis code add it as a function within the pybatdata/plot_cycling.py or pybatdata/plot_eis.py, depending if the type of analysis is for Cycling or EIS. Follow the example function V_I_time to see how to call the diferent functions to read the data.

If you want to enhance the code to be able to deal with a new equipment or modify the default column names, update the file pybatdata/constants.py.

Acknowledgements

The first version of this code was created by Matheus Aparecido do Carmo Alves, Alana Aragon Zulke and Caio Ferreira Bernardo, at Lancaster University. For further contributions, see the history in the corresponing GitHub.

pybatdata's Issues

README w acknowledments and examples

We need to fill in the README w some acknowledgements (in particular so the work from Alana is acknowledge, despite not having write code) and examples on how to use the code.

Deal with changes in units

Enhance the function get_column within iobat to deal with unit changes.

Integration with the matlab importer

It would be good to integrate the matlab importer routines with the visualising code here.

Structure

It would be good to re-structure the repository in a 'standard' way (something along the lines described in https://nsls-ii.github.io/scientific-python-cookiecutter/index.html): src/ (or maybe batlab_dash) for the code, docs/ for the documentation src/testing for the test_* programs to test, etc.

Not plotting

Dash environment working, data browser working (although time-consuming) but the graph is not being generated. Data is being printed in the terminal instead. when I press "plot" in the terminal you see the values picked for "cycles"

Analysis functions

Need to implement the following functions:
coulombic_efficiency.py
diff.py
DVA.py
dVdQ.py
fit_mcmc.py

into (working) functions within plot_cycling.py and then delete the above files.

Documentation

It will be good to add descriptions to the functions and routines that can be converted into some documentation using, for example Sphinx

DVA

won`t create the DVA graph for one particular data file
Errorlog I see in the terminal :

_cycles: []
Differential Voltage Analysis (DVA)
C:\Users\zulke\PycharmProjects\batlab_dash-master\batlab_dash-master\Novonix_Protocol.py:129: RuntimeWarning:

divide by zero encountered in divide_
👍

Browsing data issue

Issues when selecting the .csv file. It doesn`t upload on the screen. In the terminal one reads:
TypeError: a float is required

Add the option to define the name for the output figures

When plotting, give the option to set a name and path to save figures.

Testing

It will be good to include some testing and maybe even some continuous integration.

Read raw data

Read raw files for both Novonix and Basytec
