A Python package for working with battery discharge data
[![Documentation Status](https://readthedocs.org/projects/impedancepy/badge/?version=latest)](https://impedancepy.readthedocs.io/en/latest/?badge=latest) –>
battery is a Python module for working with battery models.
Using a [scikit-learn-like API](https://arxiv.org/abs/1309.0238), we hope to make visualizing, fitting, and analyzing impedance spectra more intuitive and reproducible.
<i>impedance.py is currently in the alpha phase and new features are rapidly being added.</i> If you have a feature request or find a bug, please feel free to [file an issue](https://github.com/ECSHackWeek/impedance.py/issues) or, better yet, make the code improvements and [submit a pull request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/)! The goal is to build an open-source tool that the entire impedance community can improve and use!
impedance.py currently provides: - a simple API for fitting, predicting, and plotting impedance - equivalent circuit fitting with customizable models - convenient Nyquist plots including confidence interval estimation for fit circuits
several features are currently being improved upon: - implementation of measurement models as a data validation method - interactive plotting with altair - adding more impedance elements - physics-based impedance models for lithium-ion batteries
### Installation #### Dependencies
- Python (>=3.5)
- SciPy (>=1.0)
- NumPy (>=1.14)
- Matplotlib (>=2.0)
Several example notebooks are provided in the examples/ directory. Opening these will require Jupyter notebook or Jupyter lab.
#### User Installation
The easiest way to install battery.py is using pip:
pip install battery
#### Examples and Documentation
Several examples can be found in the examples/ directory (the [fitting_tutorial.ipynb](https://github.com/ECSHackWeek/impedance.py/blob/master/examples/fitting_tutorial.ipynb) is a great place to start) and the documentation can be found at [impedancepy.readthedocs.io](https://impedancepy.readthedocs.io/en/latest/).
