Ampere - Advanced Model Package for ElectRochemical Experiments

`Ampere` is a Python module for working with battery models.

Using a [scikit-learn-like API](, we hope to make visualizing, fitting, and analyzing impedance spectra more intuitive and reproducible.

<i>Ampere 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]( or, better yet, make the code improvements and [submit a pull request](! The goal is to build an open-source tool that the entire electrochemical community can improve and use! 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 requires:

- Python (>=3.5)
- SciPy (>=1.0)
- NumPy (>=1.14)
- Matplotlib (>=2.0)
- Cython

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 Ampere is using pip:

`pip install ampere`

#### Examples and Documentation

Several examples can be found in the `examples/` directory (the [fitting_tutorial.ipynb]( is a great place to start) and the documentation can be found at [](
