Equivalent circuit model
This repository contains Python code for running an equivalent circuit model (ECM) developed for a 2013 Nissan Leaf battery cell and module. The ecm
package contains source code for the equivalent circuit model while the examples
folder provides scripts for running the ECM for a battery cell, module, and pack. Model parameters are determined from hybrid pulse power characterization (HPPC) and discharge tests conducted at ORNL. The battery cell and module specifications were provided by NREL.
Installation
The Anaconda or Miniconda distribution of Python 3 is recommended for this project. The ecm
package requires Matplotlib, NumPy, Pandas, and SciPy.
The simplest way to install the ECM package is with pip. This can be done from within the equiv-circ-model directory:
# Install the ecm package
pip install -e .
A requirements file is provided for running the ECM in a virtual environment using pip:
# Create a new virtual environment
python -m venv env
# Activate the environment
source env/bin/activate
# Install packages needed for the ECM
pip install -r requirements.txt
# From within equiv-circ-model directory, install the ecm package
pip install -e .
# Deactivate the environment
deactivate
# Remove the environment by deleting the `env` folder
An environment yaml file is also provided for running the ECM in a conda environment:
# Create a new conda environment and install packages needed for the ECM
conda env create -f environment.yml
# Activate the environment
conda activate ecm
# From within equiv-circ-model directory, install the ecm package
pip install -e .
# Deactivate the environment
conda deactivate
# Remove the environment and its installed packages
conda env remove -n ecm
Usage
Examples of using the ecm
package are provided in the examples
folder. Examples are organized into subfolders for battery cell and battery module models. From within the subfolder, each script can be run from the command line such as:
# View plots of the battery cell HPPC data
cd ~/equiv-circ-model/examples/cell
python view_hppc_data.py
# Run the ECM for a battery cell and compare to HPPC battery cell data
cd ~/equiv-circ-model/examples/cell
python hppc_vt.py
