liionpack takes a 1D PyBaMM model and makes it into a pack. You can either specify the configuration e.g. 16 cells in parallel and 2 in series (16p2s) or load a netlist.
Follow the steps given below to install liionpack. The package must be installed to run the included examples. It is recommended to create a virtual environment for the installation, see the documentation.
To install liionpack using pip, run the following command:
pip install liionpackThe following terminal commands are for setting up a conda development environment for liionpack. This requires the Anaconda or Miniconda Python distribution. This environment installs liionpack in editable mode which is useful for development of the liionpack source code. General users should install liionpack with pip.
# Create a conda environment named lipack
cd liionpack
conda env create --file environment.yml
# Activate the environment
conda activate lipack
# Exit the environment
conda deactivate
# Delete the environment
conda env remove --name lipackIn order to use the draw_circuit functionality a version of Latex must be installed on your machine. We use an underlying Python package Lcapy for making the drawing and direct you to its installation instructions here for operating system specifics.
The following code block illustrates how to use liionpack to perform a simulation:
import liionpack as lp
import numpy as np
import pybamm
# Generate the netlist
netlist = lp.setup_circuit(Np=16, Ns=2, Rb=1e-4, Rc=1e-2, Ri=5e-2, V=3.2, I=80.0)
output_variables = [
'X-averaged total heating [W.m-3]',
'Volume-averaged cell temperature [K]',
'X-averaged negative particle surface concentration [mol.m-3]',
'X-averaged positive particle surface concentration [mol.m-3]',
]
# Heat transfer coefficients
htc = np.ones(32) * 10
# Cycling experiment, using PyBaMM
experiment = pybamm.Experiment([
"Charge at 20 A for 30 minutes",
"Rest for 15 minutes",
"Discharge at 20 A for 30 minutes",
"Rest for 30 minutes"],
period="10 seconds")
# PyBaMM parameters
parameter_values = pybamm.ParameterValues("Chen2020")
# Solve pack
output = lp.solve(netlist=netlist,
parameter_values=parameter_values,
experiment=experiment,
output_variables=output_variables,
htc=htc)There is a full API documentation, hosted on Read The Docs that can be found here.
