eflips-depot

---

Part of the eFLIPS/simBA list of projects.

---

eFLIPS has been developed within several research projects at the Department of Methods of Product Development and Mechatronics at the Technische Universität Berlin (see https://www.tu.berlin/mpm/forschung/projekte/eflips).

With eFLIPS, electric fleets and depots can be simulated, planned and designed. This repository contains only the planning and design tool for depots.

The repository contains an example for the simulation and planning of an elecric bus depot, which is based on the dissertation by Dr.-Ing. Enrico Lauth (see https://depositonce.tu-berlin.de/items/f47662f7-c9ae-4fbf-9e9c-bcd307b73aa7).

Installation

1. Clone this git repository (or download a specific release)

   git clone [e-mail]:mpm-tu-berlin/eflips-depot.git
   

2. Install the packages listed in poetry.lock and pyproject.toml into your Python environment. Notes:

   • The suggested Python version os 3.11.*, it may work with other versions, but this is not tested.
   • Using the poetry package manager is recommended. It can be installed accoring to the instructions listed here.

   macOS

   poetry env use 3.11
   poetry install
   

   Windows

   If you are using Windows, you have to provide the full path to the desired Python executable, e.g.:

   poetry env use C:\Users\user\AppData\Local\Programs\Python\Python311\python.exe
   poetry install
   

3. To start a simulation, an existing eFLIPS-Model database is requires. Once you have that, you can run the script bin/example.py

Usage

Please refer to the Documentation section of this Readme for information on how to use eFLIPS-Depot.

The API of eFLIPS-Depot can be accessed via eFLIPS.depot.api. A usage example can be found in the script bus_depot/user_example.py.

Testing

---

NOTE: Be aware that the tests will clear the database specified in the DATABASE_URL environment variable. Make sure that you are not using a database that you want to keep.

---

Testing is done using the pytest framework with tests located in the testsdirectory. To run the tests, execute the following command in the root directory of the repository:

   export PYTHONPATH=tests:. # To make sure that the tests can find the eflips package
   export DATABASE_URL=postgis://postgres:postgres@localhost:5432/postgres # Or whatever your database URL is
   export DJANGO_SETTINGS_MODULE=tests.api.djangosettings # To make sure that the tests use the correct settings
   pytest

Documentation

Documentation is available on Read the Docs.

To locally create the documentaiton from the docstrings in the code using sphinx-autoapi, you can create the documentation execute the following command in the root directory of the repository:

   cd docs/
   sphinx-build -b html . _build

Development

We utilize the GitHub Flow branching structure. This means that the main branch is always deployable and that all development happens in feature branches. The feature branches are merged into main via pull requests.

We use black for code formatting. You can use pre-commit to ensure the code is formatted correctly before committing. You are also free to use other methods to format the code, but please ensure that the code is formatted correctly before committing.

Please make sure that your poetry.lock and pyproject.toml files are consistent before committing. You can use poetry check to check this. This is also checked by pre-commit.
