Presentation

This project implements the 15118-20 norm for the use case DC BPT Dynamic using Python.

Installation and configuration

To install the tool, it is fairly straightforward:

  1. Download the git repository <https://gitlab.pleiade.edf.fr/R43/15118-20-v2g> and Miniconda <https://docs.conda.io/en/latest/miniconda.html>
git clone https://gitlab.pleiade.edf.fr/R43/15118-20-v2g
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
  1. Setup a virtual environment
conda create -n edf15118-20 python=3.8
  1. Install dependencies
pip install -r requirements.txt // using pip
conda install -f environment.yml // using conda
  1. Configure the tool by modifying the .ini files.

Usage

Launching protocol

  1. Set up the network settings (ports, interfaces, ChargeController,...)
  2. Connect to serial terminals using screen
  3. On the EVCC Charge Controller card, run to launch the driver:
sh start_server.sh // to have the logging on scree
systemctl start tcpserver.service // to have it on background
  1. Start the EVSE, then the EV
  2. Plug the cables

GUI

python secc/evse_gui.py // run evse
python secc/ev_gui.py   // run ev

To stop running, use the stop button on the EV side.

Log-based

python secc/start_evse.py // run evse
python secc/start_ev.py   // run ev

To stop running, press ENTER on the EV side in the terminal.

Extras

Generating documentation

To generate the documentation, go to doc and run:

make html

Updating XSD files and associated XML classes

To update the XSD files and the associated XML classes:

  1. Make a backup of the old XSD files in shared/xsd_files/previous_version
  2. Make a backup of the old EXIG files as well in shared/exig_files/previous_version
  3. Copy the new XSD files in shared/xsd_files/latest_version
  4. Generate the new EXIG files using OpenEXI_Example4/OpenEXI_Example4.jar
  5. Copy the new EXIG files in shared/exig_files/latest_version
  6. Delete shared/xml_classes package
  7. Generate the new XML classes:
xsdata shared/xsd_files/latest_version/V2G_CI_AppProtocol.xsd --package shared.xml_classes.app_protocol
xsdata shared/xsd_files/latest_version/V2G_CI_CommonMessages.xsd --package shared.xml_classes.common_messages
xsdata shared/xsd_files/latest_version/V2G_CI_DC.xsd --package shared.xml_classes.dc

Generating new certificates

To generate new certificates, go to shared/certificates/ and run:

./generateCertificates.sh

Updating packages

To update all pip packages, run:

pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

Exporting dependencies

To export dependencies, run:

pip freeze > requirements.txt // using pip
conda env export > environment.yml // using conda
