fuzzy-exi-generator

This is a small fuzzy generator. It generates exi streams and matching json files for DIN70121, ISO15118-2 and -20 messages. It uses the message definition from the iso15118 project (https://github.com/EcoG-io/iso15118).

Efficient XML Interchange (EXI) is a very compact representation for the Extensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources

-- Efficient XML Interchange (EXI) Format 1.0 (Second Edition) 1

With this generator it is possible to generate thousands of different exi streams and matching json files to test EXI codec libraries. The DIN and ISO messages do not make sense for a charging process, but are still valid EXI streams that comply with the XSD.

Usage

Install the necessary python packages using

python3 -m pip install -r requirements.txt

Use the following command to generate the exi streams and json files

python3 src/main.py

You can find the generated data in the output folder, saved as .csv files.

You can change the number of generated messages using the arguments

python3 src/main.py ---number-sap-msgs 5 --number-din-msgs 25 --number-iso2-msgs 40

Status

The current generator status is described here, which messages can currently be generated.
