# V2Gdecoder
V2Gdecoder is a tool aimed to encode and decode V2G messages that commonly use EXI to compress exchanged XML files between a car Power-Line Communication module and a charging station.
This tool is based on [RISE V2G shared library](https://github.com/V2GClarity/RISE-V2G) to easily parse messages.
How to use

```
### Using the web service
The tool can be runned as follows:
```
$ java -jar V2Gdecoder_test.jar
```
You can then use your favorite tool/interpreter to send EXI data to get the reply as follows:
