Installation on Windows10
-
Install python (windows automatically launches the installer if you type „python“ into the search field of the task bar)
-
Install Wireshark, this includes the pcap driver, which is necessary for low-level-network-interaction
-
Install git (recommended, but not necessary if you get the sources from git on an other way, e.g. via zip download)
-
Install mingw32 (if not included in the git installation)
-
Install python libraries Attention: There are (at least) three different python-libs available for pcap:
- Libpcap
- Pylibpcap (But: only Python2)
- Pypcap (recommented on https://stackoverflow.com/questions/63941109/pcap-open-live-issue)
- Pcap-ct (https://pypi.org/project/pcap-ct/) We use the last one. python -m pip install --upgrade pcap-ct This is fighting against the Libpcap-installation, so we need to deinstall the second: python -m pip uninstall libpcap Then again install pcap-ct, and finally add in the libpcap_platform__init__py the missing is_osx = False. (Is in the meanwhile fixed in the github repository.)
- Clone the two github repositories, and compile the OpenV2Gx EXI decoder/encoder: Create or use a folder, where you want to store the tools, e.g. C:\myprogs\ and open a command prompt there.
git clone http://github.com/uhi22/pyPlc
git clone http://github.com/uhi22/OpenV2Gx
cd OpenV2Gx\Release
mingw32-make all
(this may take some minutes)
Test the EXI decoder/encoder
cd myprogs\OpenV2Gx\Release
OpenV2G.exe DD809a0010d0400000c800410c8000
OpenV2G.exe EDB_5555aaaa5555aaaa
This should run without error and show the decoded/encoded data in the command window.
Now we go to the python part.
cd $home/myprogs/pyPlc
Check python version
python --version
reports e.g. 3.9.2.
-
Edit the configuration file The file pyPlc.ini can be changed in a way to fit the needs. E.g. the default behavior (PevMode or EvseMode) can be configured, for the case that the pyPlc script is called without command line arguments.
-
Edit the MAC of the network interface (Not clear, whether this is still needed. Todo: optimize code and description...) Find out the MAC address of the laptops ethernet interface, by running
ipconfig -all
in the command line. Edit the file addressManager.py and write your MAC into the MAC_LAPTOP variable. -
Perform a simulated charging session Open two command line windows. In one command line, start the charger (EVSE) in simulation mode:
python pyPlc.py E S
. In the other window, start a car (PEV) in simulation mode:python pyPlc.py P S
. Each of it should show a window where we can see how the charging works. -
Perform a real charging session If you have set the intended mode in the pyPlc.ini, simply call
python pyPlc.py
.
Driver for the USB-to-Serial brigde
(This is optional and only necessary, if devices like Dieter or display is planned to be used on a USB-to-serial converter.) For the USB-to-Serial bridge, which is sold as CP2102, the Windows 10 tries to install the driver when plugged-in. But the device did not work together with the driver which windows found automatically. A root cause may be, that the device is not an original CP2102, but a clone. Finally found a driver on https://www.pololu.com/docs/0J7/all, which works.
