The V2G Viewer Pro© opens pcap/PcapNg files and displays the High Level Communication (HLC) data, that have been exchanged between the EV and EVSE. (EXI)

Pcap/PcapNg files can, for example, be recorded by Wireshark or the PLC-Tracer© and be imported to the V2G Viewer Pro©.




The data packages are then, if applicable, extracted and all HLC-Data is being displayed. The by the PLC-Tracer© recorded PWM values are also being displayed.

Furthermore the file is being checked for inconsistencies regarding the most recent ISO 15118 and DIN 70121. In case of a detection of an inconsistency, a warning or error message is being displayed by the interpreter. All displayed packages can be exported as a CSV-file (readable by e.g. Microsoft Excel)

Furthermore a graphic (png, jpg, bmp) displaying the charging cycle can be created. The advanced search function makes for an easy search for messages and their contents.




The collected messages in the interpreter can be exported as an XML file. For seamless operation in existing systems, the V2G Viewer Pro© can be thoroughly operated by command line.
