Goal of the fork

Command line interface to decode and encode EXI data

e.g. $ ./OpenV2G.exe DH8000dbab9371d3234b71d1b981899189d191818991d26b9b3a232b30020000040040 should Decode the ApplicationHandshakeRequest.

e.g. $ ./OpenV2G.exe EDi_380_20 should Encode with DIN schema the CurrentDemandResponse with 380V and 20A

The result is provided on stdout in JSON format, e.g.

	$ ./OpenV2G.exe DD809a001150400000c80006400000
	{
	"msgName": "PreChargeReq",
	"info": "14 bytes to convert",
	"error": "",
	"result": "",
	"schema": "DIN",
	"g_errn": "0",
	"header.SessionID": "",
	"header.Notification_isUsed": "0",
	"header.Signature_isUsed": "0",
	"DC_EVStatus.EVReady": "0",
	"DC_EVStatus.EVErrorCode": "0",
	"DC_EVStatus.EVRESSSOC": "0",
	"EVTargetVoltage.Multiplier": "-1",
	"EVTargetVoltage.Unit": "5",
	"EVTargetVoltage.Value": "3484",
	"EVTargetCurrent.Multiplier": "-1",
	"EVTargetCurrent.Unit": "3",
	"EVTargetCurrent.Value": "10",
	}

or

	$ ./OpenV2G.exe EDi_380_20
	{
	"msgName": "",
	"info": "encodeCurrentDemandResponse finished",
	"error": "",
	"result": "809a02004080c1014181c210e0004080000193f0080c82800030",
	"parameter0": "380",
	"parameter1": "20",
	"debug": ""
	}

Known limitations / ToDos

  • Decoder and encoder for DIN: Some message details are still missing.
  • Only the DIN schema is (partly) supported. ISO schema to be added.

Features / Progress

2022-11-11: The minimum functionality for EVSE side works until the precharge response, so that the Ioniq car responds without errors.
