Q01 - V2X Authorization Use Case

[mlitre]

OCPP Version

OCPP2.1

Describe the problem

Implement V2X authorization for OCPP 2.1.

Requirements:

• Q01.FR.01: ISO15118Ctrlr.Enabled = true and V2XChargingCtrlr.Enabled = true
• Q01.FR.02: Add EVCCID to idToken in idToken.additionalInfo.additionalIdToken with type EVCCID
• Q01.FR.03/09: Fill NotifyEVChargingNeedsRequest
• Q01.FR.04: Stop Transaction if CSMS rejects NotifyEVChargingNeeds
• Q01.FR.05: Start service renegotiation to start a different energy transfer service (should not happen) --> Seems to conflict with Q01.FR.04
• Q01.FR.06: Stop Transaction if CSMS rejects NotifyEVChargingNeeds and ServiceRenegotiation not possible or failed
• Q01.FR.30/31: Set V2XSupportedOperationModes variable
• Q01.FR.32: Set V2XSupportedEnergyTransferMode variable
• Q01.FR.36: Fill connected EV related device model variables: "Available", "VehicleId", "VehicleCertificate", "ProtocolAgreed", "ProtocolSupportedByEV".

Device model variable to add/check:

• V2XEnabled
• V2XAvailable
• ISO15118Available
• ISO15118Enabled
• ISO15118ServiceRenegotiationSupport
• ISO15118ProtocolSupported
• V2XSupportedEnergyTransferModes
• V2XSupportedOperationModes
• V2XSampledDataTxStartedMeasurands
• V2XSampledDataTxEndedMeasurands
• V2XSampledDataTxEndedInterval
• V2XSampledDataTxUpdatedMeasurands
• V2XSampledDataTxUpdatedInterval
• ConnectedEVAvailable
• ConnectedEVVehicleId
• ConnectedEVVehicleCertificate[Leaf,SubCA1,SubCA2,Root]
• ConnectedEVProtocolAgreed
• ConnectedEVProtocolSupportedByEV --> by instance in order of preferences

Describe your solution

This would require:

• Callback for updating allowed energy transfer modes --> moving to Q02
• Make transaction block aware of what operation mode is in progress to update list of measurands

Additional context

No response

Most of the use case's requirements are done in #1096 and EVerest/EVerest#1200. The missing requirements that are not fulfilled are not required and correspond to the V2X meter values.
These can be added at a later time since it requires the transaction block to be aware of the operation mode, which is more work.
