5.5.8.15.2 Common Request Parameter

The ChargeParameterDiscoveryReq sets

EVRequestedEnergyTransferType/RequestedEnergyTransferMode

to VCVCCU_V2G_StateM_EnergyTransferMode CAN signal.

Note

The EVSE reports the supported energy transfer modes for DC charging in the

ServiceDiscoveryRes.

The VC-EVCC transmits this information within the CAN signal

VCVCCU_V2G_StateM_EnergyTransferModeFlags.

The supported modes list within the signal

VCVCCU_V2G_StateM_EnergyTransferModeFlags is a binary combination of the

modes mentioned below.

The VC-EVCC supports the following energy transfer modes for DC charging:

DC core (coded as 0x04)

DC extended (coded as 0x08)

DC combo core (coded as 0x10)

DC unique (coded as 0x20)

The unsupported energy transfer modes for DC charging are:

AC single phase core (coded as 0x01)

AC three phase core (coded as 0x02)

The VC-EVCC will stop the charging sequence if unsupported values are requested!

The ChargeParameterDiscoveryReq uses

DC_EVChargeParameter.EVMaximumCurrentLimit

and fill with the VCVCCU_V2G_EVMaximumCurrentLimit CAN signals.
