Table 5-53 PreChargeReq CAN Signal Mapping
5.5.8.17.2 Common Request Parameter
The PreChargeReq uses EVTargetVoltage and fill with the VCVCCU_Vehicle_LinkVoltage
CAN signal.
The PreChargeReq uses EVTargetCurrent and fill with the
VCVCCU_V2G_EVTargetCurrent CAN signal.
5.5.8.17.3 DC_EVSEStatus Response Parameter
The CAN signals are filled with the parameters of the PreChargeRes according to the table
below.
PreChargeRes
CAN signal
DC_EVSEChargeParameter.DC_EVSEStatus.
EVSENotification
VCVCCU_V2G_EVSENotification
DC_EVSEChargeParameter.DC_EVSEStatus.

Table 5-54 PreChargeRes CAN Signal Mapping
If the PreChargeRes contains
DC_EVSEChargeParameter.DC_EVSEStatus.EVSEIsolationStatus the VC-EVCC
 sets the value in the CAN signal VCVCCU_V2G_EVSEIsolationStatus and
 sets the value of the CAN signal VCVCCU_V2G_EVSEIsolationStatusFlag to 1.
5.5.8.17.4 Common Response Parameter
If the PreChargeRes contains EVSEPresentVoltage the VC-EVCC sets the value in the
CAN signal VCVCCU_V2G_EVSEPresentVoltage.
5.5.8.18 Power Delivery (TRUE)
The VC-EVCC proceeds with the PowerDeliveryReq(TRUE) if
 the PreCharge condition is still fulfilled and
 Vehicle_ContactorStatus is Closed
