5.5.8.16.2 DC_EVSEStatus Response Parameter
The CAN signals are filled with the parameters of the CableCheckRes according to the table
below.
CableCheckRes
CAN signal
DC_EVSEChargeParameter.DC_EVSEStatus.
EVSENotification
VCVCCU_V2G_EVSENotification
DC_EVSEChargeParameter.DC_EVSEStatus.
NotificationMaxDelay
VCVCCU_V2G_NotificationMaxDelay
DC_EVSEChargeParameter.DC_EVSEStatus.
DC_EVSEStatusCode
VCVCCU_V2G_EVSEStatusCode
Table 5-52 CableCheckRes CAN Signal Mapping
If the CableCheckRes 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 PreCharge
The VC-EVCC proceeds with the PreChargeReq and sets
Vehicle_IsolationMeasurementRequest to not activated if the EVSEProcessing status in
the CableCheckRes is finished and the response code was OK.
The Vehicle_ContactorRequest is set to Close if
 the difference between Vehicle_ContactorVoltage and the Vehicle_LinkVoltage is for
ChargeV2G_PreChargeStabilityTime (500ms) less than 20V and
 Vehicle_IsolationMeasurementStatus is not active.
