User Manual VC-EVCC

Caution

The condition “VCVCCU_Inlet_MaxCurrent > VCVCCU_ChargeUnit_MaxCurrent” is

not checked by the VC-EVCC. Both signals and the corresponding values are

transmitted on CAN but there will be no intervention by the VC-EVCC if the value of the

signal VCVCCU_ChargeUnit_MaxCurrent exceeds the value of the signal

VCVCCU_Inlet_MaxCurrent. The VCU has the full responsibility to monitor the current

value and likewise to react in case of exceedance of the maximum allowed current.

5.5.7.2 Charge Error Detection

The VC-EVCC provides a charge error detection. Therefore, the following Diagnostic

Trouble Codes (DTC) are used to indicate missing information or invalid conditions which

are needed for charging.

J1939 Vehicle CAN (CAN1):

 VCVCCU_ChargeFromVehicle E2E fault (0x20E0EA)

Charging Stop Switch (DIN):

 DIN ShortToBat error (DTC 0x04E0E3)

PTC0:

 PTC0 OutOfRange error (DTC 0x05E0E2)

 PTC0 ShortToBat error (DTC 0x05E0E3)

 PTC0 ShortToGnd error (DTC 0x05E0E4)

 PTC0 OpenLoad error (DTC 0x05E0E5)

Control Pilot:

 Control Pilot ShortToBat error (DTC 0x00E0E3)

Position Feedback:

 POS_FB ShortToBat error (DTC 0x02E0E3)

 POS_FB ShortToGnd error (DTC 0x02E0E4)

 POS_FB OpenLoad error (DTC 0x02E0E5)

Hardware Compatibility:

 Hardware Software Incompatibility error (DTC 0x40E0E2)

5.5.8 Charging with V2G

The following chapters describe the V2G charging and its dependencies to certain CAN

signals. Common requests and response are equal within the DIN70121 and the ISO15118.

Differences between the DIN70121 and the ISO15118 are described in separate chapters.
