Error handling
• Ensure the CCS charging plug is in good condition
• Connect the charging plug to the vehicle
• Check plug connection for obstacles to good connection
• Check measured values of the vehicle
The vehicle's charging socket can cause overheating.
• Ensure the CCS charging plug is in good condition
• Connect the charging plug to the vehicle
• Check plug connection for obstacles to good connection
• Check measured values of the vehicle
The vehicle's charging socket can cause overheating.
• Measure the level of the input voltage
• Check existing alarms in the alarm history
• Measure the level of the input voltage
The voltage difference between the phases must not exceed a tol­
erance range.
The high output voltage can be caused by various specific events.
• Repeat the charging process
• Check whether the fault persists
The high output current can be caused by various specific events.
• Repeat the charging process
• Check whether the fault persists
Termination of CAN communication can be caused by various spe­
cific events.
• Repeat the charging process
• Check whether the fault persists
• Check that the SECC is switched on and the LEDs are flashing.
Termination of CAN communication can be caused by various spe­
cific events.
• Repeat the charging process
• Check whether the fault persists
• Check whether the control of the power converter is switched
on and the LEDs are flashing.
The AC contactor has not opened or closed within the prescribed
time limit.
• Check AC contactor to ensure proper condition
The DC contactor has not opened or closed within the prescribed
time limit.
• Check DC contactor to ensure proper condition
The CP status "C" has been lost during the charging process. The
loss of the status may be caused by noise due to bad wiring
between the output of the charging station and the vehicle's char­
ging socket. Bad wiring inside the vehicle can also cause the loss
of status due to noise.
• Measuring the frequency of the alternating current
The charging station is set to an input frequency of 50/60 Hz
±10%.
No fault. The alarm indicates that charging has been stopped by
pressing the button on the HMI.
