(2) Common Trouble Handling
Fault Reasons Suggstions
AC Over-Voltage High Input
Voltage
1. If the voltage exceeds 270Vac for level 2 and 140Vac for
level 1 for a short period of time, the charger will go into
standby mode. Wait for the power network to restore itself to
the normal voltage range, then the charger will automatically
resume charging.
2. If the voltage in the area/community is over 270Vac for level
2 and 140Vac for level 1 for a long time, do not use the charger
until the voltage has returned to the normal range.
AC Under-Voltage Low Input
Voltage
1. If the voltage is lower than 190Vac for level 2 and 90Vac
for level 1 for a short period of time, the charger will go into
standby mode. Wait for the power network to restore itself to
the normal voltage range, then the charger will automatically
resume charging.
2. If the voltage in the area/community is lower than 190Vac
for level 2 and 90Vac for level 1 for a long time, do not use the
charger until the voltage has returned to the normal range.
AC Over current High input
current
1. Immediately connect the distribution box's leakage/over-
current protection circuit breaker.
2. Check for any low impedance or short circuit between the
two output lines of the AC pile.
3. After resolving the above issues, switch the power back on.
If the problem persists, please contact us for assistance.
Over-temperature
High
temperature For
AC pile
Please check the installation environment of the AC charging
pile and ensure that there are no other heating equipment in
the vicinity. It is important to maintain an ambient temperature
below 50°C to prevent overheating and potential damage to
the equipment.
Excessive leakage
current
Excessive
leakage current
1. Immediately disconnect the leakage/over-current protection
switch of the distribution box.
2. Check for any damage or low impedance to the ground or
short circuit in the output line of the AC pile.
3. After troubleshooting the above problems, turn the power
back on. If the problem persists, please contact us for further
assistance.
Ground fault
Failure in
grounding
of the input/
output or inverse
connection of
input L/N
1. Immediately disconnect the leakage/over-current protection
switch of the distribution box.
2. Check if the input/output line of the AC pile is grounded
properly and if the input L/N is connected in the correct
sequence.
3. Once the above problems are identified and resolved, power
on again.
4. If the issue persists, please contact us for further
assistance.
Relay Failure Relay Failure or
Adhesion
1. Restart the charger, let the charger run itself check and
repair.
2. If fault persists. please contact us.
Charger
connection Error
Charger CC/CP
Connection Error
1. Check if there is any damage or loose connection in the
charging gun or cable. Make sure it is securely connected to
the vehicle and the charging station.
2. Restart the charging station and try again.
3. If the fault persists, please contact us.
