When the EV is fully charged, the charging will stop and the charger LED indicator will be solid green.
Please end the charging session by scanning the RFID card for a second time. If not scanning the RFID card
again, the charger will not unlock the gun on the charger side and the user cannot plug out the gun.
In charging state before the EV is fully charged, the user can stop charging by scanning the RFID card for a
second time. The charging session will end and the gun on the charger side will be unlocked. Another solution
to stop charging is to end the charging session from the EV side. After the gun on the EV side is unlocked and
plugged out, the charging session will end and the gun on the charger side will be unlocked automatically.
4 Troubleshooting
Problems
Possible Causes
Solutions
Input over voltage
AC input voltage may be too
high.
1. Check the input voltage from the backend.
2. If the voltage is over 456Vac for a short time
,
wait
till the power grid recovers to normal range.
Input under voltage
AC input voltage may be too
low.
1. Check the input voltage from the backend.
2. If the voltage is under 304Vac for a short time,
wait till the power grid recovers to normal range.
Input over current
AC input current may be too
large.
1. Shut off the leakage current protection switch of
power distribution cabinet immediately.
2. Check whether there is low resistance connection
between AC output cables of the charger.
Input over frequency
AC input frequency may be
too high.
1. Check the input voltage frequency from the
backend.
2. If the frequency exceeds 55Hz for a short time,
wait till power grid recover to normal range.
Input under frequency
AC input frequency may be
too low.
1. Check the input voltage frequency from the
backend.
2. If the frequency is lower than 45Hz for short time,
wait till power grid recover to normal range.
