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.
3 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 voltage range.
Input lower voltage
AC input voltage may be too
low.
1. Check the input voltage from the backend.
2. If the voltage is under 230Vac for a short time,
wait till the power grid recovers to normal voltage
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 voltage range.
Input lower 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 voltage range.
Over temperature
Temperature may be too low
inside the charger.
1. Check the surrounding conditions of chargers
installed whether there is heating device nearby.
Make sure environmental temperature is under 60
℃
.
Over leakage current
Leakage current to the earth
may be too high.
1. Shut off the leakage current protection switch of
power distribution cabinet immediately.
