1 Product Overview
1.1 Product Introduction
The three phase 44KW charger is combination of two 22KW chargers in a floor-standing housing, which
provides AC charging to two electric vehicles simultaneously. It’s equipped with the function of charging by
scanning the RFID card. The RFID card is a key component to start or stop the charging session. The LED
indicators on the left and right panels help you understand what is happening with the charger by indicating
different colors.
With internet connection via a built-in EN-GATE, more functions like monitoring, operation management and
remote upgrade are available on the backend named Charge Management System.
Compatible with all types of cables, the socket locks the charging cable into the charger to ensure a safe
charging. The protection grade of the charger is high as IP54, with the excellent capacity of water and rust
proof, assuring the safe outdoor operation and maintenance. Designed according to Electric Vehicle Charging
System Standard EN 61851-1: 2011 and EN 61851-22: 2002, the charger is compliant with the industrial

3 Charging Operation
3.1 Connect Charger to EV
Park EV near to the charger, take out the charging cable from EV, and plug its guns respectively into the
socket of the charger and the EV. After plug-in, please check the gun is correctly and tightly connected. With
appropriate connection, the charger LED indicator will change to flashing yellow light, which indicates that
the charger is ready for charging.
3.2 Start Charging & Stop Charging
After the charger is connected to EV and ready for charging, scan the RFID card for once on the identification
area of front panel, then the charging starts. When the charging starts, the gun will be locked on the charger
socket. The charger screen will display the running information on the screen, such as charged electricity,
charged time, voltage, current and power.

- 13 -
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.
